C++STL容器案例-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 //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 //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 #include <iostream> #include <map> #include <vector> #include <string> #include <ctime> using namespace std; #define CEHUA 0 #define MEISHU 1 #define YANFA 2 class Worker { public: string m_Name; int m_Salary; }; void createWorker(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; //将员工放入到容器中 v.push_back(worker); } } //员工分组 void setGroup(vector<Worker>& v, multimap<int, Worker>& m) { for (vector<Worker>::iterator it = v.begin(); it != v.end(); ++it) { //产生随机部门编号 int deptId = rand() % 3; // 0 1 2 //将员工插入到分组中 //key部门编号， value具体员工 m.insert(make_pair(deptId, *it)); } } void showWorkerByGroup(multimap<int, Worker>& m) { cout << "策划部门" << 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 << " 姓名: " << pos->second.m_Name << " 工资： " << pos->second.m_Salary << endl; } cout << "-----------------------------" << endl; cout << "美术部门: " << endl; pos = m.find(MEISHU); count = m.count(MEISHU); index = 0; for (; pos != m.end() && index < count; pos++, index++) { cout << " 姓名: " << pos->second.m_Name << " 工资： " << pos->second.m_Salary << endl; } cout << "-----------------------------" << endl; cout << "研发部门: " << endl; pos = m.find(YANFA); count = m.count(YANFA); index = 0; for (; pos != m.end() && index < count; pos++, index++) { cout << " 姓名: " << pos->second.m_Name << " 工资： " << pos->second.m_Salary << endl; } } int main() { srand((unsigned int)time(NULL)); //1.创建员工 vector<Worker>vworker; createWorker(vworker); //2.员工分组 multimap<int, Worker>mworker; setGroup(vworker, mworker); //3.分组显示员工 showWorkerByGroup(mworker); return 0; } //当数据以键值对形式存在， 考虑用map或者multimap
