Debugger
A debugger is a software tool used by developers to test and debug other programs by allowing them to pause execution, inspect variables, step through code, and identify errors. It provides features like breakpoints, watchpoints, and call stack analysis to help isolate and fix bugs in code. Debuggers are essential for understanding program flow and diagnosing issues during development.
Developers should learn and use debuggers when writing, testing, or maintaining software to efficiently locate and resolve bugs, especially in complex or large codebases where manual debugging is impractical. They are crucial for debugging runtime errors, memory leaks, and logic flaws in applications, such as web apps, mobile apps, or system software, improving code quality and reducing development time.
