Interprocess Communication Using Pipes.

Write a well-comment program which implements interprocess communication between parent and child processes in C++.

Your program should implement the following steps:

1. The parent process creates an unnamed pipe using pipe ( ).

2. The parent process forks (use fork ())

3. The writer (child) closes its read end of the pipe, and the reader (parent) closes its write end of the pipe.

4. The parent and child communicate by using write ( ) and read ( ) calls.

5. Each process closes its active pipe descriptor when its finishes with it.

Note: You may use an example in your LINUX text book (pp501-504 in your LINUX book).

Create TWO unidirectional pipes to implement two-way communication between the parent and a child.
