1. Modifiy the code so that the guess word can be any length (utilize the length method for this).

2. Add code to display the number of guesses left.

3. Add code to determine if the user has already used a letter and prompt user when they have already guessed the letter. Do not include the letter in the number of incorrect guesses.

4. Add code to display the letters the user has already guessed. Display the information immediately before prompting the user to enter another letter.
