• When a class is derived from a base class, it automatically acquires variables and methods from base class. This phenomenon is called inheritance.

• When we derive a new class from a given base class, we have to specify the method of derivation. Here, keywords public, private and protected are used. Therefore, Turbo C++ manual calls these terms as access modifiers. (It is important to note that these terms are also called access specifiers, when they are present inside ...
