• 　　应用逻辑设计

1.　　灯类

a.　　主要属性和行为: 亮熄状态，关联图片资源对象，接受客户的亮熄要求

b.　　类CLight

成员变量: m_state

成员函数: init, getState, setState

2.　　开关类

a.　　主要属性和行为: 关联所控的电灯CLight，接受客户的按动操作

b.　　类CSwitch

成员变量: m_pLight

成员函数: init, push

3.　　实例对象： 两个开关，一个灯；

操作过程：点击界面按钮，响应点击事件，调用开关的成员函数push,从而点亮或熄灭电灯

• 　　注意：上述的逻辑代码写在一个头文件中，使用内联式实现其成员函数，并提交。-•　application logic design

1. Light class

A. the main attributes and behaviors: bright quenching condition, associated resource object images, accept the bright quenching requirements of our clients

B. class CLight

Member variables: m_state

A member function: init, getState, setState

2. Switch class

A. the main attributes and behaviors: correlation of the lights CLight, accept customer press operation

B. class CSwitch

Member variables: m_pLight

A member function: init, push

3. The instance objects: two switch, a lamp

Operation: click on the button, click event response, invoke the member function push switch, to light up or put out the light

. Note: the above logic code written in a header file, use inline type to achieve its member functions, and submit.
