        Due date:  Wednesday, 03/11/2009


        Exercise 3.23, parts a and b, page 110:

        Write a program in which the driver simply calls a function 
        named inToPostfix which reads an infix expression from
        standard input and writes the equivalent postfix expression
        to standard output.  The infix expression includes operands,
        parentheses, and operators, where the operands are single 
        lowercase characters, and the operators are +, -, *, /, and
        ^ (exponentiation).
 
        Use the STL container stack to store a stack of characters.
        Include error checks in the code.

        Your program should be implemented in a single file named
        hw5.cpp and emailed to the grader, Payal Khimani,
        psk0025@unt.edu.

        Also, submit a source code listing in class on the due date.
        Your code should include comments, and your name should appear
        at the top of the file.
