GCO4020/CSC428 - Advanced Object Oriented Techniques In C++
Week 4

 

Topic 8: Wrappers

Exercises

Synopsis

Exercise 1

Suggest why it might be desirable to create a Stack class wrapper, rather than just using an Array directly to implement a stack.

There is a sample solution for Exercise 1.

Exercise 2

Suggest a situation in which it would be clearly preferable, or even necessary, to encapsulate an implementation¤ class¤, rather than inherit from it.

There is a sample solution for Exercise 2.

Exercise 3

Explain why neither the inheriting nor the encapsulating version of Stack contains (or needs to contain!) any error checking code.

There is a sample solution for Exercise 3.
