C语言程序设计方案报告菜单源码测试.docx

一：系统功效
基础功效：
图书录入，删除，查找，和导入导出等。

图书属性：
书号，书名，第一作者，版次，出版年等。

菜单功效:
1. Input Records（输入若干条统计）
从键盘一次输入一本书信息，存放到结构体数组中，然后显示。提醒信息，确定是否输入下一条统计。
2. Display All Records（显示全部统计）
按次序显示全部统计，每屏显示10条统计，按<Enter>键继续显示下一屏。
3. Delete a Record（按书名查找，删除一本书）
输入待删除书书名，显示该书名全部书目，提醒输入待删除书目标书号，提醒是否删除，确定后，删除该书。
4. Sort（排序）
以书名为升序排列数组
5. Insert a record（插入一条统计）
以书名为序排列数组中插入一条统计，插入后，数组仍然有序。输出插入成功后信息。
6. Query（查找并显示一个统计）
输入书名，查找并显示包含该书名全部图书信息
7. Add Records from a Text File（从文件读入图书信息到结构体数组中）
用户可事先建立一个文本文件Dictory.txt。存放全部图书信息，文件格式以下：
2
1182 高等数学刘浩荣 5 同济大学出版社
7300 物理化学王德明 2 化学工业出版社

8. Write to a Text File
将数组中全部统计写入文件Records.txt中，要求格式和Dictory.txt相同。
0. Quit（退出图书管理系统）

新增加菜单功效：
9. Change a record
修改某一条统计值
a. Menu
显示菜单
b. Clear Screen
清屏
c. Pause
按暂停，按任意键继续

二：数据结构
Typedef struct
{
char ISBN[10];//书号
char book[30];//书名
char author[20];//作者
Int edition;//版本号
char press[50];//出版社名
int year;//出版年
}Bookinfo;

三：函数调用关系
Write_to_Text()
Display_main_menu()
Change_a_record()
Delete()
Sort_by_name()
Insert()
Insert_a_record()
AddfromText()
Delete_a_record()
Display()
Query()
Query_a_record()
Input()
main
