STL实例——员工分组

    科技2022-07-12  136

    案例描述:

    招聘10个员工,入职后,需要指派员工在哪个部门工作;

    员工信息:姓名,工资;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;

    思路:

    创建10名员工,放到vector中;遍历vector,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,具体员工为value,放到multimap中;分部门显示员工信息; #include<iostream> #include<algorithm> #include<map> #include<vector> #include<string> #include<ctime> #define CH 0//策划部门 #define MS 1//美术部门 #define YF 2//研发部门 using namespace std; class Person { public: string m_Name; int m_Wage; }; void creatWorker(vector<Person>&v) { string name = "ABCEEFGHIJ"; for (int i = 0; i < 10;i++) { Person p; p.m_Name = "员工"; p.m_Name += name[i]; p.m_Wage = rand() % 10000 + 10000; v.push_back(p); } } void setGroup(vector<Person>&v, multimap<int, Person>&m) { for (vector<Person>::iterator it = v.begin(); it != v.end(); it++) {//遍历每个人分组 //产生随机本门编号 int depId = rand() % 3;//0 1 2 //将员工插入到分组中 m.insert(make_pair(depId, *it)); } } void show(multimap<int, Person>&m) { cout << "策划部门:" << endl; multimap<int, Person>::iterator pos = m.find(CH);//查找第一个出现的位置 int count = m.count(CH);//统计 int index = 0; for (; pos != m.end() && index < count; pos++,index++) { cout << "姓名:" << pos->second.m_Name << "工资:" << pos->second.m_Wage << endl; } cout << "美术部门:" << endl; pos = m.find(MS); count = m.count(MS); index = 0; for (; pos != m.end() && index < count; pos++, index++) { cout << "姓名:" << pos->second.m_Name << "工资:" << pos->second.m_Wage << endl; } cout << "研发部门:" << endl; pos = m.find(YF); count = m.count(YF); index = 0; for (; pos != m.end() && index < count; pos++, index++) { cout << "姓名:" << pos->second.m_Name << "工资:" << pos->second.m_Wage << endl; } } void test() { //利用系统时间做一个真实的随机 srand((unsigned int)time(NULL)); //创建员工 vector<Person>v; creatWorker(v); /*测试代码 for (vector<Person>::iterator it = v.begin(); it != v.end(); it++) { cout << it->m_Name << " 工资:" << it->m_Wage << endl; } cout << endl;*/ //员工分组 multimap<int, Person>m; setGroup(v,m); //分组显示 show(m); } int main() { test(); system("pause"); return 0; }
