Is a dynamic array automatically deallocated when it goes out of scope?

in this example

procedure foobar;
var tab:array of integer;
begin
  setlength(tab,10);
end;

is the array destroyed or the memory is leaking?

Why do you need to deallocate the dynamically allocated memory?

For dynamically allocated memory like “int *p = new int[10]”, it is programmers responsibility to deallocate memory when no longer needed. If programmer doesn't deallocate memory, it causes memory leak (memory is not deallocated until program terminates).

What happens if you dont delete dynamic array?

If you don't delete them, they will remain there (but won't be accessible -> this is called memory leak) until your process exits, when the operating system will deallocate them. Save this answer.

Are dynamically allocated arrays contiguous?

The right syntax for a dynamic array is int* arr = new int[5]; . Yes, it will be allocated contiguously.

The memory is freed. (That is, no memory leak!)
