I need help figuring out the following errors in my code: replacing the correct
letters the user inputs in the mystery word. My last method's function is to do this but
I cannot figure out why it will only input a single correct letter and not all of the correct guesses. Also the maximum number of tries the user has is 8 but when I compile my program the number of tries will go into the negatives and I cannot figure out what is wrong with my maximum tries loops. Thank you in advance! I really appreciate this. **Also using several methods in this program is a requirement for my assignment!
