大家好，我是讯享网，很高兴认识大家。

简单工厂模式

属于类的创建型模型，又叫静态工厂方法模式。
定义一个类来负责创建其他类的实例，被创建的实例通常具有共同的父类。

#include<iostream> #include<string> using namespace std; //简单工厂模式： class Phone { 
    public: virtual void show_name() { 
    cout << "我是手机！\n\n"; } }; class iQOO_phone: public Phone { 
    public: virtual void show_name() { 
    cout << "我是iQOO手机！\n\n"; } }; class Vivo_phone: public Phone { 
    virtual void show_name() { 
    cout << "我是vivo手机！\n\n"; } }; class Factory { 
    public: Phone* creat(string name) { 
    if (name == "iQOO") { 
    cout << "开始生产iQOO手机！\n\n"; return new iQOO_phone; } if (name == "vivo") { 
    cout << "开始生产vivo手机！\n\n"; return new Vivo_phone; } else { 
    cout << "手机类型错误！已退出！\n\n"; return nullptr; } } }; int main() { 
    Factory *f = new Factory; Phone *p = f->creat("iQOO"); p->show_name(); return 0; }

工厂模式

每个工厂生产一类产品

讯享网#include<iostream> #include<string> using namespace std; //工厂模式： class Phone { 
    public: virtual void show_name() { 
    cout << "我是手机！\n\n"; } }; class iQOO_phone: public Phone { 
    public: virtual void show_name() { 
    cout << "我是iQOO手机！\n\n"; } }; class Vivo_phone: public Phone { 
    virtual void show_name() { 
    cout << "我是vivo手机！\n\n"; } }; class Factory_iQOO { 
    public: Phone* creat() { 
    cout << "开始生产iQOO手机！\n\n"; return new iQOO_phone; } }; class Factory_vivo { 
    public: Phone* creat() { 
    cout << "开始生产vivo手机！\n\n"; return new Vivo_phone; } }; int main() { 
    Factory_iQOO *iQOO = new Factory_iQOO; Phone *p = iQOO->creat(); p->show_name(); Factory_vivo *vivo = new Factory_vivo; p = vivo->creat(); p->show_name(); return 0; }
