Question

char *createBoard( ){  
  char          


        

Answer 1

This approach will not work. If you return a pointer to a local variable you'll run into undefined behaviour. Instead allocate an array on heap with new and copy data into it manually indexing it.

Answer 2

I would really recommend using STL vector<> or boost/multi_array containers for this.

If you must use arrays, then I would recommend using a typedef to define the array.

typedef char[16][10] TBoard;

You could also return

 char**

...but then you would need to typecast it to the correct size in order to index it correctly. C++ does not support dynamic multiple dimension arrays.

Also as others have suggested you can't return an object on the stack (i.e., local variable)
