C++获取基类指针所指子类对象的类名

我们在程序中定义了一个基类，该基类有n个子类，为了方便，我们经常定义一个基类的指针数组，数组中的每一项指向都指向一个子类，那么在程序中我们如何判断这些基类指针是指向哪个子类呢？

关键字

typeid，有关此关键字的详细内容请自行百度。

代码：

 #include <iostream>
 #include <string>
 #include <typeinfo>
 using namespace std;

 class father
 {
 public:
     virtual void fun()
     {
         cout<<"this is father fun call\n";
     }
     virtual int id()
     {
         return ;
     }
 };

 class son1: public father
 {
 public:

     void fun()
     {
         cout<<"this is the son1 fun call\n";
     }

     int id()
     {
         return ;
     }

 };

 class son2: public father
 {
 public:

     void fun()
     {
         cout<<"this is the son2 fun call\n";
     }

     int id()
     {
         return ;
     }
 };

 int main()
 {
     father * pf;
     son1 s1;
     son2 s2;
     pf = &s1;
     cout << typeid(*pf).name() <<endl;
     string temp(typeid(*pf).name());
     if(temp == "class son1")
     {
         cout<<"this is son1\n";
     }
     else if(temp == "class son2")
     {
         cout<<"this is son2\n";
     }

     pf = &s2;
     cout << typeid(*pf).name() <<endl;
     string temp1(typeid(*pf).name());
     if(temp1 == "class son1")
     {
         cout<<"this is son1\n";
     }
     else if(temp1 == "class son2")
     {
         cout<<"this is son2\n";
     }
     return ;
 }
