C Program : Reverse number and check whether the number is palindrome or not by using unconditional statements.

• C program for Swapping of two Numbers

Palindrome in C:

A palindrome is a method, which is used to reverse the given numbers. If we reverse a palindrome number, it will not change and it won’t give any other meaning. For example 212, 343, 13431, -525, -767 are palindrome numbers.

For finding a given number is palindrome or not,

• Initially we have to reverse it,
• Then compare the given number with the original palindrome number,
• If both are same then number is palindrome else not.
