# Philosophers

One or more philosophers sit at a round table. There is a large bowl of spaghetti in the middle of the table.

The goal of this project is to learn how to use threads and mutexs, also in bonus part i recode the project using multiprocess and semaphore.

Overview:

• One or more philosophers sit at a round table.

  There is a large bowl of spaghetti in the middle of the table.

  

• The philosophers alternatively eat, think, or sleep.

  While they are eating, they are not thinking nor sleeping;

  while thinking, they are not eating nor sleeping;

  and, of course, while sleeping, they are not eating nor thinking.

  

• There are also forks on the table. There are as many forks as philosophers.

 

• Because serving and eating spaghetti with only one fork is very inconvenient, a

  philosopher takes their right and their left forks to eat, one in each hand.

  

• When a philosopher has finished eating, they put their forks back on the table and

  start sleeping. Once awake, they start thinking again. The simulation stops when

  a philosopher dies of starvation.

  

• Every philosopher needs to eat and should never starve.

• Philosophers don’t speak with each other.

• Philosophers don’t know if another philosopher is about to die.

• No need to say that philosophers should avoid dying.
