C PROGRAM:

Create a C program that creates as many processes as there are files on the command line (if no files on command line, only 1 child process should be created).

Each process should count words, lines and characters according to the specified options of one file only and write the result to a pipe.

The parent process should read from the pipe and display the grand total. The program should also display the process-id of the counting process next to the file name
