STL案例vector容器,map容器综合题目

一级标题 STL案例vector容器,map容器综合题目

案例描述
公司招聘十个员工(ABCDEFGHIJ),十名员工进入公司之后,需要指派员工在哪个部门工作。
员工信息有:姓名 公资组成 ;部门分为:策划,美术,研发。
随机给十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
创造十名员工,放到vector中
遍历vector容器,取出每个员工,进行随机分配
分组后,将员工部门编号作为key,具体员工作为value,放到multimap容器中
分部门显示员工信息

#include<iostream>
using namespace std;
#include<vector>
#include<string>
#include<map>
#include<ctime>

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

class Worker

//创建员工
void creatWorker(vector<Worker>& v)

	string nameSeed = "ABCDEFGHIJ";

		worker.m_Nmae += nameSeed[i];

		worker.m_Salary = rand() % 10000 + 10000;

		v.push_back(worker);
	}

// 2.分组

		//将员工查到分组中
		//key 部门编号,value 具体值

//3.分组显示员工

	//3.分组显示员工
	showWorkerByGroup(mWorker);
