What is the size of these tables?

How did you decide the length of the field to store the carriers name?

Can you propose a more compact version of your data structures?

Which functions can you think that can be implemented with the information in these tables? (either processing them separately or both at the same time).

Let us suppose that each data structure with their functions are in separated files. A third file is added in which only the main function is defined, but it uses all the functions and the data structures previously defined. Which information must be included before the main definition?
