Sort of. Each cell can contain any data, much like a variable. The advantage of arrays, though, is that you have a mathematical way of calculating which cell you're manipulating, and can find associated information very easily. Think of 2D arrays as a spreadsheet of data, and imagine all the ways you could work with that data based on the concept of columns and rows.
ohh,i see.. thanks for describe it.
is there array for 3D? if yes,it will be very-very complex
