    Someone posted a very vague query on the C++ forum , and mentioned that he didn't know why his app doesn't work, and he has no clue about the failure modes. There was no relevant information in his post (no code either) that I could have used to guess any possible cause of the problem. I was pissed; I asked him use the debugger. And... his problem is solved. His reply: "Finally I got the clue ... Sometimes u even forget that u always have debugger to help you out. Thanks for help." What?! That's it? Solved?! :rolleyes: I think we should include a new point into the guidelines for asking a question: "Please remember that you have a debugger". :laugh:

      Debugging seems to be a lost art. Somebody should write an article on effective debugging.

          We could include lots of things in the guidelines, but it seems that too many people never read them. They just post their question/demand/incomprehensible message*, and expect an instant solution. *nothing to do with language skills, as many posters with very poor English seem to write a clear enough description of their problem. [rant]Even worse is the "plz hlp" text speak that so many people believe is normal usage.[/rant]

              Depends on the school. We got a few 'projects' which consisted of handing the entire class horrifically failed projects and the instructions 'Fix it'. You learned how to debug fairly quickly, or you failed.

                    I use C# in vs08, F7 is my build key and F5 builds automatically anyway. What was that about platform-dependent algorithms?

                        Switch the ordering. After the initial programing courses every CS or SE student at RIT was required to take Software Engineering 1. Then, Software Engineering 2 (required for SE, optional for CS) was fixing the worst Software Engineering 1 projects you could scrounge up. Given that the first course was one of the major points of attrition in both degrees, you could find some amazing crap in the pile. Just to honor a tradition formed in the later class, and a duck.

                          F9 is toggle breakpoint. Hence F9, F5, Fix.

                            Maybe his code wasn't buggy (e.g., It works but...), but just wasn't producing the correct answer.

                              Trying to make this system idiot proof is like writing a FAQ for your dog that says instead of barking, he should ask nicely "May I bite this cyclist, please?"

                                teaching howto debug and teaching howto use a debugger are completely different things. I graduated in 2002 with a bachelors and never once had an assignment that involved using a debugger. I had tons of assignments where I had to fix non-working programs or simply figure out why something wasn't working but never once did these require the use of an actual debugger. It made me a far better programmer since I don't have to rely on Visual Studio or gdb (or whatever else) to figure out what stupid thing I've told my program to do. Of course, I certainly use debuggers daily to my advantage now, but I was never "taught" how.

                                  My comment of adding another point to the guidelines is a humorous note. I know most of them don't read the guidelines anyways. :)

                                    I was taught in HS quite thoroughly with the turbo pascal debugger. In college I had few pointers with the VC6 debugger from the lab assistant in my CS102 class. For my 1st unix C class the TA advised us that printf > gdb.

                                    3x12=36 2x12=24 1x12=12 0x12=18

                                      My comment of adding another point to the guidelines is a humorous note. I know most of them don't read the guidelines anyways. :)

                                        Maybe his code wasn't buggy (e.g., It works but...), but just wasn't producing the correct answer.

                                        OK, then there's this possibility that he's into Lotus Notes "development" team. :)

                                          teaching howto debug and teaching howto use a debugger are completely different things. I graduated in 2002 with a bachelors and never once had an assignment that involved using a debugger. I had tons of assignments where I had to fix non-working programs or simply figure out why something wasn't working but never once did these require the use of an actual debugger. It made me a far better programmer since I don't have to rely on Visual Studio or gdb (or whatever else) to figure out what stupid thing I've told my program to do. Of course, I certainly use debuggers daily to my advantage now, but I was never "taught" how.

                                          The other day, they very clearly explained a problem to me. A day or two later they asked how it was going, and I explained I was halfway through examining all the source cocde. They thought I was crazy. Oh well...
