In this tutorial, we'll walk you through building a simple and functional calculator using React. This project is an excellent starting point for beginners looking to get hands-on experience with React and understand how to manage state and handle events in a React application.
This calculator project allows users to perform basic arithmetic operations like addition, subtraction, multiplication, and division. The calculator has a sleek, user-friendly interface, and it handles all the essential operations, including clearing the input, deleting the last entered value, and calculating the result.
- Basic Arithmetic Operations: Supports addition, subtraction, multiplication, and division.
- Clear (AC) and Delete (DEL) Functionality: Easily clear all inputs or delete the last entered digit.
- Responsive Design: Works well on various screen sizes, with an intuitive button layout.
- Error Handling: Displays an error message if an invalid operation is performed.
- React: For building the user interface.
- CSS: For styling the application and ensuring a responsive design.
The project is structured as follows:
