找到一种方法将匹配的键和值从映射转换为向量( push_back

#include <iostream>
#include <map>
#include <vector>

int main() {
    std::map<std::string, std::string> myMap;
    myMap["key1"] = "value1";
    myMap["key2"] = "value2";
    myMap["key3"] = "value3";

    std::vector<std::pair<std::string, std::string>> myVector;

    for (const auto& pair : myMap) {
        myVector.push_back(pair);
    }

    // 打印向量中的键值对
    for (const auto& pair : myVector) {
        std::cout << "Key: " << pair.first << ", Value: " << pair.second << std::endl;
    }

    return 0;
}
