Debugging is the process of identifying and fixing errors (called bugs), or other issues in software code. It involves troubleshooting and resolving problems in order to correct the intended behavior of the software.
A debugger is a tool used by developers to identify and fix bugs in software code. It allows developers to step through code, inspect variables, and track the flow of execution to understand how the code is behaving during runtime. Debuggers are commonly used in integrated development environments (IDEs) to aid in the process of debugging.
