I may be wrong, but it seems (also from main's signature) you're trying to apply plain C point-of-view to a D feature (dyn array).
Also, maybe what you need is an array of strings?
Finally, to initialise a dynamic array at a given dimension, you may use the idiom
	string[] strings = new string[dim];
(but this does not work for 2 dimensions, I guess)
Sorry if I'm wrong and this does not help.
