# C Program to Reverse a Number using Loops2 min read

In this tutorial, we will write a C program to reverse a number using loops. Before that, you may go through the following topics in C.

To reverse an integer in C is achieved using loop and operators. For example, if the input number is 123 then the program should give 321 as a result.

We will learn three ways to display the number in reverse order in C.

All of the programs below take the user input for an integer. Then using three different loops in C, we calculate the reverse of the number entered. The final result is displayed at the end.
