[C++知识库]入门级继承c++

有一大段代码，很多类都需要用到

难道你要每个类都写一遍吗？

想想就很繁琐

所以今天我们说一下继承

模板就

class 子类：（权限） 父类

大家可以看下面的代码了解一下

#include<iostream>
using namespace std;
class father
{
public:
	void head()
	{
		cout << "首页" << endl;
	}
	void back()
	{
		cout << "尾页" << endl;
	}
};
class son1 :public father
{
public:
	void content()
	{
		cout << "大儿子的页面" << endl;
	}
};
class son3 :public father
{
public:
	void content()
	{
		cout << "三儿子的页面" << endl;
	}
};
class son2 :public father
{
public:
	void content()
	{
		cout << "二儿子的页面" << endl;
	}
};
void test1()
{
	cout << "大儿子展示" << endl;
	son1 s1;
	s1.head();
	s1.back();
	s1.content();
	cout << "-----------------" << endl;
	cout << "二儿子展示" << endl;
	son2 s2;
	s2.head();
	s2.back();
	s2.content();
	cout << "-----------------" << endl;
	cout << "三儿子展示" << endl;
	son3 s3;
	s3.head();
	s3.back();
	s3.content();
	cout << "-----------------" << endl;
}
int main()
{
	test1();
	system("pause");
	return 0;
}

显然对于其中重复的

void head()
	{
		cout << "首页" << endl;
	}
	void back()
	{
		cout << "尾页" << endl;
	}

我们就只写了一次?
