演讲比赛系统

1.需求分析

学校举行一场比赛，共有12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。
第一轮分为两个小组，整体按照选手的编号进行抽签后顺序演讲。
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名选手，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。

2.程序和功能

程序	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，用户按任意键进入下一个阶段。
查看往届记录	查看之前比赛的前三名，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	将文件中的数据清空。
退出比赛程序	可以退出程序。

3.程序逻辑

3.1建立演讲比赛管理类

	void SaveRecord();
	//初始化
	void InitSpeech();
	//判断文件是否为空
	bool File_Is_Empty;
	//往届数据的容器
	map<int, vector<string>>M_Record;
	~Speech_Manager();
	void CreatSpeaker();
	string CreatName(int a);
	void ShowScore();
	void Wait_Revolution();
	//往届记录
	void ShowRecord();
	//清空记录
	void ClearRecord();
	//读取记录
	void LoadRecod();
	//创建轮数
	int Revolution;
	//第一轮比赛人员编号
	vector<int>v1;
	//第二轮比赛人数编号
	vector<int>v2;
	//获胜人编号
	vector<int>vVictory;
	//存放编号和对应具体选手的容器
	map<int, Speaker>M_Speker;
	//存放届数
};

3.2开始演讲比赛程序

比赛流程分析：

抽签—>开始第一轮演讲比赛—>显示第一轮比赛结果—>抽签—>开始第二论比赛—>

显示前三名结果—>保存分数。

void Speech_Manager::SpeechConst()
{
	
	cout << "----------------第" << this->Revolution << "轮比赛开始-----------------" << endl;
	multimap<double, int, greater<double>>GroupScore;
	int num = 0;
	vector<int>V_class="lazy" data-src;//参赛容器
	if (this->Revolution == 1)
	{
		V_class="lazy" data-src = v1;
	}
	else
	{
		V_class="lazy" data-src = v2;
	}
	//遍历选手
	for (vector<int>::iterator it = V_class="lazy" data-src.begin(); it != V_class="lazy" data-src.end(); it++)
	{
		num++;
		deque<double>d;
		for (int i = 0; i < 10; i++)
		{
			double score = (rand() % 401 + 600) / 10.f;
			d.push_back(score);
		}
			sort(d.begin(), d.end(), greater<double>());//降序排列
			d.pop_front();
			d.pop_back();
			double sum = accumulate(d.begin(), d.end(), 0.0f);
			double average = sum / (double)d.size();//平均分
			//将平均分放入到map容器当中
			this->M_Speker[*it].M_Score[this->Revolution - 1] = average;
			GroupScore.insert(make_pair(average, *it));
			if (num % 6 == 0)
			{
				cout << "第" << num / 6 << "小组比赛名次如下：" << endl;
				for (multimap<double, int, greater<double>>::iterator it = GroupScore.begin(); it != GroupScore.end(); it++)
				{
					cout << "编号：" << it->second << "姓名：" << this->M_Speker[it->second].M_Name
						<< "成绩：" << this->M_Speker[it->second].M_Score[this->Revolution - 1] << endl;
				}
				int count = 0;
				for (multimap<double, int, greater<double>>::iterator it = GroupScore.begin(); it != GroupScore.end()&&count<3; it++,count++)
				{
					if (this->Revolution == 1)
					{
						v2.push_back((*it).second);
					}
					else
					{
						vVictory.push_back((*it).second);
					}
				}
				GroupScore.clear();
				cout << endl;
			}
		}
		cout << "-------------第" << this->Revolution << "轮比赛结束-------------" << endl;
	system("pause");
}
void Speech_Manager::ShowScore()
{
	cout << "-------------第" << this->Revolution << "轮晋级选手信息如下：----------" << endl;
	vector<int>v;
	if (this->Revolution == 1)
	{
		v = v2;
	}
	else
	{
		v = vVictory;
	}
	for (vector<int>::iterator it = v.begin(); it != v.end(); it++)
	{
		cout << "选手编号：" << *it << "性别：" << this->M_Speker[*it].M_Sex << "姓名：" << this->M_Speker[*it].M_Name
			<< "得分：" << this->M_Speker[*it].M_Score[this->Revolution - 1] << endl;
	}
	cout << endl;
	system("pause");
	system("cls");
	this->ShowmMenu();
}

3.3查看往届比赛结果程序

void Speech_Manager::ShowRecord()
{
	if (this->File_Is_Empty)
	{
		cout << "显示失败！文件为空或者不存在！";
	}
	else
	{ 
		for (int i = 0; i < this->M_Record.size(); i++)
		{
			//cout << this->M_Record.size();
			cout << "第" << i + 1 << "届比赛结果如下：" << endl;
			cout << "冠军编号：" << this->M_Record[i][0] << "\t"<<"   姓名:" << this->M_Record[i][1] 
				<< "\t" <<"性别：" <<this->M_Record[i][2] << "\t" <<"得分："<< this->M_Record[i][3] <<endl;
			cout << "亚军编号：" << this->M_Record[i][4] << "\t" << "   姓名:" << this->M_Record[i][5]
				<< "\t" << "性别：" << this->M_Record[i][6] << "\t" << "得分：" << this->M_Record[i][7] << endl;
			cout << "季军编号：" << this->M_Record[i][8] << "\t" << "   姓名:" << this->M_Record[i][9]
				<< "\t" << "性别：" << this->M_Record[i][10] << "\t" << "得分：" << this->M_Record[i][11] << endl;
		}
	}
	system("pause");
	system("cls");
}

3.4清空记录

void Speech_Manager::ClearRecord()
{
	cout << "是否清空文件记录" << endl;
	cout << "1.确定" << endl;
	cout << "2.否认" << endl;
	int select = 0;
	cin >> select;
	if (select == 1)
	{
		//确认清空
		ofstream ofs("File_Name.txt",ios::trunc);
		ofs.close();
		this->InitSpeech();
		this->CreatSpeaker();
		//加载往届记录
		this->LoadRecod();
		cout << "清空成功" << endl;
	}
	system("pause");
	system("cls");
	}

3.5等待程序和随机产生姓名程序

oid Speech_Manager::Wait_Revolution()
{
	for (int i = 0; i < 3; i++)
{
	cout << "Wait ";
	for (int j = 0; j < 3; j++)
	{
		Sleep(1500);
		cout << " * ";
	}
	system("cls");
	cout << "正在抽签，请等待" << endl;
}
}
string Speech_Manager::CreatName(int a)//a随机次数，a不同导致不同结果。
{
	string name;
	string NA1[] = { "赵", "钱", "孙", "李", "周", "吴", "郑", "王", "冯", "陈", "褚", "卫", "蒋" };
	string NA2[] = { "伟", "刚", "勇", "毅", "俊", "峰","秀", "娟", "英", "华", "慧" };
	srand((unsigned int)(time)(NULL));
	for (int i = 0; i < a; i++)
	{
		name = NA1[rand() % (sizeof(NA1) / sizeof(NA1[0]))];
		name += NA2[rand() % (sizeof(NA2) / sizeof(NA2[0]))];
	}
	return name;
}
