Character Converter

[userco]

The uppercase member function convert all lowercase letters converted to uppercase. If a character is already uppercase, or is not a letter, it should be left alone.
• The properWords member function accepts a string object consisting of words
separated by spaces and returns it with the first letter of each word converted to
uppercase.

Either you declare the functions (line 3/4) inside the class and implement them outside

or

you implement the function inside the class without the declarations (line 3/4).
