Simple Calculator

A basic web-based calculator built with HTML, CSS, and JavaScript. This project allows users to perform fundamental arithmetic operations such as addition, subtraction, multiplication, division, and modulus through a simple and intuitive interface.

Features

• Supports basic arithmetic operations: addition (+), subtraction (-), multiplication (*), division (/), and modulus (%).
• Clear button (C) to reset the display.
• Responsive design for use on various screen sizes.
• User-friendly interface with a dark theme and hover effects on buttons. -Error handling for invalid inputs (e.g., division by zero).

Technologies Used

• HTML: Structures the calculator's user interface.
• CSS: Styles the layout, display, and buttons for a clean and modern look.
• JavaScript: Implements the calculator's logic, including button interactions and expression evaluation.

Getting Started

Prerequisites

• A modern web browser (e.g., Chrome, Firefox, Edge).
• No additional software or dependencies are required.

Installation

Clone the repository:

git clone https://github.com/kesavanaswin/Simple-Calculator.git

Navigate to the project directory:

cd Simple-Calculator

Open index.html in a web browser to use the calculator.

Usage

• Click the number buttons (0-9) to input digits.
• Use the operator buttons (+, -, *, /, %) to build expressions.
• Press the equals button (=) to evaluate the expression.
• Use the clear button (C) to reset the display.

Project Structure

• index.html: Contains the HTML structure for the calculator's interface.
• style.css: Defines the styling for the calculator, including layout and button design.
• script.js: Handles the logic for button clicks, expression evaluation, and error handling.

Limitations

• Uses JavaScript's eval() function for expression evaluation, which is suitable for this simple application but not recommended for handling untrusted inputs in production environments.
• Limited to basic arithmetic operations; no support for advanced functions like square roots or memory storage.
