while writing code i got a question. For example i created a class named as unit.

Think a simple game, and the unit class will belong the units.

İf i give the preferences as private one by one, it will be irregular. For a detailed game; height, weight, race, hair preferences, eyes... Strength, dexterity, charisma, intelligence, wisdom, constution... experience, damage, armor...
and should i use struct to group them? And how to can i use struct at the inside of class as private? Can u give me examples.
Thank you.
