继承的定义和好处

#include
#include
using namespace std;
//继承
//继承的好处:可以减少重复的代码
class basepage {
public:
	void header() {
		cout << "首页，公开课，登录" << endl;
	}
	void footer() {
		cout << "帮助中心，交流中心，站内地图" << endl;
	}

		cout << "java python c++" << endl;
	}
};
//java类
class java :public basepage {
public:
	void centent() {
		cout << "java学习视频" << endl;
		cout << "_________________" << endl;
	}
};//继承语法class 子类:继承范围 父类
//子类又叫派生类，父类又叫基类
