00:00Hello everyone, in my last video I have explained the flowchart of display first three odd numbers.

00:12I have explained with a dry run that how we will get the first three odd numbers.

00:18Now I'm going to implement this program in C, so I'm going to open a new file.

00:29One empty file, I will save it also, then hash include what strdio.h, I will use what

00:56main, first of all I'm going to make the program in while loop and then I'm going to make the

01:04same program in for loop. I need the variables for odd number od to count the number of odd

01:14numbers that is i, I will define the value odd number that is 1 and I will initialize the value

01:22of i also that is 1. Now I will apply the loop while i less than equal to 3 as the loop is going

01:33to carry on for three times. First of all I will use the printf and what slash n odd a number is

01:44%d where it is, it is inside od, so it's going to display and od equals to od plus 2, so we are

01:56going to get the next odd number and i equals to i plus 1, so we are going to get the next

02:05incrementation in the counter variable.

02:08So this is the program friends, let me save it by using ctrl s and click on the build and see

02:18if there is any error or not, so it's showing zero error and I'm going to run it, so it displayed 1,

02:273 and 5. Now let us quickly understand how the things work, I've taken two variables,

02:33the first odd number is 1 as going to count with the counter variable i, so the value of i is also

02:391, while the value of i is less than 3, so yes here 1 is less than 3, the condition is true,

02:49so it's going to print the first odd number that is odd number is 1, then 1 plus 2 that is what 3,

02:57here 1 plus 1 that is what 2, it will come to the while loop, 2 less than 3 condition is true,

03:05so the next value which is there inside od that is what 3 that is going to print,

03:10then 3 plus 2 that is what 5, so remember the value of od it is what 5,

03:172 plus 1 what is now another value of i, it's 3, again it will go to the while loop,

03:223 equals to 3 the condition is true, what was the last value inside od it was 5,

03:28so it's going to display and 5 plus 2, 7 here it will be what 3 plus 1, 4

03:36come to the while loop, 4 less than 3 the condition is false, so the loop will terminate

03:43and we will get the results that is 1, 3 and 5. So I hope you understand, in the next video

03:50we will see some another program of loop. Bye.
