This document discusses writing a macro called swap(t,x,y) that swaps two arguments of any data type t. It asks the user to input a data type and two values of that type, then swaps the values and displays the output. It explains how to swap two integers by using a temporary variable and applying the same concept to arguments of any type t by using macros. The objective is to understand macro preprocessing in C.

11. Assignment 2
It will work only for 2 integer arguments, so how will
you swap 2 arguments of type t? (t means it can be int,
char, short, float, string or double).

It will work only for 2 integer arguments, so how will
you swap 2 arguments of type t? (t means it can be int,
char, short, float, string or double).
 Use MACROS.
 Write a Multiline MACRO to swap 2 arguments of type t.
