1、类图
2、源代码 test4.cpp #include<iostream> #include<string> using namespace std; //抽象产品类 男人 class Man { public: virtual void makeM() = 0; }; //具体产品类 白色男人 class WhiteMan : public Man { public: void makeM() { cout << "我是白种男人"<< endl; } }; //具体产品类 黄色男人 class YellowMan : public Man { public: void makeM() { cout << "我是黄种男人" << endl; } }; //具体产品类 黑色男人 class BlackMan : public Man { public: void makeM() { cout << "我是黑种男人" << endl; } }; //抽象产品类 女人 class Woman { public: virtual void makeW() = 0; }; //具体产品类 白色女人 class WhiteWoman : public Woman { public: void makeW() { cout << "我是白种女人" << endl; } }; //具体产品类 黄色女人 class YellowWoman : public Woman { public: void makeW() { cout << "我是黄种女人" << endl; } }; //具体产品类 黑色女人 class BlackWoman : public Woman { public: void makeW() { cout << "我是黑种女人" << endl; } }; //抽象工厂类 肤色 class Color { public: virtual Man *produceMan() = 0; virtual Woman *produceWoman() = 0; }; //具体工厂类 黄色 class Yellow : public Color { public: Man *produceMan() { return new YellowMan(); } Woman *produceWoman() { return new YellowWoman(); } }; //具体工厂类 白色 class White : public Color { public: Man* produceMan() { return new WhiteMan(); } Woman *produceWoman() { return new WhiteWoman(); } }; //具体工厂类 黑色 class Black : public Color { public: Man * produceMan() { return new BlackMan(); } Woman * produceWoman() { return new BlackWoman(); } }; //主函数 int main(int argc, char*argv[]) { Color * color_y = new Yellow(); Man * man_y = color_y->produceMan(); Woman * woman_y = color_y->produceWoman(); Color * color_b = new Black(); Man * man_b = color_b->produceMan(); Woman * woman_b = color_b->produceWoman(); Color * color_w = new White(); Man * man_w = color_w->produceMan(); Woman * woman_w = color_w->produceWoman(); string t ; string y = "Yellow"; string b = "Black"; string w = "White"; string e = "exit"; while (strcmp(t.c_str(), e.c_str()) != 0) { cout << "请输入标识符 ( 首字母大写 )："; cin >> t; if (strcmp(t.c_str(), y.c_str()) == 0) { man_y->makeM(); woman_y->makeW(); } else if (strcmp(t.c_str(), w.c_str()) == 0) { man_w->makeM(); woman_w->makeW(); } else if (strcmp(t.c_str(), b.c_str()) == 0) { man_b->makeM(); woman_b->makeW(); } else if (strcmp(t.c_str(), e.c_str()) == 0) { //输入exit退出系统 cout << "退出" << endl; } else { cout << "输入的标识符有误，请重新输入！" << endl; } cout << endl; } if (man_y != NULL) { delete man_y; man_y = NULL; } if (woman_y != NULL) { delete woman_y; woman_y = NULL; } if (man_b != NULL) { delete man_b; man_b = NULL; } if (woman_b != NULL) { delete woman_b; woman_b = NULL; } if (man_w != NULL) { delete man_w; man_w = NULL; } if (woman_w != NULL) { delete woman_w; woman_w = NULL; } } 3、遇到的问题 3.1 指针使用不正确，应如如下代码 //抽象工厂类 肤色 class Color { public: virtual Man *produceMan() = 0; virtual Woman *produceWoman() = 0; }; 3.2 字符串初始化报错 string t = NULL; 标签：woman,string,10.28,c++,软件设计,str,NULL,color,man From： https://www.cnblogs.com/kongxiangzeng/p/18658655
