准备

1.在VS中新建一个项目-Viscal C++ ---常规--空项目

2.建立一个.h的头文件 定义一个类 声明其成员(C#中的属性和方法)

#include
     
      #include
      
       using namespace std;class Person{public:    void setId(int id);    int getId();    void setName(string name);    string getName();    void setAge(int age);    int getAge();private:    int _id;    string _name;    int _age;};
      
     

建立一个.cpp的文件  声明一个类 实现成员变量初始化操作

#include "Per.h";using namespace std;void Person::setId(int id){    this->_id = id;}void Person::setName(string name){    this->_name = name;}void Person::setAge(int age){    this->_age= age;}int Person::getId(){    return this->_id;}string Person::getName(){    return this->_name;}int Person::getAge(){    return this->_age;}int main(){    }

 

通过对象方式

Person Per;    Per.setId(1);    Per.setAge(25);    Per.setName("Tony");        int id = Per.getId();    string name = Per.getName();    int age = Per.getAge();         cout << id <<","<< name <<","<< age<

 

通过指针方式

Person *Per = new Person();

Per->setId(1);

Per->setName("Tommy");

Per->setAge(20);

int id = Per->getId();

string name = Per->getName();

int age = Per->getAge();

cout << id <<","<< name <<","<< age<<endl;

delete Per;

system("pause");

return 0;

完成代码例子

#include "Per.h";using namespace std;void Person::setId(int id){    this->_id = id;}void Person::setName(string name){    this->_name = name;}void Person::setAge(int age){    this->_age= age;}int Person::getId(){    return this->_id;}string Person::getName(){    return this->_name;}int Person::getAge(){    return this->_age;}int main(){    //1.通过对象方式访问    //Person Per;    //Per.setId(1);    //Per.setAge(25);    //Per.setName("Tony");        //int id = Per.getId();    //string name = Per.getName();    //int age = Per.getAge();    //2.通过指针方式访问    Person *Per = new Person();    Per->setId(1);    Per->setName("Tommy");    Per->setAge(20);    int id = Per->getId();    string name = Per->getName();    int age = Per->getAge();     cout << id <<","<< name <<","<< age<
