OPERATING SYSTEMS LABORATORY V - Additional Thread Exercises:

1. Write a program to calculate the factorial of a number. Your program should;
   • create a thread,
   • supply a function for the thread,
   • output the result in the main (function/process/thread).
2. Modify the code given in the fifth example such that;
   • having 5 threads,
   • each thread will increment the value of a global variable by one for 500 times.
   • after each iteration the thread sleeps for a short while (sleep(2)),
   • execute your program several times,
   • compare the output with the fifth example's output.
   • Now, increase the time for sleeping and the value for the loop such as:
     • sleep(12),
     • 5000000,
     • apply the procedure above,
     • what happens!!
