Download and unzip these files, and load them into your favorite environment: DLLTaskManager.zipDownload DLLTaskManager.zip You are given: MainDLL.cpp: the main function TaskManager.cpp/.hpp: the interface for the task manager, which uses the doubly linked list Task.cpp/.hpp: the declarations and definitions for the Task class, the data type stored in our Task Manager DNode.hpp: the class declaration for the DNode class DNode.cpp: a shell for the DNode class definitions DLL.hpp: the class declaration for the doubly linked list class DLL.cpp: a shell for the DLL class definitions Additionally, you are given 2 example input files of tasks to test with. You'll want to place these files in the same folder as the rest of the code (but they do not get added to the build target - that's just for compilation). It's a lot easier to read long lists of inputs from a file than having the user type them out every time. The TaskManager class handles the file input for you. Modify MainDLL.cpp to change the file. You will need to write: Constructor definitions for the DNode class: 5pts Method definitions for the DLL class: 2 constructors: 7pts void push(string n, int p, int t, int m): 5pts Task *pop(): 5pts
