首先设置头文件，将题目中的要求完成。

#include <iostream>using namespace std;class Person
{
public:Person();Person(string name, int id, string address);~Person();void setPerson(string name, int id, string address);void setName(string name);void setID(int id);void setAddress(string address);string getName();int getID();string getAddress();void print(); // outPutResult
private:string Name;int ID;string Address;
};

完成各个功能函数在另一个cpp中。

#include "Person.h"using namespace std;Person::Person()
{Name = "S.M.Wang";ID = 070145;Address = "莲花路200号";
}Person::Person(string name, int id, string address)
{setPerson(name, id, address);
}Person::~Person()
{cout << "object Destructor is called" << endl;
}void Person::setPerson(string name, int id, string address)
{Name = name;ID = id;Address = address;
}void Person::setName(string name)
{Name = name;
}void Person::setID(int id)
{ID = id;
}void Person::setAddress(string address)
{Address = address;
}string Person::getName()
{return Name;
}int Person::getID()
{return ID;
}string Person::getAddress()
{return Address;
}void Person::print()
{cout << "姓名:" << getName() << endl;cout << "ID:" << getID() << endl;cout << "住址:" << getAddress() << endl;
}

最后在main调用，先设定和初始化类再执行public函数。

#include <iostream>
#include "Person.h"
using namespace std;int main()
{Person myPerson;// Person myPerson("S.M.Wang", 070145, "莲花路200号");cout << "请输入姓名:" ;string name;cin >> name;cout << "请输入ID:" ;int id;cin >> id;cout << "请输入住址:" ;string address;cin >> address;myPerson.setName(name);myPerson.setID(id);myPerson.setAddress(address);myPerson.print();return 0;
}
