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

 运行结果如下：
