1 00:00:02,020 --> 00:00:03,550 Hey, guys, what's up? 2 00:00:03,880 --> 00:00:08,500 So in this video, we will talk about inmate Sarte function. 3 00:00:09,100 --> 00:00:14,260 OK, so we know Selection's art, we know what is bubbles art. 4 00:00:15,850 --> 00:00:20,590 But these two algorithms take time to implement. 5 00:00:21,460 --> 00:00:23,050 Take time to implement. 6 00:00:24,220 --> 00:00:30,160 So what happened is this sartin thing, this sorting thing is very common. 7 00:00:31,210 --> 00:00:38,220 So since this thing is very common, C++ has given us an inbuilt function, this identity. 8 00:00:39,070 --> 00:00:39,780 So what we have to. 9 00:00:39,820 --> 00:00:40,180 Right. 10 00:00:40,360 --> 00:00:41,920 For example, this is NRD. 11 00:00:42,890 --> 00:00:51,120 LifeSize in, so we just have to write Sarte a comma, a plus in and out. 12 00:00:51,220 --> 00:00:52,750 Eddie, we'll get started. 13 00:00:54,240 --> 00:00:58,620 OK, so this is inbuilt SRT function, so let's see. 14 00:01:01,800 --> 00:01:03,250 So I have already made a file. 15 00:01:03,450 --> 00:01:06,450 The name of the file is Inbuilt Sort Dot CPB. 16 00:01:07,200 --> 00:01:09,750 So I am taking the number of elements. 17 00:01:10,230 --> 00:01:14,580 So this is my input and I am printing the edit here. 18 00:01:15,270 --> 00:01:26,430 So what I need to do is I will write, start a comma, a bless and and my error is now sorted. 19 00:01:26,870 --> 00:01:27,070 OK. 20 00:01:27,420 --> 00:01:29,020 So is the name of the error. 21 00:01:29,770 --> 00:01:31,740 And and is the size of the error. 22 00:01:32,160 --> 00:01:32,410 OK. 23 00:01:32,640 --> 00:01:34,380 So I get started. 24 00:01:34,920 --> 00:01:35,430 Let's see. 25 00:01:37,350 --> 00:01:38,890 So the compiler is giving me error. 26 00:01:39,220 --> 00:01:40,090 And what is the error? 27 00:01:40,570 --> 00:01:43,580 So the error is compiler don't know what is sought. 28 00:01:44,020 --> 00:01:44,340 Why? 29 00:01:44,680 --> 00:01:45,250 Because. 30 00:01:48,970 --> 00:01:53,010 So Combiner is giving me adare at line number 14. 31 00:01:54,430 --> 00:01:58,740 It is saying that, hey, buddy, I don't know what do you mean by sort? 32 00:01:59,560 --> 00:02:06,040 So what happened is just like seen Nancy out there, both are defined in a high profile call IO stream. 33 00:02:06,850 --> 00:02:12,010 Similarly, Saadeh function is defined in a file called algorithm. 34 00:02:14,380 --> 00:02:21,440 So we have to include this had to file into our record so that this line works, OK? 35 00:02:23,530 --> 00:02:28,750 So the functionality of Sarte is defined in our head of file called algorithm. 36 00:02:29,230 --> 00:02:33,750 So we have to include that terrified into our code. 37 00:02:34,180 --> 00:02:34,570 So. 38 00:02:35,350 --> 00:02:36,370 And go rhythm. 39 00:02:40,380 --> 00:02:41,640 Now, let us come by again. 40 00:02:44,530 --> 00:02:50,470 Led to a number of elements out of five and that elements are five, four, three, two and one. 41 00:02:51,790 --> 00:02:52,750 This is my output. 42 00:02:54,130 --> 00:02:57,620 OK, so this are doing things look OK? 43 00:02:57,680 --> 00:03:03,170 So why we need to include this had profile because the functionality in the definition of this function 44 00:03:03,350 --> 00:03:05,230 has been defined in this file. 45 00:03:05,840 --> 00:03:08,020 And we have to include this file into other gold. 46 00:03:08,390 --> 00:03:11,180 They use this inbuilt SART function. 47 00:03:12,080 --> 00:03:12,430 Okay. 48 00:03:14,360 --> 00:03:15,650 OK, so let's discuss. 49 00:03:15,860 --> 00:03:16,670 One last thing. 50 00:03:19,450 --> 00:03:22,330 So what happened is we have many other finds. 51 00:03:23,350 --> 00:03:26,110 We have many header files. 52 00:03:26,740 --> 00:03:29,470 For example, we have hash include. 53 00:03:31,400 --> 00:03:32,150 I team. 54 00:03:34,330 --> 00:03:35,630 We have c met. 55 00:03:36,820 --> 00:03:42,490 We have algorithm, we have hashing included vector. 56 00:03:43,540 --> 00:03:45,460 We have hash included stack. 57 00:03:46,090 --> 00:03:49,120 We have hash included Q and many more. 58 00:03:49,510 --> 00:03:52,060 So we have many header files. 59 00:03:54,270 --> 00:03:54,450 OK. 60 00:03:54,580 --> 00:03:55,960 So we have many other files. 61 00:03:56,260 --> 00:03:59,170 So it is not possible to remember each one of them. 62 00:04:00,380 --> 00:04:00,610 OK. 63 00:04:00,890 --> 00:04:06,110 So, for example, here, if I don't know, invert I to this sword function is defined. 64 00:04:06,380 --> 00:04:09,200 Then I want to be able to use this sword function. 65 00:04:09,790 --> 00:04:10,200 OK. 66 00:04:10,820 --> 00:04:17,720 So there are many header files in C++ and it is not possible to remember the names of all their files. 67 00:04:18,350 --> 00:04:23,330 So we have something called Master Header File. 68 00:04:26,530 --> 00:04:35,760 So the name of this monster had to file is bits slash, S2, DC plus plus dot edge. 69 00:04:36,400 --> 00:04:36,650 OK. 70 00:04:36,910 --> 00:04:44,950 So if you will include this had defined in your code, then all the header files that exist in C++ will 71 00:04:44,950 --> 00:04:46,000 get included. 72 00:04:47,770 --> 00:04:48,910 OK, so one more time. 73 00:04:51,120 --> 00:04:59,820 So if you will include this file in your code, then all that defies in C++ will be included. 74 00:05:00,180 --> 00:05:03,450 That is the reason they call it master header file. 75 00:05:04,140 --> 00:05:06,090 And why do we need this had to file? 76 00:05:06,450 --> 00:05:11,820 Because there are many other files in C++ and we cannot remember all of them. 77 00:05:13,060 --> 00:05:14,770 So what we will do now is. 78 00:05:16,250 --> 00:05:20,450 We will remove both of them and we will right here. 79 00:05:24,500 --> 00:05:31,400 We will right here, bits slash as DDC plus plus dot edge. 80 00:05:32,090 --> 00:05:34,220 OK, so this is Master had to file. 81 00:05:34,790 --> 00:05:38,110 From now on, we will use this header file in other gold. 82 00:05:38,450 --> 00:05:38,830 OK. 83 00:05:41,850 --> 00:05:46,290 So a number of elements are five and the elements are three to one, four and five. 84 00:05:47,190 --> 00:05:52,810 OK, so one, two, three, four, five is getting printed and the compiler is not showing us error. 85 00:05:53,240 --> 00:05:53,490 OK. 86 00:05:53,730 --> 00:05:58,180 So I have not included a lot of them either file and the compiler is not showing us error. 87 00:05:58,250 --> 00:05:58,570 Why? 88 00:05:58,920 --> 00:06:05,670 Because this master had to file has included all their files of C++ language. 89 00:06:06,030 --> 00:06:08,490 OK, so that is the reason this. 90 00:06:08,550 --> 00:06:10,280 So our function is not giving us error. 91 00:06:10,680 --> 00:06:17,850 Similarly, this scene and S.L function are also not giving us edit because I ostrem file is also included 92 00:06:17,910 --> 00:06:18,930 in this had to file. 93 00:06:21,340 --> 00:06:21,670 OK. 94 00:06:22,070 --> 00:06:24,740 So from now on, I will use this had to file. 95 00:06:26,170 --> 00:06:28,070 OK, so this is it for this video. 96 00:06:28,180 --> 00:06:28,780 Thank you.
