C Assembler Project

A complete two-pass assembler for a custom assembly language, developed as a final project for the Systems Programming Laboratory course at The Open University.

Key Features

• Two-Pass Algorithm: Implements the classic two-pass mechanism to first build a symbol table and then translate the code.
• Macro Support: Includes a pre-assembler stage that handles macro expansion.
• Error Handling: Detects and reports a wide range of syntactical errors in the source assembly files.
• Multiple Output Files: Generates object, entry, and external files, demonstrating an understanding of the linking process.

Technologies Used

• Language: C (C99)
• Build System: Makefile
• Core Concepts: Dynamic Data Structures (Linked Lists), Manual Memory Management, File I/O.

Getting Started

To compile and run the assembler:

1. Clone the repository:

   git clone [https://github.com/Talnet054/Systems-Programming-Project.git](https://github.com/Talnet054/Systems-Programming-Project.git)

2. Navigate to the project directory:

   cd Systems-Programming-Project

3. Compile the project using the Makefile:

   make

4. Run the assembler with an assembly file:

   ./assembler <your_assembly_file_name>
