Abstract
Reversing a number in the C/C++ program means interchanging the digits i.e. to bring the last digit of the given number to the first position or vice versa.
Scope of the Article
This article provides a basic understanding regarding reversing a number and the algorithm for the same.
Different methods to implement the same in C.
Prerequisites
One should have a basic understanding of C/C++
Understanding regarding how loop and recursion work.
Introduction
As we know that reversing a number means interchanging the digits so that the last digit of the number comes first or vice versa.
Let us understand the same with the help of an example:-
Given input is 56897.
Then reverse of the given number would be 79865.
As we have understood what is meant by reversing a number, let us go further into understanding its algorithm.
