Question

How do I deallocate this type of 3D array in c++? I have a class that has a int*** volume as a member and I filled it this way..

    volume = new int**[xSize];
    for(int i =0; i<xSize; i++)
    {
        volume[i] = new int*[ySize];
        for(int j =0; j<ySize; j++)
        {
            volume[i][j] = new int[zSize];
            for(int k = 0; k<zSize;k++)
            {
                volume[i][j][k] = 0;
            }
        }
    }

Answer 1

You just reverse your actions (other than the filling of the array)

for(int i =0; i<xSize; i++)
{
    for(int j =0; j<ySize; j++)
    {
        delete[] volume[i][j];
    }
    delete[] volume[i];
}
delete[] volume;
