功能介绍
speechManager.h函数包含演讲比赛流程的所有功能如下:
开始演讲比赛:完成整届比赛的流程,每个比赛阶段需要给用户一个提示,用户按任意键进入下一个比赛阶段
查看往届记录:查看之前比赛前三名结果,每次比赛都会记录到文件中,文件用.csv后缀保存
清空比赛记录:将文件中数据清空
退出比赛程序:可以退出当前程序
//构造函数

//菜单功能
void show_Menu();
//退出系统
void exitSystem();
//析构
~SpeechManager();
//创建12名选手
void creatSpeaker();
//开始比赛 比赛流程的控制函数
void startSpeech();
//抽签
void speechDraw();
//比赛函数
void speechContest();
//显示得分
void showScore();
//保存分数
void saveScore();
//读取往届信息
void loadRecord();
//文件为空标志位
bool fileIsEmpty;
//往届记录

分析类图:
Speaker类创建选手,选手信息包括姓名、得分
变量名 | 变量类型 | 范围 | 描述 |
m_Name | string | - | 选手姓名 |
m_Score | double | 0-100 | 选手得分 |
SpeechManager类
变量名 | 变量类型 | 范围 | 描述 |
v1 | vector<int> | - | 保存第一轮选手编号的容器 |
v2 | vector<int> | - | 保存第二轮选手编号的容器 |
vVictory | vector<int> | - | 保存前三名选手编号容器 |
m_Index | int | - | 存放比赛轮数 |
m_Record | map<int,vector<string>> | - | |
m_Speaker | map<int,Speaker> | - | 存放编号对应选手 |
fileIsEmpty | bool | - | 文件为空标志位 |
的字段v1、V2、vVictory用于分别对应存储:第一轮选手编号姓名和得分、第二轮编号姓名和得分、前三名选手编号姓名和得分 ;字段m_Index存储历史记录的届数,m_Record
