The two base classes have members of the same name

The base class and derived class have members of the same name

Two base classes derive from the same base class

Overview

Multiple inheritance (multiple inheritance): a derived class has two or more base classes that inherit required properties from two or more base classes. To adapt to this situation, C++ allows a derived class to inherit multiple base classes at the same time. This kind of behavior is called multiple inheritance.

Advantages and disadvantages

It naturally extends the single inheritance.

Can inherit the functions of multiple classes

Shortcoming

Structural complication

Priority ambiguity

Functional conflict

Declare the method format of multiple inheritance

Format of multiple inheritance:

Derived class constructor name (total form parameter table list): base class 1 constructor (actual parameter table list), base class 2 constructor (actual parameter table list), base class 3 constructor (actual parameter table list) {example of newly added members in a derived class according to member initialization statements}

Teacher class:

# ifndef PROJECT5_TEACHER_H#define PROJECT5_TEACHER_H#include using namespace std;class Teacher {protected: string name; int age; string title;public: Teacher (string n, int a, string t); void display_teacher ();}; # endif / / PROJECT5_TEACHER_H

Teacher.cpp:

# include # include "Teacher.h" using namespace std;Teacher::Teacher (string n, int a, string t): name (n), age (a), title (t) {} void Teacher::display_teacher () {cout
