Corrections:
- 02:56 Capacity (not size) cannot be changed once static array is defined.

- 03:07 NULL is not considered an element. It's usually used to represent the absence of data. When counting the number of elements, null would typically not be included in the count.

- 21:57 Hexadecimal digits range is 0-F (0-9 or A-F).
