话不多说 先上图

 

三天时间照着课本打出来的~略有改进。

实训答辩能保证运行操作稳过。

底层模块调用链表读模块与链表写模块，各模块内部运行多以链表来实现。

整个系统核心思想为组建多个模块，以模块调用的形式构成整个系统。

（类似于搭积木）

目前我本人做的三界面基本完善，但是有以下几点希望后继者帮忙改进：

程序在进入增删改等底层界面操作完成后或者误入时，可以按任意键返回

结合实际，增加完善经理界面的功能

程序模块结构如下：

1.台桌界面功能选项

void addtab();void delettab();voidaltertab();void looktab();void alltab();

2.人员界面功能选项

void addstaff();voiddeletstaff();void alterstaff();void lookstaff();

void allstaff();

3.菜目界面功能选项

void adddish();voiddeletdish();void alterdish();void lookdish();

void alldish();

4.服务员可操作的功能选项

void seeorder();void seedish();voidpayoff();void starttab();

void startdish();void seetab();

5.经理操作功能项

void dishcharge();voidtabcharge();void staffcharge();

6.主管操作功能项

void countsell();

7.三种账户开始界面及初始化与登录界面

voidmanagerinter();void serverinter();void chargeinter();

voiduserenter();void systementer();

重点来了！代码部分！
