A debugger is a computer program used to test and debug other programs. It allows a programmer to execute code instruction by instruction, inspect variable values, and understand the program's flow of execution. Debuggers are essential tools in software development, helping to identify and fix errors, also known as bugs.

When a program encounters an error, a debugger can halt execution at the point of failure. This allows the developer to examine the state of the program at that precise moment. Key features of a debugger typically include the ability to set breakpoints, which are specific lines of code where execution will pause. Once paused, the developer can step through the code, either line by line or by continuing execution until the next breakpoint is hit.

During a debugging session, developers can inspect the values of variables, examine the call stack (which shows the sequence of function calls that led to the current point), and even modify variable values on the fly to test different scenarios. This interactive process is crucial for understanding complex code behavior and pinpointing the root cause of issues.

Debuggers are available for virtually all programming languages and operating systems, often integrated into Integrated Development Environments (IDEs) or available as standalone command-line tools. Mastering the use of a debugger is a fundamental skill for any programmer.
