P-5.12:Implement a program that can input an expression in postfix notation (see C-5.8 below) and output its value.
C-5.8: Postfix notation is an unambiguous way of writing an arithmetic expression without parentheses. It is defined so that if (exp1) o (exp2) is a normal fully parenthesized expression whose operation is o, then the postfix version of this is pexp1pexp2o, where pexp1 is the postfix version of exp1 and pexp2 is the postfix version of exp2. The postfix version of a single number or variable is just that number or variable. So, for example, the postfix version of ((5 + 2) * (8 3))/4 is 5 2 + 8 3 * 4 /. Describe a nonrecursive way of evaluating an expression in postfix notation.
