定义一个Person类,它的每个对象表示一个人。数据成员必须包含姓名、出生年份、死亡年份，一个构造函数，一析构函数，读取数据的成员函数，一个print()成员函数显示所有数据。

#include <iostream>
using namespace std;
class Person
{ public:Person(char* =0, int =0, int =0);~Person() { delete [] name; }char* name() { return name; }int born() { return yob; }int died() { return yod; }void print();private:int len;char* name;int yob, yod;
};void main()
{ Person cb("Charles Babbage",1792,1871);cb.print();
}Person::Person(char* name, int yob, int yod): len(strlen(name)), name(new char[len+1]), yob(yob), yod(yod)
{ memcpy(name, name, len+1);
}void Person::print()
{ cout << "\tName: " << name << endl;if (yob) cout << "\tBorn: " << yob << endl;if (yod) cout << "\tDied: " << yod << endl;
}
