STL【四】
1、STL案例练习----员工分组
案例描述
- 公司今天招聘了10个员工(ABCDEFGHIJ),10名员工进入公司后,需要指派员工在哪个部门工作
- 员工信息有:姓名、工资组成;部门分为:策划、美术、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,
- 分部门显示员工信息
步骤实现
- 创建10名员工放到vector中
- 遍历vector容器,取出每个员工进行随机分组
- 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
- 分部门显示员工信息
代码实现
#include <iostream>
#include <map>
#include <vector>
#include <string>
#include <ctime>
using namespace std;
#define CEHUA 0
#define MEISHU 1
#define YANFA 2
class Worker

int m_salary;
};
void creatWorker(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;
v.push_back(worker);
}
}
void setGroup(vector<Worker>& v, multimap<int, Worker>& m)
{
for (vector<Worker>::iterator it = v.begin(); it != v.end(); it++)
{
int deptId = rand() % 3;
m.insert(make_pair(deptId, *it));
}
}
void showWorkerByGroup(multimap<int, Worker>& m)
{
cout << "策划部门信息:" << endl;
multimap<int, Worker>::iterator pos = m.find(CEHUA);
int count = m.count(CEHUA);
int index = 0;
for (; pos != m.end() && index < count; pos++,index++)
{
cout << "name:" << pos->second.m_name << " " << "salary:" << pos->second.m_salary << endl;
}
cout << endl;
cout << "***************************************" << endl;
cout << "美术部门信息:" << endl;
pos = m.find(MEISHU);
count = m.count(MEISHU);
index = 0
