You asked "what is a cheat code?".
I explained to you in exhaustive detail what a "cheat code" is.
I will now go into even further more exhaustive detail in my answer since you still did not understand.
We are in a thread discussing a video game which is called "Parasite black".
As a video game, you play it on your computer.
In a single player video game, you might not want to spend your time grinding. So you want to cheat.
How then do you facilitate cheats?
Well, there is a place inside the game where you press a button. And you are then prompted to type in a "cheat code". This is a "code" that unlocks a specific "cheat".
cheat means an unfair advantage. in this case, letting you skip doing repetitive tasks.
"code" means "letters and numbers".
For example. In the famous video game "starcraft" by blizzard. If you typed "black sheep wall" it will reveal the entire map. eliminating the fog of war mechanic.
This is a cheat. which is enabled by the specific code "black sheep wall". put together it is a "cheat code".
There are many different codes, each doing a different thing.
