After playing our giving implementation, your task is to implement Dinning Philosophers
with semaphore in C, by including and
Your implementation will require creating five philosophers, each identified by a number
0.4. Each philosopher will run as a separate thread. Create threads using Pthreads
as discussed in the Lecture slides on Chapter 4 and Practice Lab on Threads.
Your solution needs to accomplish the following:
Implement in C (15 points)
1. dp1.c - You are to provide your solution to this assignment as a single C program
named 'dp1.c using semaphore. Explain in you code (as comments) that the dead
lock will happen or not. If there is a possible deadlock, you can simply solve the
deadlock by pick the fork in order like the first solution in our slides.
Solve Deadlock by Footman (15 points)
1. Here is a new solution to overcome the deadlock. The Dining Philosophers decide to
hire a footman whose task to allow only four philosophers to sit on the table. When
entering and…
