42_Philosophers

This project is an implementation of the dining philosophers problem. It enables us to work with concurring thread and processes.
There is 3 declinations of the solution.
Philo_one :

• Each Philosopher is represented with a thread
• Memory access and syscalls are protected with mutexes.

Philo_two :

• Each Philosopher is represented by a thread
• Memory access and syscalls are protected with semaphores
  

Philo_three :

• Each Philosopher is represented by a process
• Memory access and syscalls are protected with semaphores
