Introduction

• Thread 2 having function to print 1 to 10 finishes before Thread 1 having function to print 10 to 20
• Thread 1 finishes before Thread 3 having function to print 20 to 30
• Use semaphore(s) to enforce these sychronization rules by adding P() and V() calls
• Finally, you must include sem create calls in suitable places to create and initialize the semaphores.
• Use sem create() calls show the intial semaphore value for each newly created semaphore.
• Do not use any synchronization primitives or techniques other than sempahores.
• code.c is the main file which achieve the goal. without_sem.c is used to illustrate the problem which arises when we don't use semaphores

Requirements

• gcc compiler

Usage

For compilation

• using semaphores

$ gcc code.c -lpthread

• without using semaphores

$ gcc without_sem.c -lpthread

For execution

$ ./a.out
