How do C / C ++ parsers work?

Question

I spent a lot of time learning the work of the PHP parser:

it translates the PHP code finally into code.

But how is c-code translated into executable files?

By the way, how can one judge whether language A can be converted to language B in some way from the mathematical aspect?

Answer 1

This is a really big and very deep question, which draws on many parts of computer science.
