 ### Reader-Writer Problem with Synchronization
 - Write a C program that involves multiple processes/threads where one of the processes/threads is a writer while there are multiple reader processes. 
 - You need to take care of problems related to race conditions using POSIX mutexes and semaphores. The processes may use a shared memory for 8 bytes (64-bits) that could be written to or read from.

 ### Dining philosopher problem
 - Write a C program to solve the dining philosopher problem where the philosophers are represented by threads. You need to ensure that your solution is free of deadlocks, i.e. it should be designed such that it avoids/prevents deadlocks.
