The purpose of the project is to design a multi-threaded program with use of semaphore and mutex to avoid deadlocks

• POSIX Threads

The project involves use of a processor which sits at the core of a computer. To get to the core, a programming language must be low-level, which means it must provide little or no abstraction of programming concepts and be very close to writing actual machine instructions. My language of choice was C as it is a low-level language and supports multi-threaded programming with POSIX threads library.

To create the program, I first needed to create two groups of threads – worker thread and consumer thread. The worker threads pick a tool from one resource, create a new product with a material randomly generated from other resource and pushes a complete product into anther resource. Then, the consumer threads use a product created by a worker thread. As both types of threads share a common resource such as an array, semaphore and mutex which work as a key to control access to the common resource.
