C Program To Reverse A Number

C program to reverse a number

C program to reverse a number, in this program we are given a number and we will reverse it, it is a simple program that is most commonly asked. It is a short program that is mostly used as a little part in big programs, we will use two integer type variables to make this program.

Description of c program to reverse a number

We will take two integer type variables 'n' and 'reverse' with initial value 0, we will first ask the user to insert a number and will store it in 'n', then will use while loop for the condition 'n!=0' then will multiply reverse with 10 and store it in reverse only. In next step we will 'n%10' to reverse and again store the value in reverse and finally divide the n by 10 and store in n and will print it as output.

C program to reverse a number

#include <stdio.h>
 
int main()
{
   int n, reverse = 0;
 
   printf("Enter a number to reverse\n");
   scanf("%d", &n);
 
   while (n != 0)
   {
      reverse = reverse * 10;
      reverse = reverse + n%10;
      n       = n/10;
   }
 
   printf("Reverse of entered number is = %d\n", reverse);
 
   return 0;
}
