Add C program to check if a number is a palindrome

[Praanjaljain29]

This commit introduces a C program that checks whether a given integer is a palindrome. The program takes an integer as input, reverses it, and compares the reversed number with the original. If both are equal, the number is identified as a palindrome; otherwise, it is not. The implementation uses a while loop for reversing the number and conditional statements for comparison. This program is efficient and works for both positive and negative integers
