1 00:00:01,210 --> 00:00:03,920 So hello, everyone, and welcome back to the Gores. 2 00:00:04,380 --> 00:00:10,090 So in the last class, we learned about variables and we discussed our first new day type, which was 3 00:00:10,120 --> 00:00:15,240 and so forth through the tape was and. 4 00:00:17,140 --> 00:00:18,970 And this useful starting in Tejas. 5 00:00:21,240 --> 00:00:23,670 And it requires four bites of space. 6 00:00:26,310 --> 00:00:29,610 So in this glass, we will learn various new types. 7 00:00:30,360 --> 00:00:36,780 And we will learn which their type is used for storing, which type of data and how much space we want 8 00:00:36,870 --> 00:00:37,920 for storing that data. 9 00:00:38,820 --> 00:00:39,160 OK. 10 00:00:39,570 --> 00:00:41,390 So let's get started on that. 11 00:00:44,820 --> 00:00:48,390 Fired new empty failure. 12 00:00:50,410 --> 00:00:50,760 Safe. 13 00:00:52,100 --> 00:00:54,710 OK, so let's name it something. 14 00:00:56,990 --> 00:00:58,640 Various data types. 15 00:01:03,550 --> 00:01:06,930 Nazi CPB save. 16 00:01:14,100 --> 00:01:16,670 Has she include your stream 17 00:01:19,440 --> 00:01:23,070 using namespace SDD? 18 00:01:23,940 --> 00:01:25,890 And then I'm having and mean. 19 00:01:30,720 --> 00:01:31,830 And then return to. 20 00:01:38,550 --> 00:01:51,570 OK, so in the last class, we did something like this and I equals 10, so I is variable here and it 21 00:01:51,840 --> 00:01:52,690 is editor type. 22 00:01:56,930 --> 00:01:57,210 OK. 23 00:01:57,600 --> 00:02:01,380 So I told you, did you type tells us two things. 24 00:02:01,940 --> 00:02:07,830 Which do you do you are storing and how much space you need for storing that data. 25 00:02:09,000 --> 00:02:16,310 In case of and I was taught in teachers and I had acquired four by itself, Speace, OK. 26 00:02:17,340 --> 00:02:21,000 So how do I come to learn that indigence required for virtual space? 27 00:02:21,930 --> 00:02:25,110 So basically is a function size off. 28 00:02:26,580 --> 00:02:32,100 I will give Integer as input and it will give me that integrase for bytes of space. 29 00:02:34,200 --> 00:02:37,290 OK, so let's call it. 30 00:02:37,780 --> 00:02:38,790 OK, so let's see. 31 00:02:40,420 --> 00:02:42,210 And I equals 10. 32 00:02:44,100 --> 00:02:55,900 Okay, so first of all, let us Brindabella, if I see out really off variable I is. 33 00:02:59,450 --> 00:03:04,640 I end an end and now does print size off with Ebele. 34 00:03:05,330 --> 00:03:05,960 See out. 35 00:03:09,020 --> 00:03:13,640 Size of gator type and is. 36 00:03:16,250 --> 00:03:19,510 Size of a plane. 37 00:03:20,700 --> 00:03:20,980 OK. 38 00:03:21,650 --> 00:03:23,090 So what should be my output? 39 00:03:25,650 --> 00:03:28,580 So here, the value of FI is down. 40 00:03:29,160 --> 00:03:31,980 And here my output should be fooled. 41 00:03:33,030 --> 00:03:35,640 OK, so Blenman. 42 00:03:40,040 --> 00:03:40,960 So value of very. 43 00:03:41,260 --> 00:03:44,390 Is 10 and size order type in this food? 44 00:03:44,750 --> 00:03:45,900 OK, perfect. 45 00:03:47,210 --> 00:03:48,950 So I can also here like this. 46 00:03:49,970 --> 00:03:52,880 See old size of. 47 00:03:55,230 --> 00:03:58,550 And instead of writing, I. 48 00:03:58,890 --> 00:03:59,820 I can also write. 49 00:03:59,930 --> 00:04:02,090 And so London. 50 00:04:05,160 --> 00:04:05,330 OK. 51 00:04:05,450 --> 00:04:07,700 So you can see outproduce him forward and for. 52 00:04:10,610 --> 00:04:15,980 Let's come into doubt and here my answer is Dan. 53 00:04:18,540 --> 00:04:20,670 And here, my answer is for. 54 00:04:25,990 --> 00:04:28,780 So in the last class, we added two integers. 55 00:04:32,560 --> 00:04:35,180 And I told you, we want desensitising teachers. 56 00:04:36,610 --> 00:04:39,820 Our teachers will not be too large and it will not be too small. 57 00:04:40,230 --> 00:04:40,920 So it will do. 58 00:04:40,960 --> 00:04:46,750 We will use added a type called and intercourse four by itself memory. 59 00:04:49,290 --> 00:04:52,980 OK, so what if if I want to store small integers? 60 00:04:53,760 --> 00:04:56,160 So we have a two day dive called Short and. 61 00:04:58,730 --> 00:05:01,340 Barton, for example, let's say as equals 10. 62 00:05:03,220 --> 00:05:08,560 It will also store integers, but it requires to buy its own space. 63 00:05:10,350 --> 00:05:10,640 OK. 64 00:05:11,260 --> 00:05:19,170 Now, what if if I want to store large integers so I have a data type called long, long, long, long 65 00:05:19,300 --> 00:05:22,690 and let's say L equals 50. 66 00:05:24,260 --> 00:05:31,280 It will also start in business, but it will take eight bites of space, eight bytes of memory. 67 00:05:32,240 --> 00:05:34,520 OK, so let's write code. 68 00:05:44,100 --> 00:06:00,740 OK, so first of all, let us talk about shorthand short as a close 25 see old value of video as is. 69 00:06:03,620 --> 00:06:05,180 And then see out. 70 00:06:09,040 --> 00:06:21,630 Size of data, type short is so you out the size of S and then only. 71 00:06:24,860 --> 00:06:34,760 Okay, so what you do, my output, so the value of faces go into five and the size of as is two bytes. 72 00:06:35,240 --> 00:06:35,510 OK. 73 00:06:35,750 --> 00:06:37,970 Some are butchered between five and two. 74 00:06:38,870 --> 00:06:39,590 So let's see. 75 00:06:41,860 --> 00:06:42,660 Verlinden. 76 00:06:45,780 --> 00:06:50,450 So the value of variable as this 25 and the size of the type short is two. 77 00:06:51,330 --> 00:06:54,210 Okay, so let's give space between IS and 25. 78 00:06:56,860 --> 00:06:57,400 Space. 79 00:07:00,300 --> 00:07:01,410 Now it is looking good. 80 00:07:02,100 --> 00:07:05,620 Well, your variable as this 25 and size water type is, too. 81 00:07:06,540 --> 00:07:13,320 OK, so you can also write here like this sea out size of Schadt and. 82 00:07:17,040 --> 00:07:19,220 And later, OK, so let's move on. 83 00:07:21,360 --> 00:07:22,840 So he gets here to Endou. 84 00:07:23,890 --> 00:07:29,650 So basically you can ride like this size of S and you can also right size up short and they will without 85 00:07:29,650 --> 00:07:29,890 him. 86 00:07:31,130 --> 00:07:34,710 OK, so here my output is 25. 87 00:07:35,590 --> 00:07:38,530 And here my output is to bite. 88 00:07:39,340 --> 00:07:39,590 OK. 89 00:07:40,680 --> 00:07:43,030 OK, so now let us talk about long. 90 00:07:43,030 --> 00:07:43,330 Long. 91 00:07:44,170 --> 00:07:48,360 OK, so first of all you control C control me. 92 00:07:49,340 --> 00:07:49,660 OK. 93 00:07:50,470 --> 00:08:03,820 So long long and L a close let's say 30 C out really of variable. 94 00:08:04,710 --> 00:08:05,410 L is. 95 00:08:07,210 --> 00:08:08,230 And then end line. 96 00:08:11,000 --> 00:08:14,470 Similarly let us bend the size of long long to type. 97 00:08:15,010 --> 00:08:15,820 So we'll see out. 98 00:08:17,980 --> 00:08:22,600 Size of long, long diapers. 99 00:08:24,820 --> 00:08:30,400 Size of L.A. and then and length. 100 00:08:32,620 --> 00:08:32,840 OK. 101 00:08:32,920 --> 00:08:34,460 So what's your dream, Yardbird? 102 00:08:35,740 --> 00:08:41,230 So the value of L is tarty and sighs of hell is it about. 103 00:08:43,320 --> 00:08:46,190 OK, so let's come then. 104 00:08:50,260 --> 00:08:55,480 So the very low variable list would be and size of long integer type, is it perfectly fine? 105 00:08:57,010 --> 00:09:04,510 And just like above, we can also write C out size of long, long. 106 00:09:06,450 --> 00:09:08,650 And then and. 107 00:09:09,660 --> 00:09:11,100 So come by then. 108 00:09:13,160 --> 00:09:15,080 You're going to hear it and it. 109 00:09:16,040 --> 00:09:16,290 OK. 110 00:09:16,570 --> 00:09:17,560 So it is your choice. 111 00:09:17,620 --> 00:09:20,290 You can ride like this and you can also ride like this. 112 00:09:22,180 --> 00:09:24,160 OK, so here my outproduced turkey. 113 00:09:26,110 --> 00:09:30,160 And in this lane, my output is invite's. 114 00:09:32,140 --> 00:09:34,000 OK, so let's revise again. 115 00:09:34,840 --> 00:09:42,880 So if I want to store small integers, I will use short and short and requires two bites of space. 116 00:09:45,050 --> 00:09:45,340 OK. 117 00:09:45,820 --> 00:09:49,810 So if I want to store these in size integers, I will write and. 118 00:09:51,430 --> 00:09:53,890 It requires four bites of space. 119 00:09:55,510 --> 00:10:02,450 And if I want to store large numbers, then I will use long, long and. 120 00:10:03,610 --> 00:10:06,730 And it requires it by its own space. 121 00:10:08,780 --> 00:10:12,560 OK, so how big and how small integers? 122 00:10:12,970 --> 00:10:14,100 I can store in shorthand. 123 00:10:15,100 --> 00:10:17,560 So basically we will seed in our upcoming windows. 124 00:10:18,010 --> 00:10:22,180 Similarly, how big and how small integers I can store it. 125 00:10:22,200 --> 00:10:24,890 And they will also see this in upcoming windows. 126 00:10:25,330 --> 00:10:29,990 And similarly, how big and how small integers began store in long, long. 127 00:10:30,550 --> 00:10:32,520 We will also see it in upcoming videos. 128 00:10:32,820 --> 00:10:33,070 OK. 129 00:10:33,460 --> 00:10:39,850 So basically, just remember that here I am having to buy two space for and I am having for battle space 130 00:10:39,910 --> 00:10:44,290 and for long, long I am having eight bites of space and the minimum. 131 00:10:44,320 --> 00:10:45,720 And what makes them relevant. 132 00:10:45,730 --> 00:10:47,470 These is again storing this to the dive's. 133 00:10:47,980 --> 00:10:49,990 We will see it in our upcoming videos. 134 00:10:51,240 --> 00:10:51,510 OK. 135 00:10:52,800 --> 00:11:04,390 So, OK, so we have covered Tahlia types till now and Qahtan and long, long and OK, so let us see 136 00:11:04,720 --> 00:11:06,370 some unedited types as well. 137 00:11:07,570 --> 00:11:07,750 OK. 138 00:11:08,170 --> 00:11:13,870 So for example, can I write like this and I equals one point two three. 139 00:11:16,140 --> 00:11:17,220 Can I write like this? 140 00:11:17,790 --> 00:11:28,860 No, obviously not, because it can only store integers, individual type can only store integers and 141 00:11:28,860 --> 00:11:30,570 one point two three is not an integer. 142 00:11:31,260 --> 00:11:33,770 So we need an editor type to store when. 143 00:11:33,780 --> 00:11:34,470 One, two, three. 144 00:11:35,470 --> 00:11:39,390 Okay, so we have to digitize that can store floating values. 145 00:11:40,170 --> 00:11:46,170 So this is known as floating values and we have to do the dives that can store floating values. 146 00:11:46,980 --> 00:11:52,070 So I have fostered a type of float flawed F equals 1.0 three. 147 00:11:52,740 --> 00:11:56,490 And I have one more data type that can store floating values. 148 00:11:57,090 --> 00:12:00,220 So double the equals. 149 00:12:00,280 --> 00:12:01,320 One point two, three. 150 00:12:02,320 --> 00:12:03,660 Okay, so floor these are two. 151 00:12:03,660 --> 00:12:07,680 The type that will is also the type both store floating values. 152 00:12:08,160 --> 00:12:09,180 So what is the defense? 153 00:12:09,570 --> 00:12:10,680 Defense is very simple. 154 00:12:11,220 --> 00:12:14,310 Flawed requires four bites of space. 155 00:12:15,970 --> 00:12:18,370 And W need gigabytes of space. 156 00:12:20,800 --> 00:12:21,050 OK. 157 00:12:21,430 --> 00:12:27,850 So just like short term and longer and float has a smaller range and that will has a larger range. 158 00:12:28,840 --> 00:12:29,140 OK. 159 00:12:29,410 --> 00:12:37,940 So since Float has four by its space, it will store B sensors floating loose and that will has it by 160 00:12:37,940 --> 00:12:38,530 those space. 161 00:12:38,650 --> 00:12:40,870 So it can store big floating values. 162 00:12:41,140 --> 00:12:47,370 Fluid can store small floating wells and double can stored large floating will lose. 163 00:12:47,860 --> 00:12:48,940 Let's see an example. 164 00:12:49,660 --> 00:12:54,570 So first of all, nerds come into doubt and similarly commended. 165 00:12:55,810 --> 00:12:59,890 OK, so let us first talk about fluted, a type so flawed. 166 00:13:01,500 --> 00:13:03,880 If it was one point two, three. 167 00:13:04,630 --> 00:13:12,040 Now, first of all, let us spend the value of F sealed value of variable. 168 00:13:12,940 --> 00:13:16,070 F is C out F and then end line. 169 00:13:17,400 --> 00:13:17,610 OK. 170 00:13:18,040 --> 00:13:21,460 So now let us spend size of to type. 171 00:13:21,780 --> 00:13:29,170 So C out size of flawed data type is. 172 00:13:30,460 --> 00:13:31,740 We will use size function. 173 00:13:31,870 --> 00:13:35,740 And we'll give FS input and then enderlin line. 174 00:13:37,030 --> 00:13:39,310 OK, so what should be my output. 175 00:13:41,590 --> 00:13:45,460 So here the value of Pfeifer's one point two three. 176 00:13:45,490 --> 00:13:49,420 So one penalty should be printed and size of efforts for bytes. 177 00:13:50,140 --> 00:13:51,810 Size of floater diapers. 178 00:13:51,880 --> 00:13:52,510 Four bytes. 179 00:13:52,930 --> 00:13:54,130 So four should be printed. 180 00:13:54,790 --> 00:13:54,990 OK. 181 00:13:55,060 --> 00:13:56,030 So let's see. 182 00:13:58,190 --> 00:13:58,710 London. 183 00:14:02,590 --> 00:14:05,890 OK, so first, let us add this line between long, long and flawed. 184 00:14:06,610 --> 00:14:12,040 So condole, see, and then I am having control. 185 00:14:12,870 --> 00:14:14,800 Okay, so now let us run again. 186 00:14:18,610 --> 00:14:24,500 OK, so the value of variable life is one window, three and size up from dirty diapers, food perfectly 187 00:14:24,500 --> 00:14:24,830 fine. 188 00:14:25,520 --> 00:14:33,880 And just like above, you can also read like this see out size of fluid and line. 189 00:14:35,120 --> 00:14:37,440 So basically size of fef and size of. 190 00:14:38,150 --> 00:14:38,990 What will be some. 191 00:14:42,260 --> 00:14:43,280 Food and food. 192 00:14:44,150 --> 00:14:44,660 Perfect. 193 00:14:45,380 --> 00:14:55,880 So let's come into doubt and hear my output is one point two three and hear my output is four bytes. 194 00:14:56,540 --> 00:14:56,850 OK. 195 00:14:57,410 --> 00:15:00,560 So now let us talk about double digit type. 196 00:15:01,340 --> 00:15:07,970 Okay, so first of all, let's copy and paste condole, see and then control me. 197 00:15:13,410 --> 00:15:20,010 OK, so double B equals, let's say, three point two seven five. 198 00:15:21,630 --> 00:15:28,430 So first of all, the sprint, the value of deep sea out will be of variable. 199 00:15:28,490 --> 00:15:32,630 The is the and then end lane. 200 00:15:32,810 --> 00:15:35,620 And now let us spend size of double digit type. 201 00:15:36,080 --> 00:15:44,000 So see out the size of double digit type is. 202 00:15:45,530 --> 00:15:49,920 I will use a size or function and I will give this input. 203 00:15:50,690 --> 00:15:51,170 And then. 204 00:15:51,260 --> 00:15:53,090 And line again. 205 00:15:53,210 --> 00:15:55,040 So virtually my output. 206 00:15:57,200 --> 00:15:58,640 So I live very simple. 207 00:15:59,740 --> 00:16:01,250 Well do you have variable days. 208 00:16:01,310 --> 00:16:02,510 Three point two seven five. 209 00:16:02,870 --> 00:16:05,100 So three point two seven five should be printed. 210 00:16:05,890 --> 00:16:08,530 And similarly, size of your diapers. 211 00:16:08,720 --> 00:16:09,410 Eight bytes. 212 00:16:09,830 --> 00:16:11,060 So each should be printed. 213 00:16:12,480 --> 00:16:12,730 OK. 214 00:16:13,010 --> 00:16:14,940 So let's come, Ballenden. 215 00:16:19,180 --> 00:16:23,200 So the value of variability is steep in 2005 and signs of double digit diapers. 216 00:16:23,380 --> 00:16:23,640 Eight. 217 00:16:24,920 --> 00:16:25,930 And just like above. 218 00:16:26,740 --> 00:16:34,820 You can also ride like this, see out size of double and lane. 219 00:16:35,740 --> 00:16:41,190 OK, so instead of riding the name of the variable, you can directly write the name of the dinner type. 220 00:16:42,060 --> 00:16:43,170 So compiler then. 221 00:16:46,320 --> 00:16:47,550 Aired here and aired here. 222 00:16:48,130 --> 00:16:51,120 OK, so let's Commander Daoud. 223 00:16:52,480 --> 00:17:02,620 So you'll hear my output is three by two, seven five and hear my output is Edomites. 224 00:17:04,530 --> 00:17:14,980 OK, so now we have covered five debates and short and long, long and flawed and. 225 00:17:16,200 --> 00:17:19,560 OK, so let us see some unedited tapes as well. 226 00:17:21,210 --> 00:17:25,570 OK, so can I add like this, Aaron equals character. 227 00:17:26,680 --> 00:17:26,980 No. 228 00:17:27,960 --> 00:17:29,110 Can I write like this. 229 00:17:29,140 --> 00:17:29,540 Flawed. 230 00:17:29,630 --> 00:17:31,090 F equals. 231 00:17:31,230 --> 00:17:31,500 Correct. 232 00:17:32,320 --> 00:17:32,640 No. 233 00:17:33,920 --> 00:17:42,300 But we need added a type that can store characters and the name of this are diapers, cat GABSI equals 234 00:17:42,890 --> 00:17:46,530 a cat is a different type and that can store characters. 235 00:17:47,400 --> 00:17:55,770 OK, so you can write gang C equals A, C equals B, C equals Connecter one. 236 00:17:56,400 --> 00:17:58,140 C equals character zero. 237 00:17:58,950 --> 00:18:04,440 C was like Tacoma, C calls character space and so on. 238 00:18:05,090 --> 00:18:05,390 OK. 239 00:18:06,210 --> 00:18:12,080 Similarly we can write like this, sequels can per dollar and so on. 240 00:18:12,950 --> 00:18:16,090 Okay, so what is the size of cat. 241 00:18:16,380 --> 00:18:18,110 So the size of cat is one bite. 242 00:18:19,810 --> 00:18:21,080 Okay, so. 243 00:18:25,830 --> 00:18:28,520 Fantozzi controlled me. 244 00:18:29,760 --> 00:18:34,580 OK, so Cav sequels. 245 00:18:35,660 --> 00:18:36,310 Let's say. 246 00:18:37,740 --> 00:18:38,030 OK. 247 00:18:39,180 --> 00:18:53,870 And OK, so first of all, let us spent value of variable C C out value off variable, C is C, LC and 248 00:18:53,870 --> 00:18:54,560 then and Lane. 249 00:18:55,610 --> 00:18:58,790 Now let us spend size of gadget or type. 250 00:18:59,210 --> 00:19:08,230 So C out size of cad digit type is we will use sisal function. 251 00:19:08,360 --> 00:19:09,380 And we'll give C. 252 00:19:09,380 --> 00:19:11,930 S input and then and line. 253 00:19:14,370 --> 00:19:15,940 Okay, so, Richard, we are out. 254 00:19:16,360 --> 00:19:23,560 But okay, so the value of variable C is correctly and sizable. 255 00:19:23,580 --> 00:19:24,650 C is one bite. 256 00:19:26,130 --> 00:19:26,960 OK, so. 257 00:19:27,500 --> 00:19:28,670 And one should be blended. 258 00:19:29,000 --> 00:19:32,660 So let's see, Ballenden. 259 00:19:36,180 --> 00:19:41,090 So the value of variable C is E and size of gadgety diapers when. 260 00:19:41,850 --> 00:19:48,570 And just like, whoa, we can also write like this C out size of cat. 261 00:19:50,250 --> 00:19:52,200 And then I ran it. 262 00:19:54,930 --> 00:19:56,130 So when and when? 263 00:19:58,420 --> 00:20:03,520 Blades, Commander Dowd, and hear me out for days, eh? 264 00:20:04,130 --> 00:20:07,610 And here my output is one bite. 265 00:20:08,780 --> 00:20:10,440 OK, so 266 00:20:13,100 --> 00:20:14,150 so what can happen? 267 00:20:14,620 --> 00:20:18,130 Sometimes you just want to store whether something is true or false. 268 00:20:18,750 --> 00:20:19,070 OK. 269 00:20:19,660 --> 00:20:23,080 So sometimes you want to store whether something is true or false. 270 00:20:23,590 --> 00:20:25,180 So in that case, what will I use? 271 00:20:25,330 --> 00:20:27,190 I will use added a type Bouley. 272 00:20:29,040 --> 00:20:29,250 OK. 273 00:20:29,640 --> 00:20:30,810 So I will write like this. 274 00:20:30,970 --> 00:20:35,530 Bowlby equals true, or you can write like this. 275 00:20:35,570 --> 00:20:37,980 Boole B equals four. 276 00:20:39,360 --> 00:20:42,520 So Bull is it the type that has only two Aleuts? 277 00:20:43,200 --> 00:20:46,470 It will be true or it will be false. 278 00:20:47,500 --> 00:20:49,400 OK, so what is the size of bull? 279 00:20:49,880 --> 00:20:51,710 Sizable is when by only. 280 00:20:54,690 --> 00:20:54,920 OK. 281 00:20:56,330 --> 00:21:01,290 So you can also say blue means one and false means zero. 282 00:21:02,550 --> 00:21:04,320 OK, so let's see. 283 00:21:08,770 --> 00:21:09,450 We'll see. 284 00:21:10,660 --> 00:21:11,390 And then control. 285 00:21:13,140 --> 00:21:15,740 OK, so let's take a variable. 286 00:21:18,180 --> 00:21:31,690 It goes to C out really of variable, B is CLB and then end lane. 287 00:21:32,520 --> 00:21:45,560 And similarly, size of bool Deeter type is used sisal function and give B as input and then end lane. 288 00:21:46,410 --> 00:21:47,850 OK, so virtual real output. 289 00:21:50,490 --> 00:21:54,490 OK, so be close to Proem insulin. 290 00:21:54,810 --> 00:21:59,140 So when we live in turnier assembly size of bees, one bite. 291 00:21:59,250 --> 00:22:01,350 So my output will be one and one. 292 00:22:02,400 --> 00:22:03,780 So let's combine and then. 293 00:22:06,550 --> 00:22:11,240 So value of variable B is when one means through zero means for us. 294 00:22:11,830 --> 00:22:14,520 And similarly, the size of bullying diapers when. 295 00:22:16,090 --> 00:22:18,820 And just like above, you can read like this. 296 00:22:19,610 --> 00:22:22,840 See out size of wood. 297 00:22:23,560 --> 00:22:23,850 OK. 298 00:22:24,640 --> 00:22:25,060 And line. 299 00:22:29,070 --> 00:22:30,450 One bite and one bite. 300 00:22:31,650 --> 00:22:32,990 OK, so let's come into doubt. 301 00:22:34,440 --> 00:22:34,680 OK. 302 00:22:34,740 --> 00:22:37,680 So what will happen if I ride false here? 303 00:22:39,950 --> 00:22:40,420 Foiled. 304 00:22:41,910 --> 00:22:42,960 So nothing will change. 305 00:22:43,200 --> 00:22:44,610 Only the relief will change. 306 00:22:45,100 --> 00:22:51,950 You will be printed here, compile and run and you can see zero is. 307 00:22:52,490 --> 00:22:55,380 OK, we'll have a live very welby's foiled netted zero. 308 00:22:58,740 --> 00:23:07,520 OK, so what will happen if I write and G it quotes Ben and then I am printing Jim. 309 00:23:10,710 --> 00:23:11,640 So what will happen? 310 00:23:14,770 --> 00:23:16,020 So the value of variable J. 311 00:23:16,150 --> 00:23:18,220 Is 10 and I am printing. 312 00:23:18,370 --> 00:23:19,320 Well, your variable J. 313 00:23:19,400 --> 00:23:21,580 So 10 should be printed as expected. 314 00:23:22,150 --> 00:23:23,530 So let's see. 315 00:23:28,110 --> 00:23:30,550 OK, so Dennis printed perfectly fine. 316 00:23:31,810 --> 00:23:34,680 Now, what will happen if I remove this stain? 317 00:23:36,190 --> 00:23:37,330 Now what will be printed? 318 00:23:37,900 --> 00:23:39,310 Now what should be our output? 319 00:23:41,460 --> 00:23:42,150 So let's see. 320 00:23:43,680 --> 00:23:55,260 So when I was writing and I equals Ben Dover, this line was doing, this line was giving me four bites 321 00:23:55,260 --> 00:23:55,800 of space. 322 00:23:57,810 --> 00:24:02,670 I was naming this piece as I and I was putting Ben inside it. 323 00:24:03,810 --> 00:24:08,610 But when I am writing Entergy, then what will happen? 324 00:24:09,420 --> 00:24:13,080 This line will give me four bites of memory. 325 00:24:14,470 --> 00:24:16,190 I am naming this memory as G. 326 00:24:16,660 --> 00:24:19,120 But I am not putting inside it anything. 327 00:24:19,500 --> 00:24:21,560 OK, so I am not putting anybody inside it. 328 00:24:22,090 --> 00:24:24,490 So what will happen if I bring the value of G. 329 00:24:26,160 --> 00:24:28,590 So the answer is anything can be printed. 330 00:24:29,410 --> 00:24:30,720 I am not going anywhere, Lou. 331 00:24:31,230 --> 00:24:32,450 So anything can be rendered. 332 00:24:33,060 --> 00:24:33,340 OK. 333 00:24:33,630 --> 00:24:35,540 So let's see. 334 00:24:40,960 --> 00:24:43,120 So this value is getting printed. 335 00:24:44,540 --> 00:24:46,840 OK, so we call this Ray Lewis garbage. 336 00:24:47,830 --> 00:24:49,000 So what is happening here? 337 00:24:51,820 --> 00:24:58,960 This line is giving me four bites of memory as expected, and I'm naming this memory S.G., but I'm 338 00:24:58,960 --> 00:25:00,550 not putting anybody inside it. 339 00:25:01,090 --> 00:25:02,020 So what is happening? 340 00:25:02,180 --> 00:25:03,730 There will be a garbage value. 341 00:25:05,730 --> 00:25:09,340 OK, so there will be a garbage velu inside this four bites. 342 00:25:09,470 --> 00:25:12,860 And when I am printing G, when I am printing G. 343 00:25:13,040 --> 00:25:15,080 So this garbage value is getting printed. 344 00:25:16,790 --> 00:25:18,230 OK, so let's see one more time. 345 00:25:21,660 --> 00:25:23,730 So this garbage value is getting printed. 346 00:25:27,940 --> 00:25:36,890 OK, so let's see when one example, flawed G, C out G and Lane. 347 00:25:37,790 --> 00:25:39,260 OK, so what should be our output? 348 00:25:39,380 --> 00:25:41,350 Sound output will be a garbage value. 349 00:25:41,570 --> 00:25:42,710 So let's Blandon. 350 00:25:46,230 --> 00:25:48,570 So this is our output, which isn't garbage value. 351 00:25:49,110 --> 00:25:51,200 So this thing happened with a videotape. 352 00:25:51,780 --> 00:25:53,100 So let's see one more example. 353 00:25:54,510 --> 00:25:57,900 Bouley B to see out. 354 00:25:59,060 --> 00:25:59,710 We do. 355 00:26:00,560 --> 00:26:00,920 And then. 356 00:26:01,030 --> 00:26:01,530 And then. 357 00:26:02,400 --> 00:26:07,810 OK, so what will be our output to the output will either be a zero or it can be when. 358 00:26:08,520 --> 00:26:10,890 So Boulez's on you two values zero and one. 359 00:26:11,220 --> 00:26:12,470 So anything can be rendered. 360 00:26:12,570 --> 00:26:13,770 Zero can also be printed. 361 00:26:13,900 --> 00:26:15,210 One can also be printed. 362 00:26:15,810 --> 00:26:16,790 So let's run it. 363 00:26:19,930 --> 00:26:21,250 So zero is getting printed. 364 00:26:22,510 --> 00:26:23,980 And let's take one more example. 365 00:26:27,180 --> 00:26:30,100 See, you do see out. 366 00:26:30,880 --> 00:26:31,940 Si do. 367 00:26:32,470 --> 00:26:33,320 And an airplane. 368 00:26:35,330 --> 00:26:39,160 OK, so OK, so which connectivity be painted? 369 00:26:40,770 --> 00:26:45,240 So the answer is any good actor can be rendered any good, which correctly will be Bolinder. 370 00:26:46,290 --> 00:26:47,840 So let's come by. 371 00:26:50,490 --> 00:26:52,020 So bees getting vented. 372 00:26:53,170 --> 00:26:53,370 OK. 373 00:26:55,630 --> 00:26:57,100 So I hope you heard the logic. 374 00:26:57,280 --> 00:26:58,150 What is happening here? 375 00:26:58,720 --> 00:27:05,440 For example, in case of character, I am getting one bites of space and I am naming this piece as you 376 00:27:05,440 --> 00:27:08,140 do, but I am not putting the 10 sided. 377 00:27:09,280 --> 00:27:10,970 Today will be a default data. 378 00:27:11,190 --> 00:27:13,170 And we call this to your tires and garbage. 379 00:27:13,840 --> 00:27:16,020 OK, so why do we call this garbage? 380 00:27:16,110 --> 00:27:17,520 Because it is of no use. 381 00:27:18,060 --> 00:27:19,650 It is of no use for us. 382 00:27:22,390 --> 00:27:24,810 OK, so let's see. 383 00:27:26,960 --> 00:27:29,590 Let us discuss the last topic for today's class. 384 00:27:30,400 --> 00:27:32,440 That is naming off variables. 385 00:27:34,930 --> 00:27:36,880 Naming of variables. 386 00:27:38,920 --> 00:27:40,010 So there are fewer rules. 387 00:27:40,810 --> 00:27:41,090 OK. 388 00:27:41,440 --> 00:27:43,870 So what characters you can use for naming a variable? 389 00:27:44,110 --> 00:27:45,950 You can use small ABC. 390 00:27:46,480 --> 00:27:47,910 You can use capital ABC. 391 00:27:48,550 --> 00:27:52,690 You can use numbers like I have used here. 392 00:27:52,780 --> 00:27:54,500 B to C two. 393 00:27:55,450 --> 00:27:55,660 OK. 394 00:27:56,660 --> 00:28:02,650 OK, so one thing to note here is your variable name cannot start with a number. 395 00:28:02,890 --> 00:28:03,790 So this is wrong. 396 00:28:04,360 --> 00:28:05,730 And this is right. 397 00:28:06,490 --> 00:28:09,880 So your variable name cannot start with the number. 398 00:28:10,870 --> 00:28:11,740 And one more thing. 399 00:28:12,400 --> 00:28:14,460 Your variable name cannot be like. 400 00:28:14,830 --> 00:28:17,150 And first number. 401 00:28:18,520 --> 00:28:19,480 So this is wrong. 402 00:28:19,810 --> 00:28:22,690 You cannot give spaces between your variable name. 403 00:28:23,050 --> 00:28:24,100 You can read it like this. 404 00:28:24,480 --> 00:28:26,340 And first underscore them. 405 00:28:27,640 --> 00:28:28,510 So this is right. 406 00:28:28,600 --> 00:28:29,440 And this is wrong. 407 00:28:29,800 --> 00:28:30,060 OK. 408 00:28:31,210 --> 00:28:31,420 OK. 409 00:28:31,480 --> 00:28:33,520 So two things are very important here. 410 00:28:33,910 --> 00:28:37,180 First, you are variable name cannot start with that number. 411 00:28:37,480 --> 00:28:40,770 And second, you cannot give space between yet. 412 00:28:40,880 --> 00:28:41,560 Very big name. 413 00:28:42,590 --> 00:28:42,870 OK. 414 00:28:44,390 --> 00:28:46,240 OK, so that is all for this video. 415 00:28:46,630 --> 00:28:47,070 Thank you.
