Compiler

A compiler is a special program that translates computer code written in one programming language (the source language) into another language (the target language), often a low-level language like machine code, bytecode, or assembly code. Its primary function is to transform human-readable source code, which is typically complex and expressive, into a format that a computer's processor can directly understand and execute. This translation process involves several stages, including lexical analysis, parsing, semantic analysis, and code generation, ensuring the original program's logic is preserved.
