Question:
Processing of commands with `pipes` and `fork`
Write a program that will read a command from a user and execute them. The program should exit
if the user enters a special command called "quit" or "exit". The program should use pipes
to communicate between parent and child processes to implement the desired functionality.
To compile:
gcc Prgm-1.c -o prgm-1-out
To execute:
./prgm-1-out
