How ans is 444

Question

#include<iostream>
using namespace std;
#define MIN(a,b) a>b?b:a

main()
{
int a=2,b=3,c;
c=MIN(++a,++b);
cout<<a<<b<<c;
}

Answer 1

Interesting.

When you "passed" ++a and ++b, the macro acts as:

++a > ++b ? ++b : ++a

In the code, this will cause a to be incremented twice instead of once.

Answer 2

@yuri

Tbh, if you want a comment from me, I'd say that the above example shows how macros should be avoided (instead of prefix/postfix operators).

Answer 3

the more I know about increments the more crazy I get.
it seems to be on safe side, one should avoid increments as much as possible. C/C++ people can disagree, but it could be a reason why ++ is not in Python.
