Lecture 9 Objectives

KNOW:

• How the bag functions are implemented in Chapter 4 (using a dynamically-allocated array to hold the bag items)
• Why a class that uses dynamically allocated memory must define a copy constructor, an overloaded assignment operator, and a destructor

BE ABLE TO:

• Write a copy constructor for a class that uses dynamically allocated memory
• Write an overloaded assignment operator for a class that uses dynamically allocated memory

Sample Exam Question:

Suppose there is no copy constructor defined for the bag class implemented in Chapter 4. Draw a picture and provide a short explanation of what can go wrong if a bag object is passed as a value parameter to a function.
