Project Description: CLI-Based Simple Calculator

Overview

The CLI-Based Simple Calculator is a command-line interface application built using TypeScript and Node.js. This project allows users to perform basic arithmetic operations such as addition, subtraction, multiplication, and division directly from their terminal. The calculator is designed to be simple and user-friendly, making it an excellent example of how to create CLI applications with TypeScript and Node.js.

Features

• Arithmetic Operations: Supports addition, subtraction, multiplication, and division.
• User-Friendly Interface: Easy-to-navigate text-based menu for selecting operations.
• Type Safety: Leveraging TypeScript for enhanced type safety and better development experience.
• Modular Design: Clear separation of logic and user interface components.

Implementation Details

• TypeScript: Provides type safety and modern JavaScript features.
• Node.js: Runtime environment for executing JavaScript code outside the browser.
• npm: Package manager used to manage dependencies and scripts.

How It Works

1. User Interaction: The user interacts with the calculator via the terminal, selecting operations from a menu.
2. Input Handling: The program prompts the user to enter two numbers.
3. Perform Calculation: Depending on the user's choice, the calculator performs the selected operation using methods defined in the Calculator class.
4. Output Result: The result of the operation is displayed, and the user can choose to perform another calculation.

Installation and Usage

1. Clone the Repository:

   git clone https://github.com/zainkhan1726/Project00_Simple_Calculator.git

2. Install Dependencies:

   npm i zain-khan-179-simple-calculator

3. Run the Calculator using npx tool:
