Find Number of Upper and Lower Case Letters in a Command Line Argument String.

It should mean that if there is a string "KoaaLa" then the program will say that there are two uppercase letters and four lowercase letters. But this program converts all characters to that case which it begins to calculate how many letters are with a case.
