1.案例——评委打分
案例描述
有五名选手，选手ABCDE,10个评委分别对每一个选手打分，去除最高分和最低分，取平均分。

#include<iostream>
#include<deque>
#include<vector>
#include<algorithm>
using namespace std;

class Person{
  public:
    string name;
    int score;
    Person(string name,int score):name(name),score(score){}

};

void setPerson(vector<Person>&v){
    string base_name = "ABCDE";
        for(int i=0;i<base_name.size();i++){
            string name = "选手"+string(1,base_name[i]);
            Person p(name, 0);
           v.push_back(p);
        }

    }

void setScore(vector<Person>&v){
    //如果不加引用，x只是v的副本
    for(auto &x:v){
        deque<int>q;
        for(int i=1;i<=10;i++){
            int score = rand()%41 + 60;
            q.push_back(score);
        }
        sort(q.begin(),q.end());
        q.pop_front();
        q.pop_back();
        int res = 0;
        for(auto c:q){
            res+=c;
        }
        cout<<res/q.size()<<endl;
       x.score = res/q.size();
    }

}

void PrintScore(vector<Person>&v){

    for(auto x:v){
        cout<<x.name<<" "<<x.score<<endl;
    }
}

int main(){

    vector<Person>v;
    setPerson(v);
    setScore(v);
    PrintScore(v);

    return 0;
}

2.案例——员工分组
案例描述
公司今天招聘了10个员工(ABCDEFGHIJ)，10名员工进入公司之后，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
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

#include<iostream>
#include<vector>
#include<map>
using namespace std;
#define cehua 0
#define donghua 1
#define itbumen 2
class worker{
    public:
        string name;
        double salary;
        worker(string name,double salary):name(name),salary(salary){}
};

void CreateWorker(vector<worker>&v){
    string base_name="ABCDEF";
    for(int i=0;i<base_name.size();i++){
        string name = "员工"+string(1,base_name[i]);
        double salary = rand()%10000 + 10000;
        v.push_back(worker(name,salary));
    }

}


void CreateGroup(vector<worker>&v,multimap<int,worker>&m){
    for(auto x:v){
        int id = rand()%3;
        m.insert(make_pair(id,x));
    }
    cout<<"策划组："<<endl;
    auto it = m.find(cehua);
    while(it!=m.end()&&it->first == cehua){
        cout<<it->second.name<<" "<<it->second.salary<<endl;
        it++;
    }
    cout<<"动画组："<<endl;
    it = m.find(donghua);
    while(it!=m.end()&&it->first == donghua){
        cout<<it->second.name<<" "<<it->second.salary<<endl;
         it++;
    }
    cout<<"it组："<<endl;
    it = m.find(itbumen);
    while(it!=m.end()&&it->first == itbumen){
         cout<<it->second.name<<" "<<it->second.salary<<endl;
         it++;
    }


}


int main(){
    vector<worker>v;
    multimap<int,worker>m;
    CreateWorker(v);
    CreateGroup(v,m);

    return 0;
}
