迭代std-containers中的所有元素对(C++)

#include<iostream>
#include<vector>
#include <utility>

int main() {
    std::vector<std::pair<int, int>> my_vector = {{1, 2}, {3, 4}, {5, 6}};

    for (const auto& element_pair : my_vector) {
        std::cout << "First element: "<< element_pair.first << ", Second element: "<< element_pair.second<< std::endl;
    }

    return 0;
}
