Error : Invalid pointer access

[Arnab Karmakar]

      CArrayDouble *in[], *out[];
      CArrayDouble *inTest[], *outTest[];
      ArrayResize(in, ArraySize(dataArr));
      ArrayResize(out, ArraySize(dataArr));
      for(int i = 0 ; i < ArraySize(dataArr); i++) {
         for(int j = 0 ; j < 9; j++) {
            in[i].Add(dataArr[i][j]);       
         }
         out[i].Add(dataArr[i][9]);       
      }

Can anybody guide me why I am getting Invalid pointer access error at

in[i].Add(dataArr[i][j]);

and

out[i].Add(dataArr[i][9]);

Thanks

Arnab
