Question

For our current programming assignment I need to create a CleanWord method that reads in one variable string at a time and returns a cleaned word without any non letters. The instructions given to us are listed below:

“Clean word” method:

 This is to be implemented as a separate method, so it can be called for either a dictionary word or book word.

 The function will remove any non-letters, except an apostrophe (‘) and numbers from the word.

 All letters will changed to lower case.

 It will then return the updated word. The word could now be blank. The calling method will need to deal with this correctly.

I would appreciate the help!

Language: C++
