员工分组案例

案例描述：

• 公司今天招聘10个员工（ABCDEFGHIJ），10名员工进入公司之后，需要指派员工在哪个部门工作
• 公司信息有：姓名 工资组成；部门组成：策划、美术、研发
• 随机给10名员工分配部分和工资
• 荣国multimap进行信息插入，key（部门编号）value（员工）
• 分部门显示员工信息

代码：

#include<iostream>
using namespace std;
#include<map>
#include<string>
#include<vector>
#include<ctime>
#define CEHUA  0
#define MEISHU 1
#define YANFA  2


class Worker
{
public:

	/*Worker(string name, int salary)
	{
		this->m_Salary = salary;
		this->m_Name = name;
	}*/
	string m_Name;
	int m_Salary;
};

void CreateWorker(vector<Worker>& v)
{
	string nameSeed = "ABCDEFGHIJ";
	for (int i = 0;i < 10;i++)
	{
		Worker worker;
		worker.m_Name = "员工";
		worker.m_Name += nameSeed[i];

		worker.m_Salary = rand() % 10000 + 10000;  //10000~19999
		//将员工放入到容器
		v.push_back(worker);

	}
}

//员工分组
void setGroup(vector<Worker>& v, multimap<int, Worker>& m)
{
	for (vector<Worker>::iterator it = v.begin(); it != v.end();it ++ )
	{
		//产生随机部门编号
		int depId = rand() % 4;  // 0 1 2 3

		//将员工插入到分组中
		//key部门编号   value具体员工
		m.insert(make_pair(depId, *it));
	}
}

//分组显示员工
void ShowWorkerByGroup(multimap<int, Worker>& m)
{
	//0 A B C  1 D E G  3 F I...

	multimap<int,Worker>::iterator pos = m.find(CEHUA);
	int count = m.count(CEHUA);  //统计具体人数
	int index = 0;
