4. 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. ++ --

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