【C++】基于STL演讲比赛流程管理系统

本文主要是介绍【C++】基于STL演讲比赛流程管理系统，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

一、比赛规则

学校举行一场演讲比塞，共有12个人参加。比赛共两轮，第一轮为淘汰赛，第二轮为决赛。每名选手都有对应的编号。如10001 ~10012。
比赛方式：分组比赛，每组6个人。
十个评委分别给每名选手打分，去除最高分和最低分，求的平均分为本轮选手的成绩当小组演讲完后，淘汰组内排名最后的三个选手，前三名晋级，进入下一轮的比赛。第二轮为决赛,前三名胜出。
每轮比赛过后需要显示晋级选手的信息。

二、比赛功能

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，用户按任意键后继续下一个阶段
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后缀名保存
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

[ 注意 ]：csv格式可以用excel或记事本方式打开。

三、全部代码

1. test.cpp

#include "Speecher.h"
#include "SpeechManager.h"
#include<iostream>
using namespace std;
int main()
{SpeechManager sm;sm.SpeechMeun();int choose = 0;srand((unsigned int)time(NULL));do{cout << "请输入：";cin >> choose;switch (choose){case 1:sm.StartSpeech();break;case 2:sm.ShowRecord();break;case 3:sm.ClearRecord();break;case 0:sm.ExitManager();break;default:cout << "输入有误，请重新输入" << endl;break;}} while (choose);return 0;
}

2. Speecher.h

#pragma once
#include<iostream>
#include<string>
using namespace std;
class Speecher
{
public:string name;double score[2];//两次分数：第一次为晋级分数，第二次为决赛分数
};

3. SpeecherManager.h

#pragma once
#include<iostream>
#include<string>
#include<vector>
#include<map>
#include <deque>
#include <algorithm>
#include <functional>
#include <numeric>
#include <fstream>
#include "Speecher.h"
using namespace std;
//演讲比赛管理类
class SpeechManager
{
public:SpeechManager();//构造~SpeechManager();//析构//菜单功能void SpeechMeun();//初始化void InitManager();//创建12位选手void CreatSpeaker();//开始比赛void StartSpeech(){//第一轮比赛//1.抽签this->SpeechDraw();//2.比赛this->SpeechContest();//3.公布晋级选手this->ShowScore();this->idex++;//1.抽签this->SpeechDraw();//2.比赛this->SpeechContest();//3.最终结果this->ShowScore();//4.最终结果保存在文件中this->SaveRecord();cout << "本届比赛完毕！" << endl;this->InitManager();this->CreatSpeaker();this->LoadRecord();}void SpeechDraw();//选手抽签void SpeechContest();//选手比赛void ShowScore();//晋级分数或决赛分数void SaveRecord();//保存决赛前三成绩void ShowRecord();//展示往届决赛成绩void LoadRecord();//读取往届成绩void ClearRecord();//清空数据void ExitManager();//退出vector<int> v1;//12个选手的编号vector<int> v2;//第一轮晋级选手的编号vector<int> victory;//胜利前三名选手的编号map<int, Speecher> m_speaker;//编号 和 对应的选手int idex;//比赛轮数bool FileIsEmpty;map<int, vector<string>> m_Record;//往届记录，包括：届数和每届冠军季军亚军
};
