PROTECTED

Question

So does this mean that you can access a protected variable online from a derived class whose base class has the said variable and you cannot access it directly from an object of the derived class?

Answer 1

Yes that is true.

Protected is not public

you cannot do this in the main class

Customer C1 = new Customer();
Console.WriteLine(C1.ID) (6.17 in video)

It is almost private.
But if you derive a a class from customer (7.36 in video)

public class Corporate Customer : Customer
{
public void PrintID
{
CorporateCustomer CC = new CorporateCustomer();
Console.WriteLine(CC.ID);
}
}

You are allowed to access ID because CorporateCustomer is derived from the customer class.
