Let us learn how to subtract two numbers using pointers in C programming using user-defined functions with an output.

The C program for subtraction of two pointers makes use of the de-reference operator, also known as the asterisk (*). The user-defined function used here makes use of the call by reference approach.

What is a Pointer?

A pointer is a variable which can be used to store the memory address of another variable which is of the same data-type.
