Write a simple shell program in C. The shell program executes a loop to accept commands from the user and executes the command in a child process. This is a very basic version of a shell command program. You can assume that the executables for the commands that the user may enter do exist in the (/bin/) directory. The shell program is very basic, it does not support command line arguments nor advanced features such as piping.

Object Oriented Programming System (OOPs) is a programming model built on the perception of “objects” that contains data and methods. The major purpose of Object Oriented Programming is to increase the maintainability and flexibility of programs. Object Oriented Programming gets together data and its behavior (methods) in a single location (object) which makes it easier to understand.
