STL——案例-员工分组

公司今天招聘了10个员工（ABCDEFGHIJ），10名员工进入公司之后，需要指派员工在那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 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

#include<iostream>
#include<vector>
#include<map>
#include<string>
using namespace std;
class worker
{
public:
    string name;
    int salary;
};
void CreatePlayer(vector<worker> &a)
{
    char b[] = "ABCDEFGHIJ";
    int i = 0;
    for(;i<10;i++)
    {
        worker WORKER;
        WORKER.name = b[i];
        WORKER.salary = rand() % 5000 + 5000;
        a.push_back(WORKER);
    }
}
void MapWorker(vector<worker>&vec,multimap<int,worker>&mp)
{
    int ID;
    for (int i = 0; i < 10; i++)
    {
        pair<int, worker> temp;
        ID = rand() % 3;
        temp.first = ID;
        temp.second = vec[i];
        mp.insert(temp);
    }
​
}
void ShowWork(multimap<int, worker>& mp)
{
    //先输出编号为0的员工信息
    for (map<int, worker>::iterator begin = mp.begin(); begin != mp.end(); begin++)
    {
        if (begin->first == 0)
        {
            cout << "策划部" << "姓名" << begin->second.name << "工资" << begin->second.salary << endl;
        }
    }
    for (map<int, worker>::iterator begin = mp.begin(); begin != mp.end(); begin++)
    {
        if (begin->first == 1)
        {
            cout << "美术部" << "姓名" << begin->second.name << "工资" << begin->second.salary << endl;
        }
    }   for (map<int, worker>::iterator begin = mp.begin(); begin != mp.end(); begin++)
    {
        if (begin->first == 2)
        {
            cout << "研发部" << "姓名" << begin->second.name << "工资" << begin->second.salary << endl;
        }
    }
}
void test()
{
    //创建员工
    vector<worker> WORKERS;
    CreatePlayer(WORKERS);
​
    //员工分组
    multimap<int, worker> mWORKERS;
    MapWorker(WORKERS,mWORKERS);
​
    //分组显示员工
    ShowWork(mWORKERS);
}
int main()
{
    test();
    return 0;
}
