2D arrays are arrays of arrays.

Example of a 2D array

[R,C]	0	1	2	3
0	[0,0]	[0,1]	[0,2]	[0,3]
1	[1,0]	[1,1]	[1,2]	[1,3]
2	[2,0]	[2,1]	[2,2]	[2,3]
3	[3,0]	[3,1]	[3,2]	[3,3]
The table shows a 2D array with the index’s on them. Below is the same table with data in the table.

	0	1	2	3
0	12	32	28	29
1	23	38	29	21
2	53	24	10	39
3	38	96	73	28
For example if we call:

Array[2,1]

We should get the following result.

24
