Question

Using Windows Form App create an application that determines if an entry from the user is a palindrome. A palindrome is a series of numbers that can be read from left to right or right to left. Examples of palindromes are 22222, 12321 and 89298. A palindrome must be 5 digits long. Using modulus and division evaluate digits one at a time from right to left. The user should enter their palindrome into the palindrome checker application using a text box. When they click a button that says check if palindrome, a label should be populated to prompt the user whether their entry was a true palindrome or not.
