使用map迭代器反应创建简单对象的对象

#include <iostream>
#include <map>

int main() {
    std::map<std::string, int> myMap;

    // 添加键值对到map中
    myMap["key1"] = 1;
    myMap["key2"] = 2;
    myMap["key3"] = 3;

    // 使用map迭代器遍历map中的键值对
    for (auto it = myMap.begin(); it != myMap.end(); ++it) {
        std::cout << "Key: " << it->first << ", Value: " << it->second << std::endl;
    }

    return 0;
}
