1 00:00:03,680 --> 00:00:05,680 Hello, everyone, and welcome back to the cause. 2 00:00:06,170 --> 00:00:09,950 So in the last class, we did two programs in those two programs. 3 00:00:10,070 --> 00:00:15,800 What we did was we just took two integers and we added them in the end of their example. 4 00:00:15,890 --> 00:00:19,970 We just took a few integers and we converted simple interest based on them. 5 00:00:20,850 --> 00:00:24,710 OK, so let's make those problems a little more interesting. 6 00:00:25,340 --> 00:00:25,940 So. 7 00:00:29,610 --> 00:00:36,390 Instead of taking and I quote, Spin and Jagels fifteen. 8 00:00:38,130 --> 00:00:40,940 We will let the user give us what are the two numbers? 9 00:00:40,990 --> 00:00:42,270 But do they want us to add? 10 00:00:43,670 --> 00:00:48,520 For example, use it will give us the values of principle read. 11 00:00:50,240 --> 00:00:51,740 And based on these values. 12 00:00:52,100 --> 00:00:53,860 We will conclude our simple interest. 13 00:00:55,110 --> 00:01:00,690 OK, so what we want now is we want our program to start taking input from the user. 14 00:01:05,630 --> 00:01:12,680 OK, so our program was in Dagestan and Jake was fifteen and Gabler's hypoplastic, and then I was sprinting 15 00:01:12,900 --> 00:01:13,190 gey. 16 00:01:16,990 --> 00:01:20,170 OK, so let us first run this program. 17 00:01:20,470 --> 00:01:21,730 So what should be my output? 18 00:01:22,330 --> 00:01:24,400 And plus fifteen Nerdist 25. 19 00:01:24,490 --> 00:01:25,830 So the value of case 25. 20 00:01:26,320 --> 00:01:28,110 So my output should be 25. 21 00:01:28,660 --> 00:01:28,910 OK. 22 00:01:29,230 --> 00:01:31,360 So let's build and then. 23 00:01:36,130 --> 00:01:40,490 OK, so 25 is getting printed and these two lines are also getting printed. 24 00:01:41,030 --> 00:01:43,850 But why these two lines are getting printed. 25 00:01:44,240 --> 00:01:48,710 So basically these two lines tells us that your program has finished its execution. 26 00:01:48,980 --> 00:01:49,270 OK. 27 00:01:51,930 --> 00:01:56,730 OK, so before we learn how to take in perfect loser, I wonder discuss one more thing. 28 00:02:01,690 --> 00:02:04,160 OK, so when we write in time. 29 00:02:05,600 --> 00:02:08,930 So this line is called Declaration. 30 00:02:10,400 --> 00:02:16,010 We declared a variable eye when we arrived and I was 10. 31 00:02:16,850 --> 00:02:18,220 So this line is called. 32 00:02:20,600 --> 00:02:26,630 So this line is called declaration plus initialization. 33 00:02:31,190 --> 00:02:33,770 And when we ride and die. 34 00:02:35,000 --> 00:02:37,640 And then the next line, when we write, I call Spain. 35 00:02:38,120 --> 00:02:41,690 So this line is called declaration. 36 00:02:42,560 --> 00:02:45,140 And this line is called assignment. 37 00:02:47,920 --> 00:02:49,120 We declared a very. 38 00:02:50,030 --> 00:02:52,630 And I sign a valy of 10 to my variable. 39 00:02:52,840 --> 00:02:56,430 I similarly here I declared my variable, I. 40 00:02:56,840 --> 00:02:58,310 And I initialize my variable. 41 00:02:58,310 --> 00:02:59,600 I do then. 42 00:03:00,310 --> 00:03:00,620 OK. 43 00:03:01,380 --> 00:03:04,370 So obviously, let's come back to our equation. 44 00:03:04,390 --> 00:03:05,800 How debate in Britain leaves a. 45 00:03:09,980 --> 00:03:16,880 OK, so now the thing that I want do changes, I want this I n g to be input from the user. 46 00:03:17,870 --> 00:03:21,050 So we will use an inbuilt functionality called Thien. 47 00:03:24,820 --> 00:03:29,470 So we will use an inbuilt functionality guard see in. 48 00:03:30,270 --> 00:03:32,700 Sarin is used to take input from the user. 49 00:03:33,180 --> 00:03:40,350 And just like sealed in is also defined in a file called Ustream, which we have already included in 50 00:03:40,350 --> 00:03:40,860 our called. 51 00:03:42,110 --> 00:03:48,480 OK, so how to print, for example, and take Wilston?
