Arrays like a cube... Possible or not?

Question

what do you think about this?
int sample[x][y][z]=
{
{x, x, x},
{y, y, y},
{z, z, z}
};

Answer 1

Yes it' possible

Answer 2

Actually, the example array you made is still only a 2D array. A 3D would be like this:

int sample[1][2][2] =
{
{{z, z}, {z, z}},
{{z, z}, {z, z}}
};

This is still possible.
