Write down the rules for ++ and -- operators.

Rules for ++ and -- operators :

i) Increment (++) and decrement (--) operators are unary operators and they require variable as their operands.


ii) When postfix ++ (or --) is used with a variable in an expression, the expression is evaluated first using the original value of the variable and then the variable is incremented(or decremented) by one.


iii) When prefix ++ (or --) is used in an expression, the variable is incremented (or decremented) first and then the expression is evaluated using the new value of the variable. The precedence and associatively of ++ and --operators are the same as those of unary + and unary -.
