Multiple Inheritance is a feature of C++ where a class can inherit from more than one classes . The constructors of inherited classes are called in the same order in which they are inherited. For example, in the following program, B’s constructor is called before A’s constructor.

In computer programming languages, the term default constructor can refer to a constructor that is automatically generated by the compiler in the absence of any programmer-defined constructors (e.g. in Java), and is usually a nullary constructor.
Read moreWhat is default copy constructor in C++?
Copy Constructors is a type of constructor which is used to create a copy of an already existing object of a class type. It is usually of the form X (X&), where X is the class name. The compiler provides a default Copy Constructor to all the classes .
Read moreWhat is the use of classes?
The class is a blueprint that defines a nature of a future object. An instance is a specific object created from a particular class. Classes are used to create and manage new objects and support inheritance —a key ingredient in object-oriented programming and a mechanism of reusing code.
Read moreDo I need to use classes in C++?
No, you should not put everything into classes . Whoever told you that was wrong. C++ is not (just) an OO language, it is a multi-paradigm language. Additionally, putting everything into classes does not mean that code is object oriented (especially since for static methods you don’t need actual objects, just types).

Read moreWhat is structure and union with example?
A structure contains an ordered group of data objects . Unlike the elements of an array, the data objects within a structure can have varied data types. Each data object in a structure is a member or field. A union is an object similar to a structure except that all of its members start at the same location in memory.
