c语言图书管理系统上机实验报告

1、 . . . 信息工程大学计算机系课程实验报告实验课程：C语言程序设计基础实验项目：图书管理系统指导教师：莉丽学生:学生学号：20100班 级：计算机科学与技术实验地点： 5201实验时间：2011 年 5 月 18 日实验成绩：评阅老师：一上机实验目的设计并实现该课程设计的目的主要在于：1) 对一定规模的综合软件编程有一定的经历与认识。在做的过程中，你会发现，提前的规划即分析与设计重要过编程过程，否则会走很多弯。2) 综合并结合现实应用使用C语言的知识。这个设计会用到C语言这门课的全部知识，其中以文件、数组与链表为主，书中提到的主要与重点算法都会使用到。3) 不仅涉与编程，还涉与到功能分析、

2、模块规划等方面的知识，这些知识在后续课程学习时，会经常使用。这些知识在学软件工程这门课时，会系统讲解。希望有了这次的经历，你能更好的体会软件工程这门课的意义，并能学好和用好其中的知识。4) 每项功能的实现，一般有多种方法，这里都强调使用时空效率最高的方法，此次实现只是让你有一个初步的认识，在下学期学习了数据结构后，你就知道为什么让你这样做，你也对数据结构这门课的作用与意义有所了解。二实验环境PC机每人1台三上机实验容编写图书管理系统,具有以下基本功能（1）    各种基本数据的录入。如：图书资料基本信息录入等。（2）   各种基本数据

3、的修改。即：允许对以与录入的数据重新进行编辑、修改。（3）    各种基本数据的插入。如：在图书采购信息中插入一条新信息等。（4）    各种基本数据的删除。如：假设某本书遗失且馆藏数为0，删除该书的相关信息等。（5）    基于各种数据的查询。如：书名中含有“计算机”的所有书籍、全部借出的所有图书等。（6）       基于各种基本数据的统计计算。四上机调试程序流程图（注：可打印）调用_window()函数,设置界
