Reader-Writer Problem Solution using Semaphores, Mutex, and Pthreads

This repository contains a solution to the classical Reader-Writer problem implemented in C language, utilizing semaphores, mutex, and pthreads.

The Reader-Writer problem involves multiple threads that consist of:

• Readers: Concurrently read a shared resource.
• Writers: Concurrently write to the shared resource.

The constraints are as follows:

• Multiple readers can access the resource simultaneously.
• Only one writer can modify the resource, and no other thread (reader or writer) can access it while writing is in progress.

• rw_s.c : This file contains solution of classical reader-writer problem using semaphore & pthreads.
• rw_m.c : This file contains solution of classical reader-writer problem using mutex & pthreads.

• Semaphores: Used to control access to the shared resource.
• Mutex (Mutual Exclusion Lock): Ensures exclusive access to the resource for writers.
• Pthreads: POSIX threads library utilized to create and manage threads.

1. Clone the repository:

   git clone https://github.com/your-username/reader-writer-solution.git

2. Compile the code:

   Compile the code in linux environment (one like WSL) if you don't have one use online compiler.
