C++如何将地图复制到矢量

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

std::map<int, std::string> my_map;
my_map[1] = "one";
my_map[2] = "two";
my_map[3] = "three";

std::vector<std::pair<int, std::string>> my_vector;

for (const auto &entry : my_map) {
    my_vector.push_back(entry);
}

for (const auto &entry : my_vector) {
    std::cout << "Key: "<< entry.first << ", Value: "<< entry.second<< std::endl;
}
