A compound assignment operator like += or -= is an operator that does two things at the same time: first, it peforms a calculation; and second, it assigns the calculated value to a variable or constant.
Review the following two examples:
totalPoints += 95; same as totalPoints = totalPoints + 95
finalGrade -= 30; same as finalGrade = finalGrade – 30
With your teammates, discuss the possible benefits, if any, of using a compound operator vs. the alternative. Can you think of any drawbacks to using compound operators?
