C++ help:

Design and implement a class of postfix calculators. Use the algorithm given in this chapter to evaluate postfix expresions as entered into the calculator. Use only the operators +, -, *, and /. Make sure to implement the algorithm (Evaluating Postfix Expressions 6.3.1) as a function. (not as part of main). Note while C does have the atoi function it may be easier to simply subtract the char '0' from the char digit.
