[c++]容器类。继承类的构造和析构

#include<iostream>using namespace std;class Base{int x;public:Base(int a){x = a;cout<<"father constructing "<<x<<endl;}~Base(){cout<<"father destructing "<<x<<endl;}};class Dervied:public Base{int y;Base B2,B1;//只与定义顺序有关public:Dervied(int a = 0,int b = 0,int c = 0,int d = 0):B1(d),Base(b),B2(c),y(a)//与参数列表的顺序无关{cout<<"son constructing "<<y<<endl;}~Dervied(){cout<<"son destructing "<<y<<endl;}};int main(){Dervied(1,2,3,4);return 0;}
