#include 
using namespace std;

int
main(void)
{
    int layers = 3; // can be calculated in run-time
    int elem = 5; // can be calculated in run-time
    int* pArray = new int[layers * elem];
    /* usage */
    for (int i = 0; i < sizeof(pArray) / sizeof(pArray[0]); ++i) // traverse through layers
    {

        for (int j = 0; j < sizeof(pArray[0])/ sizeof(int); ++j) // traverse through elements in layer
        {
            // do some stuff
        }
    }
}
