Question
Write a program containing a class named CaseConversion.
CaseConversion should contain 3 methods: ToLowercase, ToUppercase,
and ToPropercase. None of these 3 methods should call any functions
or methods themselves. Each method should accept and return one
string or char array (your choice). In your main(), prompt the user
to enter a string/char array, and call each of your 3 methods in
turn, displaying the results of the method in main().
Do not use toupper(), tolower(), or any other function. Do
the conversions using keywords and operators only.
