- Put yourself in the shoes of someone trying to answer this. Can you really imagine anyone can? What are you expecting the answer to this could be?
- How does it not work? What did you do? What were you expecting, and what happened instead?
- Ask yourself: is there enough information for anybody who’s not you to figure out what the problem is?
- Notice how asking a question that is too vague will only get you more questions in return.

    // this would be ok, because it's a "declaration" like "private string courseName;" above
    Student[] studentarray = new Student[3]; 

    // this isn't a declaration and can't exist directly in the class scope:
    studentarray[0] = student1;

    // instead theoretically something like this (within a methods scope):
    public void SomeMethod()
    {
        studentarray[0] = student1;
        // "theoretically" because "student1" isn't known here
    }
    
    // makes a tiny bit more sense:
    public void SetStudent0(Student student)
    {
        studentarray[0] = student;
        // only a tiny bit because this method would have the fixed purpose
        // of assigning to array index 0
    }
    // you would call it outside of this class like so: someCourse.SetStudent0(student1);

    // some more sense:
    public void SetStudent(Student student, int index)
    {
        studentarray[index] = student;
        // only some more sense because from outside this class you don't know which
        // array indices would be valid
    }
    // you would call it outside of this class like so: someCourse.SetStudent(student1, 0);

    // even more sense:
    private int ArrayCursor = 0;
    public void AddStudent(Student student)
    {
        studentarray[ArrayCursor] = student;
        ArrayCursor++;
        // will only work as long as there's enough space in the array
    }
    // you would call it outside of this class like so: someCourse.AddStudent(student1);

    // best with a generic list:
    private List<Student> Students = new List<Student>();
    public void AddStudent(Student student)
    {
        Students.Add(student);
