What is the output?

Question

#include<stdio.h>
int main()
{
int i=1;
for(printf("1") ; !printf("2"); printf("3"))
{
printf("\n hii");
}
return 0;
}

Answer 1

for(printf("1") ; !printf("2"); printf("3"))
{
printf("\n hii");
}

printf("1") is executed. Program checks for condition, printf("2") is executed.
!printf("2") evaluates to false, the loop contents do not run, increment statement is not executed.

Output: 12
