Program 2 : To print from 1 to 100 numbers.

Program 2 :

#include<stdio.h>

main()

{

int i;

for(i=1;i<=100;i++)

{

printf("%d\n",i);

}

}

Output:-

1
2
3
4
5

.
100

Explanation :

1.)initialises i as an integer. 2.)Now i=1 and is lesser than 100 so condition satisfies and prints the value of i which is 1.
3.)Now i is incremented to '2' and again it is less than 100 so condition satisfies and prints the value of i which is '2'.
4.)It goes like that until i is equal to 100 and it is equal to 100 so it prints 100 than the value of i is incremented to 101 which dissatisfies the condition causing to come out of the loop.
5. As there are no statements out of the loop the program terminates.
