C++与MFC结合以实现的餐厅桌号预订系统（基本功能有：1、 餐厅提供小，中，大三种餐位；2. 每种餐位若干，每个餐位都有相应的编号；）3. 每种餐位使用收取的费用不同； 4. 每位客人根据就餐人数选择不同类型的餐位，系统则根据等待人数给用户生成一个等待号码，显示客人当前排号以及在他之前有多少位客人在等待。 5. 不同类型餐位都有自己的一个等待列，为客人生成的号码互不影响； 6. 支持查询指定号码所在的餐位； 7. 实现日志功能（记录每天所有餐位的使用状况，收入）； 8．客人可以动态查看当前餐位使用情况（每种餐位当前排到多少号等） (C++ with MFC combined to realize the restaurant the table No. booking system (basic functions: 1, the restaurant offers a small, three seats 2 bits of each meal, each seating has a corresponding number ) each seating fees charged each guest to choose different types of seating dining number, wait for the number to the user-generated a waiting number the show guests Arranging and before him the number of The guests in the waiting. 5 different types of seats has its own a waiting column the guests generated numbers independently of each other 6.
