Pass a dynamic array of objects to function

Question

I am in the process of learning c++. So i know a method by which you send something to function and then work as if it was call by value but actually it is call by reference

Answer 1

Using std::vector you can also do the following:

void list_cities(std::vector &cities)
{
    for (size_t iCity = 0; iCity < cities.size(); iCity++){
        cout << cities[iCity].get_name() << endl;
    }
}

std::vector cities;
// fill list here
list_cities(cities);
