Project 2 - some text manipulation

A palindrome is a word that is spelled the same backwards as it is forward. For example, the word madam is a palindrome.

Requirements

The following is a brief list of requirements:

• The application takes a line of text from the keyboard.
• It should fail if the line is blank or contains a non-alphabet character.
• Any text entered should be converted to either lower- or upper-case.
• The word should be tested in a separate function to see if it is a palindrome. If it is, the function should return true; otherwise it should return false.
• The calling function should output whether the inputted text is (or not) a palindrome.

Code notes

The palindrome function should be recursive.
