思路很清晰的c++课件。例子很简明

例4.7 派生类的构造函数与析构函数的执行顺序

#include <iostream.h>

class base{
public:
	base(){cout<<"Construction base class.\n";}
	~base(){cout<<"Destruction base class.\n";}
};

class derive:public base{
public:
	derive(){cout<<"Construction derived class.\n";}
	~derive(){cout<<"Destruction derived class.\n";}
};

void main()
{
	derive op;
}
