An integer is a palindrome if the reverse of that number is equal to the original number.

## Program to Check Palindrome

```
#include <stdio.h>
int main() {
int n, reversed = 0, remainder, original;
printf("Enter an integer: ");
scanf("%d", &n);
original = n;
// reversed integer is stored in reversed variable
while (n != 0) {
remainder = n % 10;
reversed = reversed * 10 + remainder;
n /= 10;
}
// palindrome if orignal and reversed are equal
if (original == reversed)
printf("%d is a palindrome.", original);
else
printf("%d is not a palindrome.", original);
return 0;
}
```

**Output **

Enter an integer: 1001 1001 is a palindrome.

Here, the user is asked to enter an integer. The number is stored in variable `n`.

We then assigned this number to another variable `orignal`. Then, the reverse of n is found and stored in `reversed`.

If `original` is equal to `reversed`, the number entered by the user is a palindrome.
