Palindrome Numbers

Palindrome Numbers - C Programming - Palindrome number in c: A palindrome number is a number such that if we reverse it, it will not change.

Palindrome number in c: A palindrome number is a number such that if we reverse it, it will not change. For example some palindrome numbers examples are 121, 212, 12321, -454. To check whether a number is palindrome or not first we reverse it and then compare the number obtained with the original, if both are same then number is palindrome otherwise not. C program for palindrome numbers is given below.

Palindrome number algorithm

  • Get the number from user.
  • Reverse it.
  • Compare it with the number entered by the user.
  • If both are same then print palindrome number
  • Else print not a palindrome numbers.

Palindrome number program c

#include <stdio.h>
 
int main()
{
   int n, reverse = 0, temp;
 
   printf("Enter a number to check if it is a palindrome or not\n");
   scanf("%d",&n);
 
   temp = n;
 
   while( temp != 0 )
   {
      reverse = reverse * 10;
      reverse = reverse + temp%10;
      temp = temp/10;
   }
 
   if ( n == reverse )
      printf("%d is a palindrome number.\n", n);
   else
      printf("%d is not a palindrome number.\n", n);
 
   return 0;
}
