Suppose you have written a class named system. Then when you write System in the Code, the compiler does not know whether you

A. Identify the level of the scope B. Identify the class to which the member belongsC. Define the scope of a member. D. specify the scope. Scope Symbol: the class name is generally followed by the member name of the class. c ++ is used as an example to prevent different classes from being distinguished by the scope when they have members with the same name.For example, a and B indicate two classes. both A and B have members member. SoA: Member indicates the member in Class.B: Member indicates
