Write in C++

Implement a program that can input an expression in postfix notation (see Exercise C-5.8) and output its value. As you can see, you will need to read Exercise C-5.8 to complete this programming task.

Exercise 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 pexp₁ pexp₂o, 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.
