案例-员工分组

#include<iostream>
using namespace std;

#include<map>
#include<vector>
#include<ctime>

//案例描述
//10名员工（ABCDEFGHIJ）进入公司之后，需要指派其在哪个部门工作
//员工信息有:姓名，工资；部门分为：策划，美术和研发
//随机给10名员工分配部门和工资
//通过multimap进行信息的插入，key（部门编号）value(员工)
//分部门显示员工信息

//实现步骤
//1.创建10名员工，放到vector中
//2.遍历vector容器，取出每个员工，进行随机分组
//3.分组后，将员工部门编号作为key，具体员工作为value，放入到multimap容器中
//4.分部门显示员工信息

#define MEISHU 2
#define YANFA 3
