How to pass array of structures to function in c++

Question

I need to pass array of structures to a function and I make it this way:
it's my function

void ShowRoutes(Route *routeList, int n, string title) { //... }

and it's function call

ShowRoutes(routeList, n, "Unsorted list: ");

but I would like to know are there other ways to pass array of structures to function?

I'd recommend std::array or std::vector, depending on when you know the size. — Qaz

I have just started learning C++, I don't know std::array or std::vector yet. — Heidel

They're typically easier to deal with than plain arrays (and especially dynamic arrays). They're a worthy investment. — Qaz

If you just started, you may as well learn some good practices now. It's worth the time. — StoryTeller - Unslander Monica

Instead of passing data around, encapsulate it and perform operations on it. — Open AI - Opting Out

Two ways I know of to pass arrays to functions.

The way you have it:

void ShowRoutes(Route *routeList, int n, string title) { //... }

or

void ShowRoutes(Route routeList[], int n, string title) { //... }

Either way you write the function, you would still call it the same way:

ShowRoutes(routeList, n, "Unsorted list: ");

But as others mentioned, would be a good idea to learn std::array and std::vector.
