Philosophers is a project about solving the dining philosophers problem by writing a simulation of philosophers sitting around a table. The philosophers alternatively eat, think, or sleep. Once a philosophers is done eating he will sleep, afterwards think and then eat again. There is a fork for every philosopher and 2 forks are needed for a philosopher to eat. Once a philosopher starts eating his time to die will be reset and the other philosophers can't access the forks anymore while he eats. If a philosopher dies the simulation will stop.
This project is about writing effective code, learning about threads, mutexes and all the problems that may come along with it, like data races.

- git clone or fork the repository
- run
maketo create the executeable - run it with
./philoand the needed arguments (amount of philos, time to die, time to eat, time to sleep, *number of meals)
*number of meals is not necessary for the simulation to work
- I really recommend watching the threads videos by CodeVault to get started with threads
- Even though I didn't use one, I recommend using a *"reaper thread" because it makes your simulation way faster
- Mutex lock everytime you access a shared variable to avoid data races, bools don't need to be locked necessarily because they only have 2 values
*a reaper thread is a thread running along with the philosophers checking if one of them died and if so exiting the program
