4. 小学数学出题系统 概述 为小学生教学服务能够根据小学生的需要随机抽出两位数的数学运算题可根据需要进行加减乘除运算。由学生在电脑上答题并对其判断正误和记分。另外可以根据需要随机抽出四则运算的混合运算题同样应对其判断正误和记分。 基本要求 抽题选择功能 两位数四则与算的出题功能 四则混合运算的抽题功能 答案判断正误功能 分数累积功能 出题存储功能等 课程设计基本思路 建立一个或多个结构体代表不同的复杂数据类型。 利用结构体数组来暂时存储要进行操作的数据 通过把结构体数组元素存到文件里的形式完成对数据的永久存储。 一般操作流程为 如对某个记录进行操作 1. 先把所有数据从文件中调入到一个结构体数组中暂时存储 2. 再通过指针运算或数组运算对数组中的某些记录进行操作和赋值。 3. 最终结束操作后把改变过的结构体数组再存到文件中保存起来
1、 尽量多的应用C语言中所学到的知识和语句 2、 课程设计前应书写开题报告主要内容包括对题目的分析和对该课程设计的概要设计 3、 课程设计后应交《课程设计报告》和软件原代码及编译后的应用软件 4、 课程设计最后一次上机实验时检查题目的完成情况 5、 课程设计中必须用到的内容为 a) 文件的存取 b) 结构体的使用 c) 数组的使用 d) 指针操作
