Virtualized Operating System Project

Overview

This project is designed to implement multiple C scripts within a virtualized operating system environment. The tasks focus on input/output operations, process management, client-server communication, and multi-threading with synchronization.

Project Tasks

Task 1: Standard Input/Output Script

1. Create a script using C that:
   • Reads any data from the standard input device.
   • Writes the data to the screen.
   • Handles data of any length.

Task 2: Date and Time Script

2. Create a script using C that:
   • Prints the day of the week.
   • Creates a forked process to print the current date.

Task 3: Client-Server Communication

3. Create three C scripts:
   • Script A (Server)
     • Prints the messages received from Scripts B & C.
     • Replies to the messages received from Script B or C.
   • Script B (Client)
     • Sends the message "This is Client B" to the server.
     • Prints the reply received from Script A.
   • Script C (Client)
     • Sends the message "I am Client C" to the server.
     • Prints the reply received from Script A.

Task 4: Multi-Threading with Synchronization

4. Create a script using C that:
   • Creates two threads (Thread A and Thread B).
   • Ensures the threads alternate using a Mutex lock to achieve synchronized output.
   • The output sequence should follow:

     1 ➔ 2 ➔ 2 ➔ 4 ➔ 3 ➔ 6 ➔ 4 ➔ 8 ➔ 5 ➔ 10 ➔ 6 ➔ 12 ➔ 7 ➔ 14
     

     • Thread A prints numbers from 1 to 7.
     • Thread B prints even numbers from 2 to 14.
