Please write code yourself.

Write a multithreaded C program and some multithreaded tasks. The program should do the following: One thread gets a reference string from the user. Then, a second thread will implement FIFO page replacement algorithm in a way that users can enter a number of frames, and simulate algorithm then calculate the number of page faults. And lastly a third thread should print the page faults. In order to get full grade, you should explain your code using comments. Hint 1 : For further and more detailed information about Pthreads, you can examine section 4.4.1 from your course book (9th edition). Hint 2: Sample programs for the implementation of Phreads is provided in Figure 4.9 from your course book (9th edition)
