}these are he solution of my assigmnets 2 and three
In Assignment No.2 and 3 we added basic code in header and implementation files in the form of necessary attributes with suitable data types along with Constructor, Destructor and Getters/Setters for all data members and all other relevant functions belongs to “Topic” and “Sub topic” classes.
In this assignment we will finalize our coding by adding different relations among different classes (lesson, course, study program, topic and sub-topic), and writing main program for our complete sub-system.
Note: For two classes “Topic” and Sub-topic” you have already developed full code in last assignment. In this assignment, you just need to relate with other classes mentioned above that you can see and help from object model
please help me
