In this tutorial, you will learn how to check whether the number is palindrome or not in C programming. Before that, let us understand the Palindrome number.

## What is a palindrome number?

A number is said to be a Palindrome number if it remains the same when its digits are reversed or are the same as forward. It can also be applied to the word, phrase, or other sequences of symbols.

For **example**: 14141, 777, 272 are palindrome numbers as they remain the same even if reversed. If we take the example of ‘mam’ or ‘madam’, these are also palindrome words.

**C Program to Check Whether a Number is Palindrome or Not**

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 | #include <stdio.h> int main() { int num, revNum = 0, remainder, originalNum; printf("Enter the Number: "); scanf("%d", &num); originalNum = num; //storing by reversing the number while (num != 0) { remainder = num % 10; revNum = revNum *10 + remainder; num /= 10; } // check if originalNum and revNum are equal or not if (originalNum == revNum) printf("%d is a palindrome Number", originalNum); else printf("%d is not a palindrome Number", originalNum); return 0; } |

**Output:**

`//Run 1`

Enter the Number: 121

121 is a palindrome Number

//Run 2

Enter the Number: 245

245 is not a palindrome Number
