5. Increment and Decrement Operator The ++ and – are increment and decrement operators. The increment operator increases its operand by one; the decrement operator decreases its operand by one. -- ++

8. Examples 6 5 b = a++ 5 4 4 b = --a 5 4 5 b = a-- 5 6 6 b = ++a 5 Final value of a Final value of b Expression Initial value of a
