Will the following program print the message infinite number of times?
#include<stdio.h>
#define INFINITELOOP while(1)
int main()
{
INFINITELOOP
printf("IndiaBIX");
return 0;
}
Answer: Option
Explanation:
Yes, the program prints "IndiaBIX" and runs infinitely.
The macro INFINITELOOP while(1) replaces the text 'INFINITELOOP' by 'while(1)'
In the main function, while(1) satisfies the while condition and it prints "IndiaBIX". Then it comes to while(1) and the loop runs infinitely.

There is something called "stack overflow" Why do you pose such ambiguous questions?

what would have been the answer, if instead of while(1) it was while(0)?

@Bhumica, In case of while (0) the condition of while loop is false (0 = false). Hence while loop is not executed, so NOTHING will be printed.
