###Running the Programs

• Run stp.c ( single-threaded counter ) :

   gcc -pthread 2014021_stp.c 2014021_counter1_nonsafe.c
  

• Run mtp_c1.c ( multi-threaded thread-unsafe counter) :

   gcc -pthread 2014021_mtp_c1.c 2014021_counter1_nonsafe.c
  

• Run mtp_c2.c ( multi-threaded thread-safe counter using mutex_lock):

   gcc -pthread 2014021_mtp_c2.c 2014021_counter2_safe.c
  

• Run mtp_c1_sem.c ( multi-threaded thread-unsafe counter using binary semaphores):

   gcc -pthread 2014021_mtp_c1_sem.c 2014021_counter1_nonsafe.c
