Counters

A counter is typically just an integer variable that you add to or subtract from to keep count of something.

• Keep track of the number of guesses a user has made
• Keep track of the number of moves a user has made
• Keep track of a score
• Keep track of lives/health

There are more than one ways that you can add a number to a variable:

Ex. Add 1 to a counter

• intCounter = intCounter + 1

OR

• intCounter += 1

Ex. Subtract 1 from a counter

• intCounter = intCounter - 1

OR

• intCounter -= 1

Ex. Add 5 to a counter

• intCounter = intCounter + 5

OR

• intCounter += 5
