通过本学习课程更进一步理解C++的基础知识和面向对象的思想。训练用系统的观点和软件开发一般规范进行软件开发，并在此过程中培养严谨的科学态度和良好的工作作风。初步掌握软件开发过程的问题分析、系统设计、程序编码、测试等基本方法和技能。熟练掌握C++中类及模板在程序中的应用，并熟练了解类中函数的调用。进一步提高上机动手能力，培养使用计算机解决实际问题的能力，为后继课程和毕业设计打下扎实的基础
2 课题题目
计算机辅助教学（CAI）软件开发：教小学生学英语。
3 设计要求
3.1 功能：
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(),#include 结构体、文件或数组）
3.2 要求：
1、用 C++语言实现程序设计；2、利用结构体数组实现信息的数据结构设计；3、系统的各个功能模块要求用函数的形式实现；4、界面友好（良好的人机交互），程序加必要的注释。
4 总体设计
设计分为两个主要的模块：管理员模块和学生端学习模块
4.1 管理员模块
主要负责：词汇的添加、修改、查找、删除，查看词库
4.2 学生端学习模块
主要是：答题
5 详细设计
5.1 管理员模块
5.1.1 密码登录
首次登录密码默认为空，所以直接进入管理界面。进入管理界面后通过修改密码的来设置管理员的密码，从而进行管理员权限的操作。为了能使密码下次登录有效就不可以写在磁盘中，需要写在文件或者数据库中，实现密码的读写。由于时间有限，经小组讨论，本程序采用文件存储词汇。
定义一个文件存account.txt储密码
#define FILENAME3 "account.txt"//存储密码
设置完密码，保存密码到account.txt，退出程序，再次登录则需要密码验证。
定义一个密码判断函数
string Judge_Acc();//判断密码
bool Judge_Pass=false;//判读之前是否登录成功
定义一个密码判断次数的函数
int Acc_Num=3;//次数判断
锁定判断函数
bool Acc_Flag = false;//锁定判断
当密码进行3次错误后，将直接进行账号锁定，无法再次登录
5.1.2 词汇的添加
定义一个词汇添加函数
void Add_Words();//添加
在词汇添加的操作中同密码一样需要把添加的词汇，保存到文件中。
定义一个文件存储词汇
#define FILENAME1 "words.txt"//存储词汇
确定词汇的添加方式
添加的形式以及一次添加个数
在添加时增加一个重复判断，如果单词已存在，则输出"已经存在此词汇，请重新输入…"
当添加完之前要添加的个数后，显示添加完成保存到”words.txt”，并询问是否要继续添加
5.1.3 词汇修改
定义一个词汇修改函数
void Mod_Words();//修改
选择修改词汇的方式
如果想直接根据词汇单词或者词意修改，可以选择1，再选择具体的操作选择是根据单词还是词意修改
1、修改单词 //根据单词英文查询修改2、修改词组 //根据汉语意思查询修改
如果检测到词库的没有的单词\词组，则输出查无此词汇，然后按任意键，
也可以选则2，直接打开词库，通过词汇的序号选择直接修改。
如果选择超出的序号则无法修改。再次重新选择序号，直至修改成功
5.1.4 词汇查找
定义一个词汇查找函数
void Que_Words();//查找
选择修改词汇的方式
如果检测到词库的没有的单词\词组，则输出查无此词汇，然后按任意键
5.1.5 词汇删除
定义一个词汇删除函数
void Del_Words();//删除
选择删除的方式
如果想直接根据词汇单词或者词意删除，可以选择1，再选择具体的操作选择是根据单词还是词意删除
如果检测到词库的没有的词汇，则输出查无此词汇，然后按任意键，输入y/n选择是否要重新删除
也可以选则2，直接打开词库，通过词汇的序号选择直接删除。
如果选择超出的序号则无法删除
5.1.6 查看词库
定义一个查看词库函数
void word::Show_Words()//显示
按照下表的格式显示词汇
5.2 学生端学习模块
5.2.1 答题
定义函数
void Start_Game();//开始学习
void Save_Game();//保存学习
void Ope_Game();//操作
void Menu_Game();//学习界
void Continue_Init();//获取等级
void random(int a[]);//随机函数
word **Grade_Words;//按等级存储词汇
void Init_Grade_Num();//数量
void Start_Game_Words(int a[]);//单词
void Start_Game_Mean(int a[]);//意思
int grade;//等级
创建一个保存等级的文件
#define FILENAME2 "grade.txt"//存储等级
设置答题升级过关的相关参数
#define object1 10//每一关的单词数量
#define object2 0.9//过关率 升级
#define object3 0.5//降级
开始答题
等级：1即第一关，第一关是随机单词，填写词意（每次只能填一个）
随机出题
答案提示
输入错误的答案
正确率大于90
50<=正确率<90
正确率小于50%
等级：2即第二关，第二关是随机词意，填写单词（每次只能填一个）
关卡设置
等级：3即第三关，第三关是随机单词或词意，填写单词或词意（每次只能填一个）
等级：4即第四关，第四关是随机词组，填写词意！（每次只能填一个）
等级：5即第五关，第五关是随机词组词意，填写词组！（每次只能填一个）
等级：6即第六关，第六关是随机词组或词意，填写词组或词意！（每次只能填一个）
5.3 附加音乐模块
音乐模块直接调用的第三方winmm库
//音乐的头文件
#include <mmsystem.h>
#pragma comment(lib,"winmm.lib")
在程序的一开始添加了背景BGM随机出题的时候触发题目弹出的clock音效当正确率低于90无法通关时发出call警告音效当正确率高于90，通关升级时发出cheer胜利的欢呼音效
6 调试分析
在调试时由于查看词库的代码的逻辑出现了bug，导致出现了无法查看词库内容和异常死循环，词库一直刷新的问题。解决方案：初始化以及错误打印输出报告，查看是否成功链入文件，并是否能对其读写
f.open(FILENAME1, ios::in | ios::out);if (!f.is_open()){cout << "文件打开失败..." << endl;return;}Init_Grade_Num();if (Grade_Num == 0){cout << "文件为空..." << endl;return;}
2.一开设计在词库删除时忘记设置词汇序号的减少导致，序号出现空缺的问题。
解决方案：删除词汇后，当前词汇后的单词全部在序号上减一
//全部移动for (int i = j; i < Num; i++){CE_Words[i] = CE_Words[i + 1];}//数量减一Num--;
由于使用的codeblocks在导入第三方winmm库时出现失败，因为是是第三方库不是codeblocks内置的库，需要手动添加。
解决方案：手动添加方法。
Setting → Compiler settings → Linker settings → 在link libraries中add自己第三方库即可。
