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.
