从用户定义的函数返回多个值

def get_user_info():
    name = "Alice"
    age = 30
    return name, age  # 返回一个元组

user_name, user_age = get_user_info()
print(user_name, user_age)

function getUserInfo() {
    return { name: "Alice", age: 30 }; // 返回一个对象
}

const userInfo = getUserInfo();
console.log(userInfo.name, userInfo.age);

#include <iostream>

std::tuple<std::string, int> getUserInfo() {
    return std::make_tuple("Alice", 30); // 返回一个元组
}

int main() {
    auto [name, age] = getUserInfo();
    std::cout << name << " " << age << std::endl;
    return 0;
}
