Learning Objectives
The purpose of this lab is to give you an opportunity to learn the following skills:
- Refactoring existing code if necessary.
- Learning how to implement multi-level undo redo.
- Applying object-oriented design principles to develop an elegant solution.
Implementing Multi-Level Undo and Redo in the FreeCell Game
For this lab, please do the following activities:
- If necessary, refactor/redesign your initial solution based on the design principles you’ve seen in the lectures and labs.
- Make a plan how you are going to implement undo and redo. Discuss your plan with the lab instructor and make sure that you understand the requirements of the multi-level undo redo features. Being able to design an elegant solution is one of this lab’s main objectives, so please put significant effort to come up with a good design.
- Add the multi-level undo and redo features to your FreeCell implementation. Please ask questions if you need clarification.
