Write a program that evaluates an arithmetic expression in postfix notation. The basic algorithm is contained in

Question:

Write a program that evaluates an arithmetic expression in postfix notation. The basic algorithm is contained in “Evaluating Postfix Expressions” on page 345. Assume the input contains numbers (but no variables) as well as the arithmetic operations +, –, *, and /. Your program should allow the user to evaluate additional expressions until the user wants to end the program. You might also enhance your program so that the expression need not be well formed, and if it is not well formed, then the user must re-enter the expression.
