To C/C++ programmers that want to ask real world technical question on Stack Overflow:

If possible, do not ask here, most of the time it's a waste of time. It'd be much more effective to go to a dedicated forum. But if you still decide to try, remember to tag your question only with specific technology tag so that it will only attract genuine domain expert.

DO NOT tag your question with C++ or C. Those language tags have serious user base problem, they have already become a useless trivia showcase and homework solving center. You don't want to expose your question to unwanted audience, otherwise some i++++ parsing "experts" incapable of solving a bit of your actual problem will happily nitpick unrelated stuff in your question to show off their "knowledge".
