作业二：拷贝构造函数

#include<iostream>using namespace std;class Person{public:    char* name;    int age;    Person():name("no name"),age(0)    {        cout<<"A person whose name is \""<<name<<"\" and age is "<<age<<" is created!"<<endl;    }    Person(char* n,int a):name(n),age(a)    {        cout<<"A person whose name is \""<<name<<"\" and age is "<<age<<" is created!"<<endl;    }    Person(const Person& p)//拷贝构造函数：    {        name=p.name;        age=p.age;        cout<<"A person whose name is \""<<name<<"\" and age is "<<age<<" is cloned!"<<endl;    }    ~Person()    {        cout<<"A person whose name is \""<<name<<"\" and age is "<<age<<" is erased!"<<endl;    }    void showPerson()    {        cout<<"This person is \""<<name<<"\" whose age is "<<age<<"."<<endl;    }    Person&  setName(char* n)    {        name=n;        return *this;    }    Person&  setAge(int a)    {        age=a;        return *this;    }};int main(){    int cases;    char str[80];    int age;    Person noname, Tom("Tom", 16), anotherTom(Tom);    cin>>cases;    for (int ca = 0; ca < cases; ca++)    {        cin>>str>>age;        Person newPerson(str, age);        newPerson.showPerson();    }    anotherTom.setName(str).setAge(18);    anotherTom.showPerson();    noname.showPerson();    return 0;}

Description

克隆技术飞速发展，克隆人已经成为现实了！！所以，现在由你来编写一个Person类，来模拟其中的克隆过程。这个类具有2个属性：name——姓名（char*类型），和age——年龄（int类型）。

该类具有无参构造函数（人名为“no name”，年龄是0）、带参数构造函数、拷贝构造函数以及析构函数外，还有以下3个成员函数：

1. void Person::showPerson()：按照指定格式显示人的信息。

2. Person& Person::setName(char *)：设定人的姓名。

3. Person& Person::setAge(int)：设定人的年龄。

Input

输入分多行，第一行是一个正整数N，表示其后有N行输入。每行分两部分：第一部分是一个没有空白符的字符串，表示一个人的姓名；第二部分是一个正整数，表示人的年龄。

Output

呃~比较复杂，见样例吧！注意：要根据样例编写相应函数中的输出语句，注意格式哦！

Sample Input

3
Zhang 20
Li 18
Zhao 99

Sample Output

A person whose name is "no name" and age is 0 is created!
A person whose name is "Tom" and age is 16 is created!
A person whose name is "Tom" and age is 16 is cloned!
A person whose name is "Zhang" and age is 20 is created!
This person is "Zhang" whose age is 20.
A person whose name is "Zhang" and age is 20 is erased!
A person whose name is "Li" and age is 18 is created!
This person is "Li" whose age is 18.
A person whose name is "Li" and age is 18 is erased!
A person whose name is "Zhao" and age is 99 is created!
This person is "Zhao" whose age is 99.
A person whose name is "Zhao" and age is 99 is erased!
This person is "Zhao" whose age is 18.
This person is "no name" whose age is 0.
A person whose name is "Zhao" and age is 18 is erased!
A person whose name is "Tom" and age is 16 is erased!
A person whose name is "no name" and age is 0 is erased!
