GDB (GNU Debugger)

GDB, or GNU Debugger, is a tool used by programmers to test and debug their software. When developers write code, it's common for errors, or "bugs," to occur. GDB helps identify where these bugs are by allowing programmers to run their code step by step, inspect variables, and examine the program's behavior in real time. This process helps them understand how the code operates and fix issues more efficiently. Essentially, GDB serves as a guide, helping developers ensure their software runs smoothly and correctly.
