Explanation:

HCP : (Hexagonal closest packed)

CCP : (Cubic closest packed).

diff.b/w

The repeating structure of HCP has 2 layers of spheres whereas the repeating structure of CCP has 3 layers of spheres.

HCP layers cycle between two equivalent shifted layers in an ABABAB sequence.

CCP layers cycle among three different layers in an ABCABC sequence.
