In this project, you will learn the basics of threading a process. You will learn how to make threads. You will discover the mutex.
42's take on the classic Dining philosophers problem. The mandatory part was done using the phtread API to execute n numbers of threads at once that eat, sleep, then start eating again. Mutex was used to manage the limited resources available. Given the right parameters, philosophers keep repeating their cycle virtually forever, unless a maximum number of times each philosopher must eat before the simulation ends is given. Examples:
n_philosophers time_before_death time_eat time_sleep [time_eats]
4 410 200 200
5 800 200 200 5
