For this lab we will create a container class using pointers. Our container is called Line and the Line container holds the Point class. The Point class is very simple and already implemented. For this lab: Implement the Line member functions Use a pointer to an array of Points to hold your Point class You cannot use existing container classes. Some container classes are implemented as container adaptors and use an encapsulated object of a specific container class as its underlying container. This assignment will not implement a container adaptor. Implement a main() to test your Line class implementation. Include adding multiple Point objects to your line to force your Line to expand. The attached tar file contains the Point and Line class definitions as an Eclipse project

Below are the
