What is Screen Programming?

Screen programming, in its simplest form, refers to programming that directly manipulates the display screen. Historically, this involved directly writing to video memory to control what was displayed. Modern screen programming typically uses higher-level APIs provided by operating systems or graphics libraries (like OpenGL, DirectX, or web-based canvas APIs) to draw shapes, text, images, and manage interactive elements on the screen. It is commonly used in building graphical user interfaces (GUIs) for applications, games, and interactive visualizations.
