单片机模拟交通灯显示。其中，红灯与绿灯显示时间均为50s，中间的黄灯显示时间为15s。绿灯用八位发光二极管流动闪烁作代表；红灯用八位发光二极管全亮作代表；黄灯用八位发光二极管全亮全灭闪烁作代表。刚开始显示的为绿灯。(SCM simulated traffic light display. Among them, the red and green display times are 50s, in the middle of the yellow light is displayed for 15s. Green with eight light-emitting diode flashes as a representative flow red with eight full brightness light-emitting diodes as a representative yellow with eight light-emitting diodes for all light flashes Quanmie representatives.

说明：  ACE自适配通信环境（ADAPTIVE Communication Environment）是可以自由使用、开放源码的面向对象（OO）框架（Framework），在其中实现了许多用于并发通信软件的核心模式。ACE提供了一组丰富的可复用C++ Wrapper Facade（包装外观）和框架组件，可跨越多种平台完成通用的通信软件任务，其中包括：事件多路分离和事件处理器分派、信号处理、服务初始化、进程间通信、共享内存管理、消息路由、分布式服务动态（重）配置、并发执行和同步，等等。(Ace adaptive communication environment is a free-to-use, open-source object-oriented (OO) framework, in which many core patterns for concurrent communication software are implemented. Ace provides a rich set of reusable C + + wrappers Facade and framework components can complete common communication software tasks across multiple platforms, including event multiplexing and event processor dispatch, signal processing, service initialization, inter process communication, shared memory management, message routing, dynamic (RE) configuration of distributed services, concurrent execution and synchronization, etc.)

编写一个程序实现小型公司的人员信息管理系统。该公司雇员（employee）包括经理（manager），技术人员（technician）、销售员（salesman）和销售部经理（salesmanager）。要求存储这些人员的姓名、编号、级别、当月薪水，计算月薪并显示全部信息。 程序要对所有人员有提升级别的功能。为简单起见，所有人员的初始级别均为1，然后进行升级，经理升为4级，技术人员和销售部经理升为3级，销售员仍为1级。 月薪计算办法是：经理拿固定月薪8000元，技术人员按每小时100元领取月薪，销售员按该当月销售额4 提成，销售经理既拿固定月工资也领取销售提成，固定月工资为5000元，销售提成为所管辖部门当月销售额的5‰。 (Write a program to implement the personnel information management system of small company. The company employees (employee) including managers (manager), technical personnel (technician), salesman (salesman) and the sales manager (salesmanager). For store the personnel s name, serial number, level, monthly salary, calculate monthly salary and display all the information. Program for all personnel have the function of level. For the sake of simplicity, all staff of the initial level 1, and then upgrade, manager promoted to level 4, technicians and sales manager for level 3, the salesperson is still the 1st level. Monthly salary calculation way is: managers with a fixed monthly salary of 8000 yuan, technicians receive monthly salary 100 yuan per hour, the salesman make the monthly sales 4 commission, sales manager with both fixed monthly salary also receive sales commissions, fixed monthly salary of 5000 yuan, sales to become the jurisdiction of the department of sales that month 5 ‰.)

说明：  一款让人意想不到的好策略黄金刷单修改版EA根据市场行情波动这款策略能抓住70%以上行情，是一款不可思议的刷单EA，黄金刷单是一款对空对冲策略直观的感觉是，不仅单量多盈利也强，动态止损止盈的全自动交易策略，主要基于黄金，利用顺势多空微马丁策略可做刷单与返佣，无论是跑货币还是黄金刷单都是一款非常不错的好策略，平均月盈利在20%左右。结合有对冲机制，在振荡行情下会进行多空对冲，在趋势行情下则会直接止损错误单子，顺应单边趋势，所以该策略无论单边行情还是振荡行情都能适用。(An unexpected good strategy, the modified version of EA, can capture more than 70% of the market according to market fluctuations. It is an incredible EA, and the intuitive feeling of gold brushing is that it is an air hedging strategy. It is not only profitable but also strong, and the automatic trading strategy of dynamic stop loss and profit is mainly based on gold. Using the homeopathic long and short micro Martin strategy can do brushing and rebates. Whether it is running money or gold brushing is a very good strategy, on average, Combined with hedging mechanism, long and short hedging will be carried out in oscillating market, while wrong orders will be stopped directly in trend market, which conforms to unilateral trend, so this strategy can be applied in both unilateral market and oscillating market.)
