Multi-Dimensioning Dynamic Memory Management Class

[vanleurth]

Hi I'm new to Visual C++, previously I was able to write a function that dynamically allocate memory for multidimensional arrays [][][]. How can I define a class that will do the same job of returning a pointer to different memory space for different, for example;
*(int) - for a single dim
** (int) - for double dim
*** (int) - for triple dim

Do not use multidimensional indexing. You can, of course, allocate single-dimensional arrays for each row, then arrays of pointers for sets of rows, and so on. More simple is allocation of a single-dimensional array

p = new int[num_of_columns*num_of_rows];

and access elements through p[row*num_of_columns + column]

Sorry, you can simply define
int (*array_ptr)[3][4];
allocate
array_ptr=new(int[2][3][4]);
and access elements as
array_ptr[j][k]

Oh, that bloddy server...
