• Write a program with one thread function, define an array with 5 elements as a global variable [ use the file mutex2.c for this lab].

• Call the thread 2 times
• First for incrementing the array elements by 2.
• Second for incrementing the array elements by 3.
• Give a "sleep(2)" in the for loop of the thread function to model some process happening in between.
• Check if you are getting an expected output of incremented array elements.
