C++之Person类 - 技术栈

首先设置头文件，将题目中的要求完成。

cpp 复制代码

#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。

cpp 复制代码

#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。

cpp 复制代码

#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;
}
