Philosophers🍝🍴

Description Philosophers

This projects involves making use of threads and mutexes. By precisely timing a group of philosphers on when to pick a fork and spaghetti without dying from hunger.

To succeed this assignement:

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.

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

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!

Installation ⚙️

*To build the programm there is only a few steps: First of all, you can download the repository through the following steps in any shell of your preference:*

[email protected]:AtibQur/philosophers.git
cd philosophers
make

These commands will compile everything and a executable "philo" should be created.

Usage 🛠️

To compile the program, run the following command:

cd philosophers && make

After creating the executable, the function is ready for use. This function only takes integers and will return errors if a non numeric character is used.
The program takes 4 or 5 arguments:
1: ./philo
2: amount of philosopher
3: time to eat
4: time to sleep
5: amount of meals to eat (optional)

./philo 3 410 200 200 5 --> will fail

./philo 4 410 200 200 5 --> will run till amount of times to eat is true
