Today we will review memory allocation in C++ and go over the basic tool for managing memory, the pattern Resource Acquisition is Initialization or RAII, and introduce Copy Constructors and the Assignment Operator.

• Warmup
• Allocation using new
• Freeing memory using delete
• RAII
• Rule of 3 (now 5)
• A dynamic array version of Bag.

In-class Exercise: DynamicBag

Lets define and implement a dynamically-sized Bag ADT

1. Download the starter code
2. In dynamic_bag.hpp define the class DynamicBag conforming to the BagADT interface.
3. Extend dynamic_bag_tests.cpp to implement tests for the methods using Catch.
4. In dynamic_bag.tpp implement the DynamicBag methods.
5. Build your code locally as you work.
6. Submit your dynamic_bag.hpp, dynamic_bag.tpp, and dynamic_bag_tests.cpp files collected into a zip file via Canvas at the Assignment "Exercise for Meeting 8". You can create this zip file using the CMake submission target.
