11.2 Programming a little game.

HERE IS THE GAME WE WANT TO PROGRAM:



The program chooses an integer between 0 and 32 and memorizes it. Then, a dialog box opens and asks the user to enter an integer. If this integer is equal to the saved integer, it displays “WIN” in the text zone. Otherwise, the program indicates if the saved integer in greater or lesser than the user’s integer and reopens the dialog box. The program will end when the user has found the correct integer.



We need to use the primitive random:

For example, random 20 returns an integer randomly between 0 and 19.



HERE ARE THE RULES TO CREATE THIS GAME:

• The number choosen by the computer will be stored in a variable called number.
• The dialog box will be named “Give an integer please”
• The number choosen by the user will be stored in a variable called try.
• The main procedure will be named game.

SOME POSSIBLE IMPROVEMENTS:

• Displays the number of tries.
• The computer’s number will be between 0 and 2000.
• Check that the user enters a valid number. You can use the primitive number?.
  
  Examples:

  number? 8 returns true.

  number? [5 6 7] returns false.

  number? "abcde returns false
