66 - Shorthand Operators

perators Involving LValues (i.e. a variable or something that can be assigned to)

1. a += e is equivalent to a = a + e. The operators -=, *=, /=, %=, |=, &= and ^= are defined accordingly

2. a++ and a-- are equivalent to a += 1 / a -= 1 but the expression itself still has the previous value of a

3. In contrast, --a and ++a have the same effect on a but return the value after the change
