C++比赛打分流程系统

本程序通过C++实现成员创建和导入，流程管理，分数自动计算（并行），排名分数导出等功能。

通过定义类compareManager类实现以上功能。

compareManager.h

compareManager类的声明在compareManager.h中：

#pragma once
#include <iostream>
#include "competitor.h"
#include <vector>
#include <map>
#include <fstream>
#include <algorithm>
#include <functional>

//设计流程管理类
class compareManager

	~compareManager();

	void Show_Menu();

	void Design_Process(int choice);//程序流程人数、晋级人数获取以及算法的确定

	void createCompetitor();
	
	void import_Competitor();

	void Show_info();

	void Start_Competition();

	void Exit();

	void Competition_Draw();//抽签程序

	void Competition_Contest();//比赛进行程序

	void show_Score();

	int print_first_Num();

	//初始化容器属性
	void initCompetition();

	//第一轮

competitor.h

为了更好的管理选手的数据，又定义了一个competitor类，声明在competitor.h中：

#pragma once
#include <iostream>
#include <string>
using namespace std;

class Competitor
{
public:
	string class_;
	string category;
	string name;
	string song;
	double n_Score[2];
};

compareManager.cpp

compareManager类实现在compareManager.cpp文件中：

#include <fstream>
#include <string>
#include <deque>
using namespace std;

{
	//初始化容器和属性
	this->initCompetition();
}

compareManager::~compareManager()
