2021.3.10C++实验课作业

从身边随便找一个物件，将其抽象为类，并实现这个类，具体要求如下:
（1）私有数据成员:
至少设计两个属性
（2）公有成员函数:
无参构造函数：将属性值置空
普通有参构造函数：通过参数给数据成员赋值
拷贝构造函数：通过一个已有对象初始化当前对象
析构函数：可以为空函数
输出：输出所有数据成员
（3）分文件存储类的声明和实现，新建cpp文件写主函数，并在主函数中测试类中所有成员函数。

Human.h

#include <cstdio>
#include <string>

using std::string;

class Human {
private:
	int height;//身高
	int weight;//体重
	string girlfriend;//npy
	string boyfriend;

public:
	//默认构造函数
	Human();
	//普通有参构造函数
	Human(int h, int w, string girl, string boy);
	//拷贝构造函数
	Human(const Human& xxx);

	//析构函数
	~Human();
	//输出函数
	void print();

	void setHeight(int height);
	void setWeight(int weight);
	void setGirlfriend(string girlfriend);
	void setBoyfriend(string boyfriend);

	int getHeight() const;
	int getWeight() const;
	string getGirlfriend() const;
	string getBoyfriend() const;
};
