What is the output of these code? And why?

Question

#include <stdio.h>

//Compiler version gcc 6.3.0
#define max(a,b)a>b?a:b;
int main(void)
{
int m,n;
m=3+max(2,3);
n=2*max(3,2);
printf("m is %d ,n %d" ,m, n);
return 0;
}

Answer 1

for this program to work as desired you need to enclose a>?a:b in bracket and remove semi-colon after the macros

#define max(a,b) ((a>b)?a:b)
