C++ Program for Number Swapping

A Few days back when I was in Delhi, one student asked me how to write a c Plus Plus program to swap two numbers by using the temp variable. I had make understand the logic behind this program to that student and said I will write this program for you.

This is a very simple & easy C++ (C Plus Plus) program for number swapping. In the below program, we swapped two numbers using the temporary variable.

Swap two numbers without using third variable

Output is:

Before swapping.
x = 15, y = 10
After swapping.
x = 10, y = 15
