POSIX Synchronization

In the Sleeping-Barber problem, a barbershop consists of a waiting room with n chairs and one barber chair. If there are no customers to be served, the barber goes to sleep. If a customer enters the barbershop and the barber is asleep, the customer wakes up the barber. If the barber is busy but chairs are available, then the customer sits in FCFS free chairs. If all chairs are occupied, then the customer is blocked. Using POSIX semaphores, write a program to synchronize the operations of the barber and the customers. Your program should display all barbershop operations. Note: waiting room size n should be initialized by user on the command line.
