Detailed Description

A simple command-line program that processes user input.

This program provides a command-line interface where the user can input commands. It uses a CommandParser object to process each line of input. The program is designed to handle SIGINT (Ctrl + C) gracefully and provides an interactive prompt for the user to enter commands.

When the user presses Ctrl + C (SIGINT), the program will display a message reminding the user to exit using the "exit" command or Ctrl + D. The program clears the screen on startup and repeatedly prompts for user input until the program is terminated.

Note: The command-line input is passed to a CommandParser class for parsing and processing.
