Improve the Hangman game by separating the display of letters correctly guessed from letters incorrectly guessed.
Increase the size of the game's array and make the required modifications to the program's code that references it so that you can add additional words to it and provide a bigger pool from which secret words will be randomly chosen.
Add a Checkbox control to the game just under the PictureBox control and use it to give the player the option of displaying or hiding the GroupBox control and its contents. Adjust the size of the form as appropriate.
