The Team table should include fields for the type of team (e.g., basketball), coach's name (both last and first), and the season the sport is most active (S for spring, F for Fall, or B for both). The Athlete table should include fields for student number, student first and last names, and type of sport. Use the same identifier for type of sport in both tables to enable the tables to be related and linked. Populate the tables with sporting teams from your school. Write a C# program that displays information about each team, including the names of the athletes. The data base we have provided to us just need to know how to program it in with the other guidelines given.

A portion of this data structure follows.The records show that the first student (array element 0, id 1111) is taking Section 1 of CIS120 for 3 credits and Section 2 of HIS001 for 4 credits; the second student (array element 1, id 1234) is not enrolled, and so on. Define the necessary data types for creating this structure. Provide operators for creating the original array of student ID numbers, inserting a student’s initial class schedule, adding a course, and dropping a course. Write a menudriven main function to use this structure. Menu-driven main function can be something like this: After each operation that the user selects, it will show a menu and will wait for the user’s input.
