⚙️ C++ Compiler

📌 Description

This C++ Compiler is a modular compiler pipeline written primarily in C++. It simulates the internal architecture of modern compilers such as Clang by implementing:

• 🔎 Tokenization (Lexer)
• 🌳 Abstract Syntax Tree (AST)
• 🧠 Recursive Descent Parsing
• ⚡ Bytecode Instruction Generation
• 🖥️ Stack-Based Virtual Machine
