Interactive programming, also known as live coding, refers to any computer programming language that allows the creator to make changes to the program while it is already running. In traditional programming, the coder first writes the program and then saves it. It then runs the program on the computer. If an error occurs, it goes back to the drawing board to type the new code and run the program again. With interactive programming, the designer can make changes to the code without having to run the program again.

Another use of interactive programming is to allow user input into what is called an interactive application. This can be as simple as asking the user for their name and displaying it on the screen. The program has an interactive element changing the value of the username based on what the user types. When the program was created, it didn’t know its name and the value was blank. As soon as he knew her name, he put that value into the program while the program was still running and displayed it on the screen.
This type of interactive programming is in contrast to another programming process known as batch processing. In batch processing, the program can be run without requiring user input. This has the advantage of running on its own without needing user help, but it has one major drawback. All the information necessary for the execution of the program must be encoded from the beginning. If the program wanted to display the user’s name, it would already need to know it, as it could not prompt for the user’s input.
When creating a program, it goes through development cycles. These cycles start with identifying what the program is supposed to do, writing the code for it, and testing the program. The designer then goes back and makes changes to the program and tests it again. This process repeats until a successful program is created.
When interactive programming is used, the fine lines between stages in the development cycle become blurred. Writing the program and running it become the same thing. Instead of writing the program and then running it, the developer can write the program, run it, and continue writing or making changes to it as it runs. This allows much more flexibility in programs and allows the programmer or user to make changes without restarting the program.
