C-- Compiler in C

A lightweight compiler for a simplified C-like language, built from scratch in C.
This project demonstrates core compiler construction concepts including lexical analysis, parsing, syntax validation, and translation toward lower-level output.

Overview

This project was developed to explore the main phases of compilation by implementing a small compiler for the C-- language. The compiler processes source input, performs tokenization and parsing, and reports syntax-related issues with line-aware diagnostics.

Features

• Lexical analysis using a custom scanner
• Parsing for C-- language constructs
• Error reporting with line-number tracking
• Driver programs for testing scanner and parser behavior
• Makefile-based build process

Project Structure

• scanner.c / scanner.h — lexical analyzer implementation
• parser.c / parser.h — parser implementation
• driver.c — main compiler driver
• scanner-driver.c — standalone scanner testing
• Makefile — build automation
• test.c, test2.c, exmpl.txt — sample input files
• out.txt, diff.txt — output / comparison artifacts used during testing

Build

To compile the project:
