(Not just C) where does the code of any language exist? Someone creates some lang.

First doubt- how.(its a question not a doubt)

- You can create you own language but you need to create one compiler/interpreter to understand that.

In which lang. Any?

- ofcourse any, but for that comipler needs to understand what the code means, if any one creates a language say english then compiler should understand english to convert it to Machine Code.

I think, after the lang is created, then the compiler/interpreter must be written. But how are the 2 linked?

- as said above compiler interpreter is needed to convert the High level language to Machine code.

How do the electrons behave in a way that they make the pixels darkened on screen (appearance of code), work according to our expectations????

- Every engineer knows that you must not be a exclusion. Whats the doubt

Compiler understands the lang. BUT who understands the compiler?

- compiler changes the HLL to LLL (Machine code). After that the machine understands that once invoked by loader.

HAVEN'T STUDIED COMPILERS YET.

- is it a Question? :-x if not please format it correctly
