4-6: More on Nested If Statements

Exercise 4-4: Improving the Guessing Game (continued)

Realising that we need a variable to keep track of the number of guesses remaining, lets call it guessesRemaining, and also realising that it should be declared as Integer, the first question we should resolve is where to declare this variable. The options are either global (outside of any event subprogram) or local (inside an event subprogram, probably the Check It click event).

Choose an answer.declare locally (in the New event)declare globally

The second question to consider is where - in which event(s) - this variable, guessesRemaining, should be initialised? It should be clear that the initial value, i.e. each time a new game is started, should be 7. The events we have implemented in the program are the following:

• (form) New event
• btnCheckIt_Click event
• btnPlayAgain_Click event
• btnExit_Click event

(Hint: the variable must be initialised in two events.)
