Question

#include<stdio.h>
#define foo(x,y) x/y
int main()
{
Printf("%d",foo(8+4,2+4));
Return 0;
}

Answer 1

It will evaluate 4, 2 because they are the ones next to the comma that shows what values are to be passed to foo. 4/2 = 2. Then it will add 8+2+4 = 14

Answer 2

foo(8+4,2+4)
== 8+4/2+4
== 8+2+4
== 14.
