Problem C: 克隆人来了！

Posted 2020-09-04 TogetherLaugh

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!

HINT

注意：输出中有“”！

Append Code

#include<iostream>

#include<string.h>

using namespace std;

class Person

{

private:

    string name;

    int age;

public:

    Person(){name="no name",age=0;cout<<"A person whose name is \""<<name<<"\" and age is "<<age<<" is created!\n";}

    Person(string n,int a){name=n,age=a;cout<<"A person whose name is \""<<name<<"\" and age is "<<age<<" is created!\n";}

    void showPerson(){cout<<"This person is \""<<name<<"\" whose age is "<<age<<".\n";}

    Person& setName(string m){name=m;}

    Person& setAge(int a){age=a;}

    Person(const Person &Tom){name=Tom.name,age=Tom.age;cout<<"A person whose name is \""<<name<<"\" and age is "<<age<<" is cloned!\n";}

    ~Person(){cout<<"A person whose name is \""<<name<<"\" and age is "<<age<<" is erased!\n";}

};

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;

}
