———————类的继承———————
? 派生可以通过构造函数给基类的私有成员赋值
?类的继承格式(图片+代码段)
#include "iostream" using namespace std; class person { public: person(int a,int b):a(a),b(b) { cout << "person-build" << endl; } protected: int a; int b; }; class newperson:public::person { public: newperson(int a,int b):person(a,b) { cout << "newperson-build" << endl; } void showperson() { cout << this->a << endl; cout << this->b << endl; } void setpreson(int a,int b) { this->a=a; this->b=b; } }; int main() { newperson rlxy(10,20); rlxy.showperson(); rlxy.setpreson(50,60); rlxy.showperson(); }
?类只能继承基类的公有,保护成员,不能继承私有
?派生类的继承方式只会在多级继承的时候产生影响
?后面的博客会提到
