	cout << "1. 初始本金 100000 元，纯模拟炒股，无真实金钱交易\n";
	cout << "2. 系统自带4支默认股票，会随天数自动随机涨跌(-12%~+12%)\n";
	cout << "3. 只有大盘开盘状态下才能买卖股票、刷新每日股价；休市禁止一切交易\n\n";

	cout << "二、普通股民玩法（1-5功能）\n";
	cout << "1 查看市场行情：浏览全部股票代码、名称、现价、涨跌幅、是否停牌\n";
	cout << "2 买入股票：输入代码+数量，扣现金买入计入持仓\n";
	cout << "3 卖出股票：卖出持仓股票，资金原路返回可用余额\n";
	cout << "4 查看我的资产：显示现金、持仓个股、持仓均价、个股市值、总资产\n";
	cout << "5 更新股价：模拟新的一天到来，系统股自动随机波动\n\n";

	cout << "三、老板创业玩法（6-9开公司专属）\n";
	cout << "6 自己开公司：最低10万现金，开办手续费扣除5万；自定义股票代码、公司名、行业、初始股价(1-20)、总股本(1000-100000)；创建后自动持有自家公司50%股份上市交易\n";
	cout << "7 老板调控自家股票：仅能操作自己创立的公司，包含小幅拉升、小幅打压、发布利好大涨、发布利空暴跌；自建股票不会随每日自动波动，完全由你手动控盘\n";
	cout << "8 发放股东分红：自定义每股分红金额，所有持有该股票的股东均可获得现金分红\n";
	cout << "9 增发股票：增加公司总股本，可用于稀释股份、扩容上市\n\n";

	cout << "四、大盘全局控制（10号功能）\n";
	cout << "10 大盘开盘/休市：开盘后可交易、可刷新股价；休市停止买卖、停止股价刷新；也可对单只股票停牌复牌限制交易\n\n";

	cout << "五、游戏目标\n";
	cout << "普通玩家：低吸高抛交易系统股，积累总资产冲击千万上亿\n";
	cout << "老板玩家：创立上市公司，控盘股价吸引散户买入，靠分红、拉高套现赚取巨额资金\n";
