Character Converter Class
Create a CharConverter class that performs various operations on strings. It should have
the following two public member functions to start with. Your instructor may ask you to
add additional functions to the class.
• The uppercase member function accepts a string and returns a copy of it with 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 of words separated by spaces
and returns a copy of it with the first letter of each word converted to uppercase.
Write a simple program that uses the class. It should prompt the user to input a string.
Then it should call the properWords function and display the resulting string. Finally, it
should call the uppercase function and display this resulting string. The program
should loop to allow additional strings to be converted and displayed until the user
chooses to quit.
