I saw some other entries on this but they dont include case or switch [/QUOTE] well, here it is, if my number spelling is not quite correct...srry a switch is still used, but it's much smaller … |
| | ok, I've checked the forum and I don't think this topic was touched. What I would need is an open-source or at least free static analysis tool for C++ code. Does anybody have any suggestions? I mean, searching the web C++ lacks A LOT at this chapter, compared to Java, … |
| | if u pass a std::vector by value to a function, does all of it's content get copyed? thx |
| | i don't know what "convolute a gaussian" actually is... probably because I skiped my math class :) ... but, in cases like this you should do a study over the algorithm ivolved ( you could even post some links here so we can see it too ) and then try … |

| | ok, so visual C++ is not C99 compliant, but I was wondering how can I access fixed bit length integer types as the one defined in stdint.h (intN_t). thx in advance  |
| | [QUOTE=ArkM;734101]Obviously the possible solution depends on the general architecture of your application (and run-time environment). In standard C++ an object life time defined with regard to the only execution thread and it's not a real time.[/QUOTE] Hmm, i find this question very interesting, and as ArkM said, it's very run-time … |

| | ok, u solved your problem, but still there are some problems you should notice: 1. never put function definitions inside a header file, just the declarations. If you want to include that header in more compile units you will end up with a linker error because the compiler will generate … |

| | Well, C++ is just a language, with quite a small standard library, but with A LOT of provided compilers, frameworks and third party libraries. From my point of view ( and many others, I think ) g++ is the best compiler for C++. Visual C++ is quite a generic name: … |

| | hmm, the thread name is kind of missguiding this should better be "error linking to loki" as you can see all your .o files compile fine, but the linking is the problem did you build the Loki library? I know Loki is mostly a template library that need not be … |

| | Anyway, this is OS dependent, but I really can't find any other way except the looping. Another way would be to check all the interrupts at kernel level and see what system calls refer to your folder and would modify it's content, but I don't think this is legal or … |
| | hmmm, ok, sorry, but your ideea with the file being the chatroom or whatever just isn't good !! First of all, you have to synchronize all acces to that file. When one user is writing the file all others must wait. When one user wants to print the "chatroom" he … |

| | Re: pointer of course the pointers in the structs point to the same thing. That is because you do a shallow copy. If you want the two char pointers inside the structs point to diffrent strings you need to do a deep copy ( copy the content pointed by the pointer in … |
