What functions can be inherited from base class in C++?
What functions can be inherited from base class in C++?
Constructors, destructors and copy constructors of the base class. Overloaded operators of the base class. The friend functions of the base class.
Can class inherit friend function of base class?
No, friend functions are not inherited. Why would a base class function work on a derived class object? Because friend function is using the data members available in base class only.
How can base class function be used in derived class?
To modify the way a function defined in a base class works in the derived class, simply redefine the function in the derived class. Note that when you redefine a function in the derived class, the derived function does not inherit the access specifier of the function with the same name in the base class.
How do you inherit a function in C++?
Inheritance (C++ only)
- Inheritance is a mechanism of reusing and extending existing classes without modifying them, thus producing hierarchical relationships between them.
- The inheritance mechanism lets you use a statement like obj.
- You can also add new data members and member functions to the derived class.

What are the 5 types of inheritance in C++?
C++ supports five types of inheritance:
- Single inheritance.
- Multiple inheritance.
- Hierarchical inheritance.
- Multilevel inheritance.
- Hybrid inheritance.
What is not inherited from the base class C++?
In C++, friend is not inherited. If a base class has a friend function, then the function does not become a friend of the derived class(es). Constructors are different from other class methods in that they create new objects, whereas other methods are invoked by existing objects.
How do you inherit private members of base class in C++?
The private members of a class can be inherited but cannot be accessed directly by its derived classes. They can be accessed using public or protected methods of the base class. The inheritance mode specifies how the protected and public data members are accessible by the derived classes.
How do you call a base class constructor from a derived class in C++?
To call the parameterized constructor of base class when derived class’s parameterized constructor is called, you have to explicitly specify the base class’s parameterized constructor in derived class as shown in below program: C++
Which function is declared in a base class that has no definition relative to the base class?
pure virtual function
A pure virtual function is a function declared in the base class that has no definition relative to the base class.
How are protected members of a base class?
If a class is derived privately from a base class, all protected base class members become private members of the derived class. Class A contains one protected data member, an integer i . Because B derives from A , the members of B have access to the protected member of A .
