Debugging is the act of finding and fixing current and potential errors (often known as “bugs”) in software code that might cause it to behave abnormally or crash. It is used to detect and fix bugs or problems in software or systems to prevent them from malfunctioning. Debugging becomes more difficult when several subsystems or modules are tightly connected, as each modification in one module may cause more bugs to arise in another. Debugging a program can take longer than programming it.
