#include ＜map＞应用

在看这篇文章之前，先看看#include <map>的简介。

#include ＜map＞https://blog.youkuaiyun.com/NOIP1ding_c/article/details/144293214这篇文章我来给大家一个map的应用。  

应用

#include <iostream>
#include <map>
#include <string>
int main() {
    // 创建一个 map 容器，存储员工的姓名和年龄
    std::map<std::string, int> employees;
    // 插入员工信息
    employees["Alice"] = 30;
    employees["Bob"] = 25;
    employees["Charlie"] = 35;
    // 遍历 map 并打印员工信息
    for (std::map<std::string, int>::iterator it = employees.begin(); it != employees.end(); ++it) {
        std::cout << it->first << " is " << it->second << " years old." << std::endl;
    }
    return 0;
}
