Iterate through a C array

Question

I have an array of structs that I created somewhere in my program.

Later, I want to iterate through that, but I don\'t have the size of the array.

How can I

Answer 1

I think you should store the size somewhere.

The null-terminated-string kind of model for determining array length is a bad idea. For instance, getting the size of the array will be O(N) when it could very easily have been O(1) otherwise.

Having that said, a good solution might be glib's Arrays, they have the added advantage of expanding automatically if you need to add more items.

P.S. to be completely honest, I haven't used much of glib, but I think it's a (very) reputable library.
