Question

What are the differences between an array of char pointers and a 2D array?

Answer 1

char* my_string[];

represents an array of strings.

int my_grid_of_ints[][];
char my_block_of_text[][];

If color = byte[3] then you could represent your screen monitor

color my_pixel_buffer[][] = new color[768][1024];

is a 2D array. As you can see, a 2D array can represent anything, including an array of char pointers (such as multiple lines of strings).
