Prefix expressions operate on Left-Hand-Side (sometimes called LValue) expressions.
There are two prefix operators:
++ performs a numeric increment on the operand
-- performs a numeric decrement on the operand
These can also be classified as additive operators and because they modify a value in place, they also imply that an assignment takes place as well.
