继承的构造和析构顺序

程序示例

#include <iostream>
using namespace std;
class a
{
public:
    a(){cout<<"构造a"<<endl;}
    ~a(){cout<<"析构a"<<endl;}
};
class b
{
public:
    b(){cout<<"构造b"<<endl;}
    ~b(){cout<<"析构b"<<endl;}
};
class c
{
public:
    c(){cout<<"构造c"<<endl;}
    ~c(){cout<<"析构c"<<endl;}
};
class d
{
public:
    d(){cout<<"构造d"<<endl;}
    ~d(){cout<<"析构d"<<endl;}
};
class e
{
public:
    e(){cout<<"构造e"<<endl;}
    ~e(){cout<<"析构e"<<endl;}
};
class f:public a,public b,public c,public d,public e//构造和销毁类的顺序与此顺序有关
{};
void main()
{
    f a;
}
