    Question Stupid question: What does Debugger do?

    Post Debuggers

    No need to feel stupid. You could only learn by asking questions.

    A debugger, generally, is a program that interrupts the processor while reading instructions and allows the user to view, step by step, each instruction before it runs. The debugger provided with C++, visual studio, or whatever it comes with will allow you to look at the instruction in the program that had an error. So any program in windows that has an error you can debug. There are many errors, so you will get a chance to see this... trust me. So it's basically almost comparable to the debugger in VB, you can go step by step in the code to see what is wrong, or if there was anything wrong.

    Hope this helps

    i'd add that a debugger allows you to change your variables to anything you want, which helps if you have an unlikly if statment that you want to test.

    Man I want to learn how to use a debugger but I haven't been able to learn how to dont' know where to start, anybody have any suggestions? I have MSVC++.. as well as some Borland debuggers for win32 DOS or some other stuff, I mean that's what it says, and I have yet to get any of them working.
    There are some real morons in this world please do not become one of them, do not become a victim of moronitis. PROGRAMMING IS THE FUTURE...THE FUTURE IS NOW!!!!!!!!!

    It debugs.

    Ever have a program crash on you? Thats a good time to learn how to use the debugger... step through the program and view your variables, you'll probably find where the logic error occoured. I was once looking for a tutorial on it, probably a few months ago... but since then I've made a few logic errors which have crashed my program, and with testing out the debugger, I found them. It's not as complicated as it looks.

    On a side note, I'd marry a debugger if I could.
