C Program to Check Whether a Number is Palindrome or Not

In this example, we will try to learn about how to check whether the number entered by the user is a palindrome or not while using c programming.

An integer can be called as a palindrome only if the reverse of that number is equal to the original number.
So let us move forward on how to check our see program, and then we will review the output of our program.

Program to Check Palindrome

#include <stdio.h>
int main()
{
int n, reversedInteger = 0, remainder, originalInteger;
printf("Enter any integer: ");
scanf("%d", &n);
originalInteger = n;
// reversed integer will be stored in the variable 
while( n!=0 )
{
remainder = n%10;
reversedInteger = reversedInteger*10 + remainder;
n /= 10;
}
// palindrome if orignalInteger and reversedInteger are equal to each other
if (originalInteger == reversedInteger)
printf("%d is a palindrome. \n", originalInteger);
else
printf("%d is not a palindrome. \n", originalInteger);
return 0;
}

Output of Code

Enter an integer: 101
101 is a palindrome.
