(1) Create a C server program and a C client program. The client program reads a line from a text file, converts everything to upper case letters, and send it to the server, using a named pipe. It pauses for 1 second, and repeats the above process, until the end of a file.

The client sends a "Stop" string at the end.

The server displays any thing it receives. The server quits when it sees "Stop". The server needs to cleanup by deleting the named pipe.

The programs (client and server) need to create the name pipe first, if it does not exist.

(2) Re-implement Part 1, using SysV shared memory.

(3) Re-implement Part 2, using mmap() to create a shared memory area between the client and the server.
