You must NOT use the C library function "system'' Write a shell program in C similar to "csh" that takes commands from thekeyboard. In particular, your shell prompt must be the current time(instead of, say, % as is common in UNIX).Make it simple; that is, do not allow it to handle background processes, it can ignore the control-C key, and especially, do not design it tointerpret shell scripts.

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.
