¿Como funciona un compilador?

Answer 1

A compiler is a program that translates the source code for another program from a programing language into executable code.

The source code is typically in a high-level programming language (e. g. Pascal, C, C++, Java, Perl, C#, etc.). The executable code may be a sequence of machine instructions that can be executed by the CPU directly, or it may be an intermediate representation that is interpreted by a virtual machine (e. g. Java byte code).

In short, a compiler converts a program from a human-readable format into a machine-readable format.

As to how a compiler works, that is indeed complicated. There are books and university courses on the subject. I will attempt to briefly outline the main stages of the process, but this will be a very cursory overview.

Lexing - break up the text of the program into "tokens". The tokens are the "words" of the programming language, such as identifiers (keywords, variable names, function names, etc.) or operators (=, *, &, etc.).

Parsing - convert the sequence of to
