#include <stdio.h>
#define ISEQUAL(X, Y) X == Y
int main()
{
#if ISEQUAL(X, 0)
printf("Geeks");
#else
printf("Quiz");
#endif
return 0;
}
Output of the above program?
Answer: A
Correct answer: Geeks
The macro expands to X == 0, and inside a #if the undefined identifier X becomes 0. The condition is therefore 0 == 0, which is true, so printf("Geeks") is the line that survives preprocessing.
