Problem

Implement a program that can input an expression in postfix notation (see Exercise C-5.8) and output its value.

Problem C-5.8

Postfix notation is an unambiguous way of writing an arithmetic expression without parentheses. It is defined so that if "(exp₁ )op(exp₂)" is a normal fully parenthesized expression whose operation is op, then the postfix version of this is "pexp₁ pexp₂ op", 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.
