Some list of palindrome numbers is: 2 11 22 111 222

Example: How to check a number is palindrome or not using a function in c.

#include<stdio.h>

int check(int n) {
   int r, rev = 0;

   while (n > 0) {
       r = n % 10;
       rev = rev * 10 + r;
       n = n / 10;
   }
   return rev;
}

int main() {

   int n, p;

   printf("Enter a number:");
   scanf("%d", &n);

   p = check(n);
   
   if (p == n) {
       printf("Number is palindrome:%d", n);
   } else {
       printf("Number is not palindrome:%d", n);
   }

   return 0;
}

Output:

Enter a number:121                                                                                                                     
Number is palindrome:121
