“&&” and “and” operator in C

Question

I am trying to calculate the Greatest Common Denominator of two integers.

C Code:

#include 

int gcd(int x, int y);

int main()
{
             


        

Answer 1

It is compiling to you because I think you included iso646.h(ciso646.h) header file. According to it and is identical to &&. If you don't include that it gives compiler error.
