缺点：创建类较多

适用：后期扩展较多，或比较复杂

#include<memory>#include<iostream>#include<string>#include<cctype>#include<algorithm>#include<cmath>#include<cstdio>using namespace std;enum Ctype {coreA,coreB};class SingleCore{public:    virtual void print(){        cout << "siglecore_print"<<endl;    }    ~SingleCore(){        cout <<"~~singlecore"<<endl;    }};class SingleCoreA :public SingleCore{public:    void print(){        cout << "A_print"<<endl;    }    ~SingleCoreA(){        cout <<"~~singlecoreA"<<endl;    }};class SingleCoreB :public SingleCore{public:    void print(){        cout << "B_print"<<endl;    }    ~SingleCoreB(){        cout <<"~~singlecoreB"<<endl;    }};class Factory{public:    virtual SingleCore* creatCore(){}};class FactoryA : public Factory{public:    SingleCoreA* creatCore (){        return new SingleCoreA;    }};class FactoryB : public Factory{public:    SingleCoreB* creatCore (){        return new SingleCoreB;    }};int main(int argc, char *argv[]){    auto_ptr<Factory> facA (new FactoryA() );    //facA->creatCore ()->print ();    auto_ptr<SingleCore> singA (facA->creatCore ());    singA->print ();    //auto_ptr<SingleCore> singcore (fac->creatCore (coreA) );    //singcore->print ();    return 0;}
