You can do something like this though:

#define Max(x, y) (((x) > (y)) ? (x) : (y))

I'm not pissed about anything. Though I was a bit annoyed that you kept ignoring the valid help by saying it didn't answer your question. This suggests that all you want is the answer and you couldn't care less about learning anything.

Here's what happens when i try to avoid w and z:

> cat a.c

(Toggle Plain Text)

#include <stdio.h>
#define SmartMax(x,y)  (y>x) ? y : x 

int main()
{
 int x=8,y=6;
 SmartMax(x,y)=100;
 printf("%d\n",x);
 return 0;
}

> gcc -x c a.c
a.c: In function `main':
a.c:7: invalid lvalue in assignment

Maybe you could run down to Wal-Mart, buy some attention span, and re-read the thread.

does that come in a spray-can or a tube?

Topical application couldn't be effective. For optimal attention span enhancement, I'd advise a suppository.

You're being bitten by the fact that some operators have higher precedence than others. Look at nnxion's post for a solution that addresses this.

Maybe you should get out more.

So formally, should the code in my first post return "y 6" or "y 100"?
