C++语法小记---继承中的构造和析构顺序

继承中构造和析构的顺序

• 先父母，后客人，最后自己

• 静态变量和全局变量在最开始

• 析构和构造的顺序完全相反

 #include <iostream>
 #include <string>

 using namespace std;

 class Global
 {
 public:
     Global()
     {
         cout<< "Global()" << endl;
     }

     ~Global()
     {
         cout<< "~Global()" << endl;
     }
 };

 class Other
 {
 public:
     Other()
     {
         cout<< "Other()" << endl;
     }

     ~Other()
     {
         cout<< "~Other()" << endl;
     }
 };

 class Parent
 {
 public:
     Parent()
     {
         cout<< "Parent()" << endl;
     }

     ~Parent()
     {
         cout<< "~Parent()" << endl;
     }
 };

 class Child : public Parent
 {
     Other other;
 public:
     Child()
     {
         cout<< "Child()" << endl;
     }

     ~Child()
     {
         cout<< "~Child()" << endl;
     }
 };

 Global gobal;

 int main()
 {
     Child c;    //构造顺序 Global() Parent() Other() Child()
                 //析构顺序 ~Global() ~Child()  Other() Parent() 

     return ;
