 class cartp
{
public:
    virtual char* getcar()=0;
};

class BMW:public cartp
{
public:
    char* getcar()
    {
        return "BMW";
    }
};

class BENZ:public cartp
{
public:
    char* getcar()
    {
        return "BENZ";
    }
};

class carfactory
{
public:
    static cartp* getcarname(char* name)
    {
        if(strcmp(name,"BMW") == 0)
        {
            return new BMW();
        }
        else if(strcmp(name,"BENZ") == 0)
        {
            return new BENZ();
        }
        else
        {
            return NULL;

};
int main(int argc, char** argv)
{
    char name[20] = {0};
    char* car = name;
    cout<<"input cartype:";
    cin>>name;

    cartp* cc = carfactory::getcarname(car);
    cout<<"type is"<<cc->getcar()<<endl;
    return 0;
