macOS objective c and arrays

[kashmoney2006]

I am trying to create a tic tac toe program in xcode using objective c in an attempt to learn the language. i was wondering if objective c supports 2-D arrays? that is hove i implemented it in previous languanges but cant figure it out in ObjC. in c++ i used something similar to

 int board[][]

is this possible in ObjC?

It's standard C syntax. If you want to get fancy I think the NSArray class would be your other option.

NSMutableArray is an object. You can make an NSArray or NSMutableArray of them, if you want to. Those can be arrays of NSNumbers that you store something in. I wouldn't, though.

I don't know what you want to store, exactly, but I think a single dimension array should suffice for this purpose. If you are having a 3x3 array to store board state, i'd say just use a 9 element array. I'd say just have them be chars. Ints are SO big, after all. You can save *27* bytes assuming 32 bit ints. Then you can store 'X','O', or ' '(or '\0' if you prefer).

I am, of course, being facetious. If you really want to be a glutton for punishment, you should store the board state in a single short(2-byte) integer.

int board [][]

while not work either in C++ or in C or in Objective-C.

int board [10][10] works in all three languages.
