1) A palindrome is a number or a text phrase that reads the same backward as forward. For example, 12321, 55555, 45054.

a) Write a base class CharPalin that reads in an array of n chars and determine whether it's a palindrome.

b) Write a derived class StrPalin which inherits from the base class in a), and overwrite the function which checks for palindrome. In this case we want to check for text string palindrome. This means a sentence like Tracy, no panic in a pony-cart. is also a palindrome.
