如何从map<pair<string，int>，pair<string，Array>>中迭代和查找？

#include <iostream>
#include <map>
#include <string>
#include <array>

int main() {
    std::map<std::pair<std::string, int>, std::pair<std::string, std::array<int, 5>>> myMap;

    // 添加一些元素到map中
    myMap[std::make_pair("key1", 1)] = std::make_pair("value1", std::array<int, 5>{1, 2, 3, 4, 5});
    myMap[std::make_pair("key2", 2)] = std::make_pair("value2", std::array<int, 5>{6, 7, 8, 9, 10});
    myMap[std::make_pair("key3", 3)] = std::make_pair("value3", std::array<int, 5>{11, 12, 13, 14, 15});

    // 迭代map中的所有元素
    for (auto it = myMap.begin(); it != myMap.end(); ++it) {
        std::pair<std::string, int> key = it->first;
        std::pair<std::string, std::array<int, 5>> value = it->second;

        std::cout << "Key: (" << key.first << ", " << key.second << ")" << std::endl;
        std::cout << "Value: (" << value.first << ", [";
        for (int i = 0; i < value.second.size(); ++i) {
            std::cout << value.second[i];
            if (i != value.second.size() - 1) {
                std::cout << ", ";
            }
        }
        std::cout << "])" << std::endl;
    }

    // 查找特定的键值对
    std::pair<std::string, int> searchKey = std::make_pair("key2", 2);
    auto searchResult = myMap.find(searchKey);
    if (searchResult != myMap.end()) {
        std::pair<std::string, std::array<int, 5>> foundValue = searchResult->second;
        std::cout << "Found value: (" << foundValue.first << ", [";
        for (int i = 0; i < foundValue.second.size(); ++i) {
            std::cout << foundValue.second[i];
            if (i != foundValue.second.size() - 1) {
                std::cout << ", ";
            }
        }
        std::cout << "])" << std::endl;
    } else {
        std::cout << "Key not found." << std::endl;
    }

    return 0;
}
