A programmer, also known as a coder or software developer, is a professional who writes code to create software programs. These instructions, often written in various programming languages, are essential for computers to perform specific tasks. The instructions, commonly referred to as code, are subsequently tested, debugged, and refined to ensure efficiency and functionality.
