The ArrayNet Protocol

A C implementation of a custom packet protocol for array serialization, deserialization, and integrity checking. This project demonstrates low-level data manipulation, bitwise operations, and robust testing practices.

Features

• Packet Serialization: Convert integer arrays into network packets with custom headers and payloads.
• Packet Deserialization: Reconstruct arrays from received packets, handling fragmentation and corruption.
• Checksum Calculation: Ensure data integrity with a custom checksum algorithm.
• Packet Inspection: Print detailed packet contents for debugging and analysis.

Building

This project uses CMake:

cmake -S . -B build
cmake --build build

• The main executable: hw1_main
• All tests: run_all_tests
• Standalone Valgrind test drivers for memory checking

Testing

Unit and integration tests are written using GoogleTest. Run all tests with:

./build/run_all_tests

Valgrind test drivers are also available for memory analysis.

Example Usage

The main program (hw1_main.c) demonstrates how to print a packet’s contents.
