Translate an Infix Expression to Postfix

[xIamAxel]

The program I need written is:

Write an object oriented C++ program to translate an infix expression to postfix (Reverse Polish notation. Your input directions should be very clear, perhaps showing an example input. The code should be able to handle nested parentheses.

Can someone do this program so I can understand how it works?
