C语言课程设计报告书教小学生学英语

1、C语言课程设计报告书教小学生学英语C语言程序设计课程设计报告设计题目：教小学生学英语专业 微电子学号 3130434063班级 132 班姓名 布玛利亚 .吾斯曼指导教师 张老师2013 年 秋季 学期设计任务：题目：计算机辅助教学( CAI )软件开发：教 小学生学英语 功能：1.屏幕上随机出现一个汉语单词， 英语 单词，汉语词组，英语词组或一短句提示小 学生给出相应答案，答错了要提示要求重新 输入，直到答对为止。要统计给分，且累计， 够一定分数后可进级，即从单词到词组，从 词组到短句。同样，也可降级。起步阶段可 各选 30 个，软件可扩充，即扩大词库的容量。( rand(),#includ
