How does the program ensure philosophers eventually stop?

By using a max eat counter
When the system runs out of resources
With an interrupt from the user
Using a scheduled executor shutdown

The correct answer is: With an interrupt from the user

The program ensures philosophers eventually stop by utilizing an interrupt from the user. This means that the user can terminate the program at any time, causing the philosophers to stop. Option A, using a max eat counter, may not be effective as it may not accurately represent when the philosophers are finished eating. Option B, when the system runs out of resources, may not be practical as it could potentially cause the program to crash or malfunction. Option D, using a scheduled executor shutdown, may not be reliable as it relies on the program to end at a predetermined time, which may not always match with when the philosophers have finished eating. Using an interrupt from the user allows for more control and accuracy in determining when the philosophers will stop.
