一、主要功能

二、源程序

1.程序

#include<iostream>
#include<string>
using namespace std;
#include<vector>
#include<map>
#include<time.h>

#define CEHUA 0
#define MEISHU 1
#define YANFA 2

class Worker
{
public:
	string m_Name;
	int m_Salary;
};

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

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


	}
}
//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 deptID = rand() % 3;//0 1 2
		//将员工插入到分组中
		//key部门编号，value具体员工
		m.insert(make_pair(deptID, *it));
	}
}
void showWorkerByGroup(multimap<int,Worker>&m)
{
	//0 A B C   1 D E    2 F G……
	cout << "策划部门： " << endl;
	multimap<int, Worker>::iterator pos = m.find(CEHUA);
	int count = m.count(CEHUA);//统计具体人数
	int index = 0;
	for (; pos != m.end() && index < count; pos++, index++)
	{
		cout << "姓名： " << pos->second.m_Name << "工资： " << pos->second.m_Salary << endl;
	}
	cout << "----------------------" << endl;
	cout << "美术部门" << endl;
	pos = m.find(MEISHU);
	count = m.count(MEISHU);//统计具体人数
	index = 0;
	for (; pos != m.end() && index < count; pos++, index++)
	{
		cout << "姓名： " << pos->second.m_Name << "工资： " << pos->second.m_Salary << endl;
	}
	cout << "----------------------" << endl;
	cout << "研发部门" << endl;
	pos = m.find(YANFA);
	count = m.count(YANFA);//统计具体人数
	index = 0;
	for (; pos != m.end() && index < count; pos++, index++)
	{
		cout << "姓名： " << pos->second.m_Name << "工资： " << pos->second.m_Salary << endl;
	}

}
int main()
{
	srand((unsigned int)time(NULL));

	//1、创建员工
	vector<Worker>vWorker;
	createWorker(vWorker);
	//测试
	//for (vector<Worker>::iterator it = vWorker.begin(); it != vWorker.end(); it++)
	//{
	//	cout << "姓名： " << it->m_Name << "工资： " << it->m_Salary << endl;
	//}
	//2、员工分组
	multimap<int, Worker>mWorker;
	setGroup(vWorker, mWorker);
	//3、显示员工
	showWorkerByGroup(mWorker);


	system("pause");
	return 0;
}

2.功能界面

总结

综合使用了STL的容器，这里用到了vector,map容器的相关接口……
