Program to check whether a Number is a Palindrome

Below is a program to check whether a number is a palindrome or not.

A palindrome is a number or a string which is similar when read from the front and from the rear. For example: 121 or Oppo etc.

#include<stdio.h> #include<conio.h> void main() { int a, b, c, s = 0; clrscr(); printf("Enter a number:\t"); scanf("%d", &a); c = a; // the number is reversed inside the while loop. while(a > 0) { b = a%10; s = (s*10)+b; a = a/10; } // here the reversed number is compared with the given number. if(s == c) { printf("The number %d is a palindrome", c); } else { printf("The number %d is not a palindrome", c); } getch(); }

Enter the number: 121 The number 121 is a palindrome
