怎么找人做网站啊/自媒体营销方式有哪些

mutimap和map基本用法都是一样的，map中键值对中的键是唯一的，而mutimap中的键可以重复。mutimap在现实中也是很常用的，比如部门和员工的关系。mutimap和map的头文件都是

#include <iostream>
#include <map>
#include <string>
using namespace std;class Person
{
public:string m_name;int m_age;
};
int main()
{//部门和员工映射Person p1, p2, p3, p4, p5;p1.m_name = "张三";p1.m_age = 31;p2.m_name = "张四";p2.m_age = 32;p3.m_name = "张五";p3.m_age = 33;p4.m_name = "张六";p4.m_age = 34;p5.m_name = "张七";p5.m_age = 35;multimap<string, Person> mp;mp.insert(make_pair("销售部",p1));mp.insert(make_pair("销售部", p2));mp.insert(make_pair("开发部", p3));mp.insert(make_pair("开发部", p4));mp.insert(make_pair("财务部", p5));//查询开发部所有人员int num = mp.count("开发部");int i = 0;multimap<string, Person>::iterator iter_result = mp.find("开发部");while(iter_result != mp.end() && i<num){cout << iter_result->first << ":" << iter_result->second.m_name << endl;++iter_result;++i;}//查询开发部所有人员第二种方法，推荐使用这种方法auto begin = mp.lower_bound("开发部");auto end = mp.upper_bound("开发部");for (auto iter = begin; iter != end;++iter){cout << iter->first << ":" << iter->second.m_name << endl;}//给34岁以上的，名字后加一个 "+W“multimap<string, Person>::iterator iter = mp.begin();for (;iter != mp.end();++iter){if(iter->second.m_age >= 34){iter->second.m_name += "+W";}}cout << "结果为：" << endl;//遍历for (iter = mp.begin(); iter != mp.end(); ++iter){cout << iter->first << ":" << iter->second.m_name << endl;}system("pause");
