Write a C program to check whether a number is palindrome or not

Palindrome Number :

A number is called Palindrome number when original number or entered number is equal ( same ) to reverse number of original number. For the example suppose enter number is = 121 and reverse of 121 will be 121. So 121 is a palindrome number.
