C++ 类的 this 指针 语法练习

 

#include <iostream>#include <string>using namespace std;// 定义一个类 Studentclass Student{private:string name;int    age;string address;public:// 存void setname(string s){name = s;}void setage(int y){age = y;}void setaddress(string add){address = add;}    // 取string getname(){return name;}int getage(){return age;}string getaddress(){return address;}void Show(){ cout<<"this = "<<this<<endl;}protected:};int main(void){   Student x;     x.Show();   cout<<"&x   = "<<&x<<endl;     // 以上表明this指向的就是当前的对象x   cout<<"----------------------"<<endl;   Student y;   y.Show();   cout<<"&y   = "<<&y<<endl;      // 以上表明this指向的就是当前的对象y// --------------------return 0;}

第一次调用时,this地址与对象x的一样;

第二次调用是,this地址与对象y的一样.
