Answer 1

Answer:

Output of C programs | Set 32

Predict the output of the following C programs.

1. What will be the output of following program?

Input:

1 3

#include<stdio.h>

int main()

{

int a, b;

if(scanf("%d%d", &a, &b)==2)

printf("true");

else

printf("false");

return 0;

}

Output:

True

Explanation: Scanf function returns integer value as its return type is integer. In the above question, if you will enter two integer values, then it will return 2. It means “if condition” becomes true, otherwise “if condition” becomes false.

2. What will be the output of following program?:

#include<stdio.h>

int main()

{

int a=0;

a=a++ + a++ - a++ + ++a;

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

return 0;

}
