c++设计全国地区新冠感染人数统计系统

ps：承接上一篇通讯录管理系统的设计，模仿代码设计全国地区新冠感染人数统计系统

该系统主要包含的功能有：1、添加统计数据 2、显示统计数据 3、查找特定数据 4、修改统计数据 5、清空统计数据

查找功能分为三种方式：1、按地区查找；2、按日期查找；3、按地区+日期查找

1、程序主界面

2、添加统计数据
添加地区，时间，新增确诊人数，累计确诊人数，累计治愈人数，累计死亡人数。

3、显示统计数据

4、查找统计数据




5、修改统计数据

6、清空统计数据

#include

#include 

#define MAX 1000
#define number 20
using namespace std;

//设计统计类别结构体
struct Person
{
	//地区
	string m_regional;
	//日期
	string m_date;
	//新增确诊人数
	int m_raiseNumber;
	//累计确诊人数
	int m_totalNumber;
	//累计治愈人数
	int m_cureNumber;
	//累计死亡人数
	int m_deathNumber;
};
//设计全国地区+日期结构体

struct RegionalRecord
{
	//不同地区不同时间数组
	struct Person reg_day[MAX];  //地区，时间
	//记录统计地区和时间的数量
	int m_Number;
};

//1、添加统计信息
void addStatistics(RegionalRecord *re)
{
	//判断统计日期是否超过容量，如果超过将不再添加
	if (re->m_Number == MAX)
	{
		cout << "已满，容量无法添加" << endl;
		return;
	}
	else
	{

		//地区
		string regional;
		cout << "请输入地区：" << endl;
		cin >> regional;
		re->reg_day[re->m_Number].m_regional = regional;

		//时间
		string date;
		cout << "请输入时间: " << endl;
		cin >> date;
		re->reg_day[re->m_Number].m_date = date;

		//新增确诊人数

		re->m_Number++;

	}
}

//2、显示统计信息
void showStatistics(RegionalRecord *re)
{

	//如果不为0，显示记录的信息
	if (re->m_Number == 0)

//3.2、按日期查找
