Macro C Language

 What is macro? Define a macro to compute maximum of two arguments passed to it.

A macro is a fragment of code which has been given a name. Whenever the name is used, it is replaced by the contents of the macro. There are two kinds of macros. They differ mostly in what they look like when they are used. Object-like macros resemble data objects when used, function-like macros resemble function calls.

#include <stdio.h>

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