Lecture 168:- Hint - Calculator

A calculator can be built using HTML, CSS, and JavaScript. The HTML file will contain the structure of the calculator, while the CSS file will be used for styling. The JavaScript file will handle the calculations and display the results on the calculator.

To build the calculator, you can start by creating a basic HTML structure with buttons for the numbers and operators. You can use CSS to style the buttons and make the calculator look visually appealing.

Next, you can use JavaScript to handle the button clicks and perform the necessary calculations. You can create event listeners for each button and define the action that should be taken when the button is clicked.

For example, when a number button is clicked, the number should be added to the input field. When an operator button is clicked, the previous value and the operator should be saved, and the input field should be cleared.

Finally, when the equal button is clicked, the saved values and operator should be used to perform the calculation, and the result should be displayed on the input field.

This is just a general idea of how a calculator can be built using JavaScript. The actual implementation may vary depending on the requirements and functionality of the calculator.
