Write a C program (Prog8a.c) that

1. Create 3 child (prog8b) processes such that
   • child 1 reads from pipe 1 and writes to pipe 2
   • child 2 reads from pipe 2 and writes to pipe 3
   • child 3 reads from pipe 3 and writes to pipe 4
2. main then
   • reads string tokens from stdin and writes them to pipe 1 UNTIL EOF on stdin
   • reads string tokens from pipe 4 and writes them to the Display UNTIL EOF on pipe 4

You should use the 'script' command to capture all necessary information for handin.
