When a class is both a derived class and a base class it is said to be part of what?

CONCEPT: Multiple inheritance is when a derived class has two or more base classes. 1.

What happens if the base and the derived class contain the definition of a function with the same prototype?

38. What happens if the base and derived class contains definition of a function with same prototype? Compiler reports an error on compilation. Base class object will call base class function and derived class object will call derived class function.

What will happen when derived class object invoke a function which is in the base class also?

Now if we call this function using the object of the derived class, the function of the derived class is executed. This is known as function overriding in C++. The function in derived class overrides the function in base class.

When a function is defined in the derived class with the same name and arguments in the function in the base class it is called?

When the base class method is redefined in the derived class, then it is called method overriding. The signature of the function in the base class and the derived class should be the same.

How derived class is derived from the base class explain with syntax?

The Base class members and member functions are inherited to Object of the derived class. A base class is also called parent class or superclass. Derived Class: A class that is created from an existing class. The derived class inherits all members and member functions of a base class.

Can a base class be derived from a derived class?

The class whose members are inherited is called the base class, and the class that inherits those members is called the derived class. A derived class can have only one direct base class. However, inheritance is transitive.

Which class is the class every other class is derived from?

superclass
The class from which the subclass is derived is called a superclass (also a base class or a parent class). Excepting Object , which has no superclass, every class has one and only one direct superclass (single inheritance).

What will happen if we call a derived class function overridden through a base class object?

If you call a virtual function that has been overridden in class Derived , the call will resolve to Base::virt() , not to the override Derived::virt() . Same goes for using typeid on the this object: the this object really has been demoted to type Base ; it is no longer an object of type Derived .

How do you call a base class function with a derived class object?

However, you can still call their implementation (if they have one) by using a qualified-id. Note that access-specifiers both of class members and base classes have an influence on whether or not you can use a qualified-id to call a base class’s function on an object of a derived type.

When the name of function is same in the base class and derived class the function is called overloaded?

Having a derived class function with the same name as a function in the corresponding base class is called function overloading. When deriving from a private base class, the public, protected and private members of the base class become private members of the derived class.

When the base class and derived class have member functions with exactly the same name same return type and same arguments list then it is said to be?

When the base class and derived class have member functions with exactly the same name, same return-type, and same arguments list, then it is said to be function overriding.
