1.Description: This is a Command Line Interface (CLI) based simple calculator that performs basic arithmetic operations, when run in a terminal or command prompt environment. It provides users with a straightforward way to perform simple arithmetic operations of addition, subtraction, multiplication and division using text-based input and output.

2.Features:

Arithmetic Operations:

Supports standard arithmetic operations such as addition (+), subtraction (-), multiplication (*), and division (/).

User-Friendly Interface:

Utilizes a text-based interface for user interaction, displaying prompts and results directly in the command line.

Error Handling:

Implements error handling to gracefully manage scenarios such as invalid input, providing clear error messages to the user.

3. Purpose: The CLI Simple Calculator serves as a lightweight and versatile tool for performing basic mathematical calculations quickly and efficiently within a command line interface.

4. Implementation: Implemented using a programming language and some packages such as typescript,node.js,inquirer and chalk. The CLI Simple Calculator leverages basic input/output operations to interact with users via the command line by using inquirer and usage of chalk make the calculator more attractive. It employs fundamental arithmetic algorithms to perform calculations and incorporates error handling mechanisms to ensure reliability and user satisfaction.
