Ubuntu20配置Mysql常用操作

UML图

代码：

#include <iostream>
#include <list>
using namespace std;
 
 
class Target{
public:
    virtual void Request(){
        cout << "Target:普通请求" << endl;
    }
};
class Adaptee{
public:
    void SpecificRequest(){
        cout << "Adaptee:特殊请求" << endl;
    }
    ~Adaptee(){
        cout << "delete Adaptee" << endl;
    }
};
 
class Adapter:public Target
{
public:
    Adaptee *adaptee;
    Adapter(){
        adaptee = new Adaptee();
    }
    void Request(){
        adaptee->SpecificRequest();
    }
    ~Adapter(){
        cout << "delete Adapter" << endl;
        delete adaptee;
    }
};
 
int main(void){
    Target *t1 = new Target();
    t1->Request();
 
    Target *t2 = new Adapter();
    t2->Request();
    return 0;
}

结果

Target:普通请求
Adaptee:特殊请求
