架构师训练营第三周作业
发布于: 2020 年 06 月 24 日
1. 请在草稿纸上手写一个单例模式的实现代码,拍照提交作业。
2. 请用组合设计模式编写程序,打印输出图 1 的窗口,窗口组件的树结构如图 2 所示,打印输出示例参考图 3。
这是代码
#include <iostream>#include <string>#include <vector>using namespace std;class Component {public: Component(string type, string name) : _type(type), _name{name} {} virtual void draw(ostream &os) { os << "print " << _type << "(" << _name << ")" << endl; }private: string _type; string _name;};class Button : public Component {public: Button(string name) : Component("Button", name) {}};class Picture : public Component {public: Picture(string name) : Component("Picture", name) {}};class Label : public Component {public: Label(string name) : Component("Label", name) {}};class TextBox : public Component {public: TextBox(string name) : Component("TextBox", name) {}};class PasswordBox : public Component {public: PasswordBox(string name) : Component("PasswordBox", name) {}};class CheckBox : public Component {public: CheckBox(string name) : Component("CheckBox", name) {}};class LinkLable : public Component {public: LinkLable(string name) : Component("LinkLable", name) {}};class Composite : public Component {public: Composite(string type, string name) : _list{}, Component(type, name) {} virtual void draw(ostream &os) override { Component::draw(os); for (auto p : _list) { p->draw(os); } } void addComponent(Component *component) { _list.push_back(component); } ~Composite() { for (auto p : _list) { delete p; } }private: vector<Component*> _list;};class WinForm : public Composite {public: WinForm(string name) : Composite("WinForm", name) {}};class Frame : public Composite {public: Frame(string name) : Composite("Frame", name) {}};int main() { Composite* p_win = new WinForm("WINDOW窗口"); Composite* p_frame = new Frame("FRAME1"); p_win->addComponent(new Picture("LOGO图片")); p_win->addComponent(new Button("登录")); p_win->addComponent(new Button("注册")); p_win->addComponent(p_frame); p_frame->addComponent(new Label("用户名")); p_frame->addComponent(new TextBox("文本框")); p_frame->addComponent(new Label("密码")); p_frame->addComponent(new PasswordBox("密码框")); p_frame->addComponent(new CheckBox("复选框")); p_frame->addComponent(new TextBox("记住用户名")); p_frame->addComponent(new LinkLable("忘记密码")); p_win->draw(cout); delete p_win; return 0;}
这是输出结果
