Q.No.1.

Write a single program to perform the following tasks:

1. Main process should create a child process. Both parent and child processes will create one thread (e.g. parent process thread A, child process thread B).
2. Compare the ids of parent and child, parent process and thread A, parent process and thread B, child process and thread A, child process and thread B. Display appropriate messages as per your comparison results.
3. Parent process will take a number from user as input and will pass on this number to thread A while creating it. Before doing anything else, thread A will print the cube of that number.
4. Parent process will perform some tasks and then wait for the termination of child process. Similarly, thread B will wait for the termination of thread A before starting execution. Each process and thread will display an appropriate message before its termination.
5. Parent process will send your Name and Registration number to the child process and you will save them in two different variables. You have to use pipes for this purpose. Later on, thread B will display these values as an output.
6. Make sure to display appropriate messages and terminate normally using exit if there is any problem in child process/thread or pipe creation.
