Yup, correct. What I meant above with array[Length(array)] is for the languages that don't have it. Let me be more clear.

C/C++ doesn't have custom array indexes and as such <array[std::size(array) - 1]> is returning the last element of said array.

Delphi has custom array indexes and as such, taking your example with defining an array in the form <example_array : array[3..7] of integer>, I would not get the last element in case of <example_array[Length(example_array) - 1]. In this case I would have 2 options. Option 1 would be to use <High> function as in <example_array[High(example_array)]> to access example_array[7] element. Delphi also has <Low> function so you can iterate through a custom defined array by using <for> keyword with the help of them. Option 2 would be to actually build my own helper (this is the most wanted case when you're dealing with multi-dimensional arrays that also have custom indexes) and I would have something like <example_array.FromLastIndex(0)> to access example_array[7] element.

Hope this cleared the confusion.
