Thread: problem in macro

Hi,

I have 2 questions regarding macros..

Problem 1:

I have to write a program to find greatest of 3 numbers and add greatest number to smallest one.I have done as follow:

Code:

#include<stdio.h>
#include<stdlib.h>

#define MAX(a,b,c) ((a>b && a>c)?a:0 || (b>a && b>c)?b:0 || (c>a && c>b)?c:0);

int main()
{
    int x,y,z;
	int temp;
	temp= MAX(44,57,600);
	printf("%d",temp);
	getchar();
}

I am able to get the greatest number but not able to add with smallest.

Problem 2:

Can any body tell me how to return string from a macro ?
Is it possible or macro always return integer or float values?
I have searched but didn't get any code related to that...

Thanks
