Phase $1$: Initial Setup with Inter$-$process Communication

To get started, you$$ll focus on creating two processes that can communicate through a pipe. One process will take user input and send characters to the other process, which will receive and display them. The goal is to familiarize you with creating basic inter$-$process communication $($IPC$)$ before diving into more complex OS functionalities.

Commands:

The program should display a prompt $($e$.$g$.,$$$)$ and accept user input. You$$ll implement four commands:

Q: Signals that a time unit has passed.U: Unblocks a process in the blocked queue.P: Prints the current state of the system.T: Ends the simulation and shows the average turnaround time for processes.

Handling Commands:

For this phase, simply send each command character $($Q$,$U$,$P$,$ or$$T$)$ to the pipe.The receiving process will display the received character and wait for the next input.Terminate the program when the user enters$$T$.$
