What is Debugger?
It is a debugging tool that allows finding and fixing bugs in software by tracking them step by step.
Overview
It is a special utility program that allows you to infiltrate the code during the software development process and see live how each line works. The code written by programmers does not always work correctly the first time and can lead to unexpected crashes or incorrect results. A debugger allows you to stop the execution of the code at the point you want, inspect the values of the variables at that moment, and pinpoint the source of the error.
How it works
You place a breakpoint on a specific line of your code. When you run the program, it stops right at that line, and you can watch live, step by step, which variable breaks and when.
Where it is used
It is frequently used in software development environments, web browser developer tools, and background error analysis of complex systems.
Commonly confused with
It can be confused with a compiler. While a compiler translates the entire code into machine language, a debugger focuses on finding logical errors within the running code.
Questions and answers
Can I not debug without a debugger?
You can also search for errors by continuously adding print commands to the screen between the code, but this method is very slow in large projects and does not provide as in-depth information as a debugger.
What is a breakpoint?
It is a marker you place on the line where you want the code to pause while running; when the debugger reaches this point, it freezes the program.
