How to insert multiple elements into a multi-dimensional array

Question

I'm modeling a chessboard and was wondering if there is a populate a multidimensional array using #new. I want each 'row' in the array to be initially populated with a '*' ie. [[ '*', '*', '*', '*', '*', '*', '*', '*'], [ '*', '*', '*', '*', '*', '*', '*', '*'], etc... ]

empty_frame = Array.new(8){[]}   #Can you use code block to fill here?

Or do i need to iterate through each 'row' to populate it?

You did the first level correctly using a block. Why not do the same with the second level?

empty_frame = Array.new(8){Array.new(8){"*"}}

or

empty_frame = Array.new(8){Array.new(8, "*")}

If you are doing destructive operations on the string, then you probably need the first form.
