C++类的多重继承演示

news 2024/11/8 6:32:32

一个派生类可以继承多个基类

以下代码演示派生类zzj继承两个基类people、student

#include <iostream>using namespace std;class people
{
private:int m_age;
public:people(int age);void print();~people();
};people::people(int age)
{cout << "people 构造" << endl;m_age = age;
}void people::print()
{cout << "年龄：" << m_age << endl;
}people::~people()
{cout << "people 析构" << endl;
}class student
{
private:int m_score;
public:student(int score);void print();~student();
};student::student(int score)
{cout << "student 构造" << endl;m_score = score;
}void student::print()
{cout << "分数：" << m_score << endl;
}student::~student()
{cout << "student 析构" << endl;
}class zzj : public people, public student
{
private:string m_name;
public:zzj(int age, int score, string name);void print();~zzj();
};zzj::zzj(int age, int score, string name) : people(age), student(score)
{cout << "zzj 构造" << endl;m_name = name;
}void zzj::print()
{people::print();student::print();cout << "姓名：" << m_name << endl;
};zzj::~zzj()
{cout << "zzj 析构" << endl;
}int main()
{zzj z(19, 98, "ZZJ");z.print();return 0;
}

需要注意75、76行在调用两个基类print函数时出现了两个基类成员函数重名

需要加上类名和域解析符::来区分
