3-26.txt

思路很清晰的c++课件。例子很简明

例3.26 对象作为类的数据成员

#include <iostream.h>
#include <string.h>

class string{
private:
	char *str;
public:
	string(char *s)
	{	str=new char[strlen(s)+1];
		strcpy(str,s);
		cout<<"构造string\n";
	}
	void print(){cout<<str<<endl;}
	~string()
	{ 	cout<<"析构string\n";
		delete str; 
	}
};

class girl{
private:
	string name;
	int age;
public:
	girl(char *st,int ag):name(st)
	{	age=ag;
		cout<<"构造girl\n";
	}
	void print()
	{	name.print();
	   	cout<<"age:"<<age<<endl;
	}
	~girl()
	{	cout<<"析构girl\n";
	}
};

void main()
{	girl  obj("Chen hao",25);
	obj.print();
}
