In the word game Hangman, a player tries to guess the letters of a hidden word:

The word to be guessed is "hidden" by dint of the fact that it's written in white font on a white background!

Write VBA code to allow you to play the game with a friend (your computer, possibly). A good start would be to hide all of the shapes which make up the gallows, using code something like this:

Sub HideGallowsInitially()

Dim GallowsShape As Shape

For Each GallowsShape In ActiveSheet.Shapes

'hide the next shape in the gallows

GallowsShape.Visible = msoFalse

Next GallowsShape

End Sub

Note that when you loop over a collection of shapes, you have to prefix the name of the Shapes collection with a reference to the worksheet which contains them.

Here are some ideas for functions (not subroutines) that you could include in your code. If you're not sure of the difference between a function and a subroutine, see the relevant pages in your courseware manual.

What the function could do	Value returned	Data type
Loop over the shapes in the gallows to determine if any remain invisible.	True if the player still has more guesses left; False otherwise	Boolean
Loop over the cells in the word to be guessed, determining if any remain white.	True if the word has been fully guessed; False if some letters remain invisible.	Boolean
