Im trying to write a program that reads in characters from a user specied input file and
displays the character and the characteristics of the character, e.g., lower
case, etc.
Specically, test if the character:
is a letter.
if the character is a letter, test if it is lower case or upper case.
if the character is a letter, test if it is a vowel or consonant.
is a control character (# is less that 32).
is a digit.
if the character is a digit, test if the value is odd or even.
is a punctuation character.
