This program demonstrates how IPC can be used to communicate data between two processes.

The program will do the following when it runs:

1. The user is asked to enter the number of bytes of data that should be transferred. This

value is passed to the generate_data function to create a data string of that many bytes

to be transferred between the parent and child processes.

2. A function named pipe_xfer is called to create a child process and use a named pipe to

transfer the data string from the parent process to the child. After the transfer is

complete, the child process will verify that it received the data correctly and display the

result to the terminal.

3. After pipe_xfer is finished, a function named msg_xfer is called to create a child process

and use message queues to transfer the data string from the parent process to the child.

After the transfer is complete, the child process will verify that it received the data

correctly and display the result to the terminal.
