https://technotip.com/7908/c-program-...

Lets write a C program to swap 2 numbers using pointers and function.

When we call the function, we pass the reference or address of the variable, so this method is called "Call by Reference".

Expected Input and Output
Enter values for a and b
100
200

Before swapping: a = 100 and b = 200

After swapping: a = 200 and b = 100
