Write a program to simulate the design process of the course. First, create a struct for the course which consists of following members: course number (int type, e. g. 1200), course start data (int type, e. g. 20200107), course hours (int type, how many hours per week) and lecturer ID (int type). Second, create a struct for lecturer, which has following members: lecturer ID (int type), lecturer office hours (int type, how many office hours per week) and course teaching(array[int] type)). Third, create a struct for student, which as following members: student ID (int type), course taken(array[int] type). Then answer following questions 1, 2, and 3 based on these structures:
