   allocating multidimensional arrays?
  i know how to create an multidimensional array, but not how to allocate it on the heap.[source langg = "cpp"]const int maxpoints = 250;const int maxpixels = 5;point* mousepoints = new point[maxpoints][maxpixels];obviusly dosent work.   
  You cannot allocate multidimensional arrays on the heap (because the first dimension should be fixed). You can use vectors-of-vectors or boost::multi_array in a much easier fashion.Also, technically, new allocates memory on the free store (the heap is where malloc gets its memory from).   ;  Check the comp.lang.c FAQ.int **array2 = malloc(nrows * sizeof(int *));array2[0] = malloc(nrows * ncolumns * sizeof(int));for(i = 1; i < nrows; i++)array2 = array2[0] + i * ncolumns;EDIT: Using "new" = C++ = use STL/Boost.
