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.
