C程序设计实习报告正文

1、第一章实习报告§ 1.1题目描述【要求】假定某民航机场共有 n个航班。每个航班有一航班号、确定的航线（起始站、终点站）、 确定的飞行时间（星期几）和一定的成员订额。试设计一民航订票系统，能提供下列服务。（1） 航班信息录入功能（航班信息用文件保存）。（2）航班信息浏览功能。（3）查询航线：（至少一种查询方式）。 按航班号查询。 按起点站查询。 按终点站查询。 按飞行时间查询。【提示】（1 ）需求分析航班信息用文件保存， 因而要提供文件的输入/输出功能；要浏览航班信息，需要提供显示功能；要查询航线，需要提供查找功能；另外，还要提供键盘式选择菜单以实现功能 选择。（2）总体设计整个系统可

2、以设计为航班信息输入模块、航班信息浏览模块和航线查询模块。（3）数据结构建立航班结构体，结构体成员包括航班号、起始站、终点站、飞行时间（星期几）、预售票总数、已售票数。§ 1.2算法设计根据需求分析，可以将这个系统的设计分为如下五大模块：输入航班信息，保存航班 信息，浏览航班信息，查找航班信息，退出。飞机订票系统输入航班信息浏览航班信息§ 1.3程序设计及代码分析1.结构体设计建立航班结构体，结构体成员包括航班号，起点站，终点站，飞行时间（星期几）,预售票 总数。struct air int fir_num;char start20;char term inu s20;ch
