如何在C++中创建元组的向量？

#include <iostream>
#include <vector>
#include <tuple>

int main() {
    // 创建一个元组的向量
    std::vector<std::tuple<int, std::string, double>> vec;

    // 向向量中添加元组
    vec.push_back(std::make_tuple(1, "apple", 2.99));
    vec.push_back(std::make_tuple(2, "banana", 1.99));
    vec.push_back(std::make_tuple(3, "orange", 0.99));

    // 遍历向量中的元组并输出
    for (const auto& tuple : vec) {
        int id;
        std::string name;
        double price;
        std::tie(id, name, price) = tuple;
        std::cout << "ID: " << id << ", Name: " << name << ", Price: " << price << std::endl;
    }

    return 0;
}
