Philosophers (January 2022, Version 9, 100/100)

I’ve never thought philosophy would be so deadly.
This is my solution for the philosophers project of 42 school.
This is part of common core.

Introduction

This is taken from the subject.pdf.

To run the simulation a few variables are needed:

1. number_of_philosophers: is the number of philosophers and also the number of forks.
2. time_to_die: is in milliseconds, if a philosopher doesn’t start eating ’time_to_die’milliseconds after starting their last meal or the beginning of the simulation,it dies.
3. time_to_eat: is in milliseconds and is the time it takes for a philosopher to eat. During that time they will need to keep the two forks.
4. time_to_sleep: is in milliseconds and is the time the philosopher will spend sleeping.
5. number_of_times_each_philosopher_must_eat: argument is optional, if all philosophers eat at least ’number_of_times_each_philosopher_must_eat’ the simulation will stop. If not specified, the simulation will stop only at the death of a philosopher.

Each action of a philosopher will result in his state beeing printed in the correct order and with a timestamp and his number.
A philosopher can:

• grab a fork
• eat
• sleep
• think
• die

Usage

To compile the programm run make all in the root of the project.
Then run ./philo with the parameters you want to test explained in Introduction as 1. 2. 3. 4. and 5.

i.e.: ./philo 4 410 200 200 4
Now the simulation will start and run until each philosopher has eaten 4 times or dies.

This ./philo 4 410 200 200 should theoretically run infinite.
If you want to see the usage while using you can do ./philo and it will show you the correct usage.
