In programming, it is common to use assignments to modify the contents of a variable. Remember that everything to the right of the equals sign is evaluated first, so we can say:
myVar = myVar + 5;
to add 5
to myVar
. Since this is such a common pattern, there are operators which do both a mathematical operation and assignment in one step.
One such operator is the +=
operator.
myVar += 5;
will add 5
to myVar
.
Convert the assignments for a
, b
, and c
to use the +=
operator.
