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!

注意:输出中有“”!
