c++超基础：继承的构造与析构（赋值兼容性原则）

一、概念



二、代码示例

#include <iostream>

using namespace std;

class Parent
{
protected:
const char *Name;
public:
Parent()
{
Name = "Parent";
}
void print()
{
cout<<"Name: "<<Name<<endl;
}
};

class Child:public Parent
{
protected:
int i;
public:
Child(int i)
{
this->i = i;
Name = "Child";
}
};

int main(int argc, char *argv[])
{
Child child(100);
Parent parent = child;
Parent *pp = &child;
Parent &rp = child;

parent.print();
pp->print();
rp.print();

return 0;
}
