What’s self-modifying code?

Self-modifying code is a programming philosophy where the program can alter its coding when it runs. It improves itself without interaction and deletes unnecessary code. It is not the same as unintentional encoding changes and can improve processing and reduce path length.

Self-modifying code is a programming philosophy in which the developer creates a program that can alter its coding when it runs. While the developer can enter parameters for self-modifying code, it usually changes and optimizes itself without interaction. There are some computer phenomena that cause encoding to change unintentionally, but only intentionally self-modifying code is truly considered self-modifying. This is most commonly used by developers to improve their coding, because running the coding many times can greatly improve the original design.

The most defining aspect of self-modifying code is its ability to change itself for the better. This can only be done when the code is ready to run and when it is preparing to run. Running code will need to take stock of the computer’s current software, status, and other factors, so this usually helps the code recognize processing errors to best correct its own processing.

Developers sometimes set parameters for self-modifying code, such as fixing itself mostly for performance, but the code will normally fix itself without interaction or prompting. In addition to the increase in processing, the code will also delete unnecessary code that is just dragging the program down and reduce the path length. At the same time, developers can specify areas that cannot be changed, since altering some parts of the code may cause the entire program to malfunction or stop working.

Occasionally there is a phenomenon in software where the encoding changes without the developer writing any instructions to do so. This usually occurs with broken software or buffer problems, and while the encoding is changed, it is not considered self-modifying code. There are two reasons for this, one is that the change was not intentionally done by the developer. The second reason is that self-modifying programming is meant to improve encoding, while buffering and rot problems degrade encoding.

There are many advantages to having self-modifying code, because it will constantly work to improve itself based on the current state of the computer and other internal factors. This is more strictly used by the developer before the code is sold or distributed. By allowing the code to run constantly, it allows the programming to correct itself and any errors or problems caused by the developer while creating the code. Another use for this is in computers with limited memory, because this code will respond to a memory shortage by shrinking its own size.
