从vector继承的类

#include <iostream>
#include <cstdlib>
#include <cstring>
#include <vector>
using namespace std;


class AVP
{
private:
    char *name;
public:
    AVP()
    {
        name = NULL;
    }
    
    AVP(const char* _name)
    {
        name = new char[strlen(_name) + 1];
        strcpy(name, _name);
    }
    char* getName()
    {
        return name;
    }
};

class Read: public vector<AVP*>
{
public:
    bool startup()
    {
        AVP* a1 = new AVP("apple");        
        push_back(a1);
        a1 = new AVP("orange");        
        push_back(a1);
        a1 = new AVP("pear");        
        push_back(a1);
        
    }
    static Read* getInstance()
    {
        if(instance == NULL)
            instance = new Read();
        return instance;
    }
    void print()
    {
        iterator it = begin();
        for(; it != end(); ++it)
        {
            cout<<(*it)->getName()<<endl;
        }
        
    }
protected:
    Read()
    {
    }
private:
    static Read* instance;

};
Read* Read::instance = NULL;
int main()
{
    Read::getInstance()->startup();
    Read::getInstance()->print();
    
    
    return 0;
}

如果不理解Read类从public vecotr<AVP*>继承的话，可以这样，vector<AVP*> _avp; 

Read类从_avp继承,这样就很好理解了，直接看代码
