Why is Minecraft Windows 10 Edition or Pocket Edition called Bedrock Edition?

So I wanted to ask why is Minecraft Pocket Edition or Windows 10 Edition called Bedrock Edition? Why the name Bedrock? Why not Minecraft in C ++ version, because (as far as I know) it was programmed with C ++.

You have just come up with a name that fits all possible consoles and is easy to remember and say

Actually, it's not even called Bedrock Edition, just Minecraft.

That's true

idk lol u might think it's cuz it's made in the game engine bedrock but all editions of the game r made from bedrok
