四、课程设计摘要（中文）：
本次课程设计的主要目的是解决图书管理的相关问题，以便使复杂的图书管理工作
变得有序化，简单化。
全程序以 C 语言为主要操作语言，利用了 C 语言简洁紧凑、灵活方便，语法限制不
太严格，程序设计自由度大，生成目标代码质量高，程序执行效率高等方面的优点。在
编写代码的过程中运用到了指针类型（FILE *fp），结构体类型（struct books），数组
类型（int num[11]），字符串（char bname[21]）等类型，同时也调用了函数，如，input
函数，save 函数等，这样方便调用。也具有多种循环、条件语句控制程序流向，如，if
else 语句，while，do…while 语句,switch 和 for 语句等，从而使程序完全结构化。
完整的程序代码可以使达到以下功能：录入图书信息(input())，添加图书信息
(add())，删除图书信息(del())，修改图书信息(revise())，查找图书信息
(search())，保存图书信息到文件(save())，输出图书信息(output())，输出图书文件
信息(readfile())，退出系统(break)。并且，在任何一项功能中，都包含了基本信息
——图书书号（char num[20]），图书书名（char bname[40]），图书作者（char
wname[20]），图书出版社（char pubname[30]），出版时间（char pubtime[10]），图书
价格（float price）等。这些功能的具备可以满足图书管理的基本需求。

五、课程设计摘要（英文）：
The main purpose of course design to address issues related to library management, library
management in order to make the complex work has become orderly and simplified.
The whole program to C language as the main operating language, the use of C-simple compact,
flexible and convenient, grammatical constraints are less stringent, programming large degree of
freedom to generate high-quality object code, program implementation and high efficiency merits. In
the process of writing code applied to a pointer type (FILE * fp), structure type (struct books), array type
(int num [11]), string (char bname [21]) and other types, but also called functions, such as, input
function, save function, and so on, so easily invoked. Also has a variety of loop, conditional statements
control program flow, such as, if else statements, while, do ... while statements, switch and for
statements and so on, so that procedure is totally structured.
The complete code can achieve the following functions: input book information (input ()), add the
book information (add ()), remove the book information (del ()), modify the book information (revise ()),
find the book information ( search ()), save the book information to a file (save ()), the output book
information (output ()), the output book file information (readfile ()), exit the system (break). And, in any
one function, it would cover the basic information - Book ISBN (char num [20]), book title (char bname
[40]), book authors (char wname [20]), book publishing (char pubname [30]), published in time (char
pubtime [10]), book price (float price) and so on. These functions have to meet the basic needs of
library management.
