简单介绍C++编程中派生类的析构函数

#include <iostream>
using namespace std;
class A{
public:
 A(){cout<<"A constructor"<<endl;}
 ~A(){cout<<"A destructor"<<endl;}
};
class B: public A{
public:
 B(){cout<<"B constructor"<<endl;}
 ~B(){cout<<"B destructor"<<endl;}
};
class C: public B{
public:
 C(){cout<<"C constructor"<<endl;}
 ~C(){cout<<"C destructor"<<endl;}
};
int main(){
 C test;
 return 0;
}

A constructor
B constructor
C constructor
C destructor
B destructor
A destructor
