Classes

After writing the program it shows me Punct3D: [-1.1;2.2;3.3]
Sfera: [[0;0;0];4.1], instead of showing me instead of Punct3D: [-1.1;2.2;3.3] Sfera: [[-1.1;2.2;3.3];4.1], can you explain me where i did wrong?

Your constructor for Sfera doesn't do anything with the Punct3D object you pass in by value.
