 | Re: Question They use massive amounts of C, assembly, and often C++. Nothing fancy like .NET. ;) If you're thinking about creating one... nah. Or at least spend a few years learning C before attempting it, and bring a whole crew of programmers with you when you do start. |
 | [quote=degamer106;314890]This might seem like a silly question, but how do I read in a newline char, by itself, as input? For example, if I gave the user a choice to enter a string for a new filename, or let them just press ENTER for some other choice. forgot to add …  |
| | I believe that you have to free each individual member of an object first (assuming of course, that the object contains data members that were dynamically allocated), [I]before[/I] you can delete the actual object itself. That's what the object's destructor is for; so use it wisely. If the actual object …  |
| | I'm not entirely sure what the problem is, but something doesn't good in your code when you're mixing the getline() statements and in >> operators... You see, when you use [inlinecode]istream >> a_variable[/inlinecode], it always leaves a trailing newline in the input stream. Then when you try to use getline(), …  |
 | [quote=Sturm;314846]I checked the hp website supposdly I have a SATA hardrive not an ATA one. But whatever...[/quote] That's your problem. Many older Linux distributions (i.e. v2.4 kernels) still don't have kernel support for the newer SATA hard drives, and thus cannot recognize it. I had similar problems trying to run … |
| | Upgrading will cost too much for what you want to do with your computer. Even the cheap-ish computer is kinda low on RAM, so it's not going to be quite ideal for your needs either. You'll want [I]at least[/I] 512 MB - 1 GB to be ideal. The Sempron 2800+ … |
| | [quote=beastpopo;314852]Hi, I recently bought a used powerbook. It works but the only thing is it has the system under what I assume is the original users name so I cannot tweak the email or go into the system to change anything. My question is this, can I reset the whole … |
 | Something tells me you're missing a = here: [code] if(reEnter [COLOR=Red]=[/COLOR] true) { binToDec(); }[/code] Also, when you know that the number isn't true, you break out of the loop before the statement I just showed gets executed. Which brings up another point: why are you using recursion for a … |
| | Re: adding library Usually, you need a static library (.lib) for any DLLs you use in your program. Anyways, I don't know Borland, but here are the general steps for setting up a compiler to use an external library:[LIST=1] [*]Get a hold of the necessary files to use the library. [*]Configure the compiler's … |

| | Hmm.. I'm slighty confused, but perhaps you're thinking of a static member? It would sorta work like this: [code] class CShip { public: // .... static int maxCargo; }; [/code] Then for each class you can set this variable, and it will remain the same throughout all instances of the … |
| | Hmm... perhaps you want to overload the behaviour of [inlinecode]<<[/inlinecode]? I'd say create a base class [inlinecode][B]CFileWrite[/B][/inlinecode] which implements member functions which print to a file and to the screen. Then perhaps for each sensor object you overload the << operator to your needs. [code] class CFileWrite { protected: void … |

| | Re: C++ const help [quote=blackjack;314344]Basically, I need to step through any array using pointers instead of the array indices. I changed my char* ptr to const char* ptr and it does work. Thanks.[/quote] But why would having a second [inlinecode]const char*[/inlinecode] copy do you any good? Neither pointer can you modify, so copying it … |
| | NTFS and Fat32 are just different types of partitions. Your main hard drive is using the more modern filesystem NTFS, while the hard drive you just installed uses the older type Fat32. It doesn't really matter much, although NTFS is supposedly faster and safer than FAT. If you care, you … |
 | It's a joke. No normal person would do something that dumb for real. |
| | [quote=Matt Tacular;314040]How do I do that? I'm very new to c++.[/quote] I would assume it would be something like: [code]char x[] = "10110101"; if (x[4] == /* whatever here */) { } // convert number to to decimal here // ... [/code] |

| | Re: Global Dimming I just about killed myself laughing at the irony of this "dimming". Typicial - the scientists have already identified the problem, the cause, and the solution, plus they say that we've already solved it. What really ticks me off is when they blame us North Americans (meaning U.S.) for all … |
| | Re: file problem Depends what you want to do with them. Since they're seperated by spaces, you could simply read them directly from the stream into the variable like this: [code] float floatAmount; while (absoluteval >> floatAmount) { cout << floatAmount << endl; }[/code] Of course, if you actually want to store the … |
| | Re: Puzzle game C or C++? This type of game would be suited to C++, in my opinion. I would create a base class, CObject, which would represent an object in the game. It could contain variables such as position, veloctiy, state and dimensions (size). Then for a book, I would derive a … |

| | I don't know enough about your Mac to really know, but from the sounds of it you have more than 1 partition on your hard drive. You're probably booting from one, and that's the one that is full. One way to tell for sure is to open up System Preferences, … |

 | [quote=WaltP;313279]$35 a year down the drain....[/quote] $35? Nowadays you can get domains for $10 or less... I agree though that it's a stupid way to use the domain, especially when it's such a common word (I found that site just by accident a while back). |

 | [quote]i<(num/2)+1[/quote] This line only loops until half of the number. That's because when you're determining factors for a number, anything larger than the number divided by 2 obvioulsy can't go evenly into the number. So to save time it cuts the number of loops it has to do in half. … |
| | I believe some Xorg configuration is needed. I found this Gentoo wiki page on configuring mice so all the buttons work properly: [url]http://gentoo-wiki.com/HOWTO_Advanced_Mouse[/url] A bit complex, but hopefully not too difficult to follow. Let me know if you get stuck. |
| | That computer is too old for Fedora Core 6. You might as well just forget it. Consider something that takes less RAM such as Xubuntu or Debian - Xubuntu being the distro which will recognize your hardware better, which seems to be an issue for you. |

 | Re: a C++ gui >What toolkit would you recommend with Visual Studio 2005? .NET if speed and portability isn't an issue, and you want to create interfaces using drag-and-drop technology. A good portable toolkit is [URL="http://www.wxwidgets.org/"]wxWidgets[/URL], which allows you to create interfaces using the platform's native interface code. It actually looks quite good. |
| | Re: Beginner >hello there, im new here and i want to start learning c++. You'd be better off learning and being comfortable with C/C++ before you start learning Windows GUI programming.

| | Your input and output methods are weird - consider something like this: [code] char line[255]; while(1) { fgets(line, 255, stdin); // NOTE: ideally you should validate input before printing to file fputs(line, fout); } [/code] Anyway, you can't just use [inlinecode]stdin[/inlinecode] in place of a char *, which is what … |
 | Depends what you want to do with C/C++. If you're really serious, buy yourself a good book as described in the sticky thread previously mentioned. However, you can learn a significant amount from online tutorials, and although they only get you to a certain point, that point is actually far … |
 | Agreed with [B]Sanjay[/B], comments should only be added when they are needed. Why? You're not trying to teach someone the C/C++ language -- and although you may have a difficult time initally understanding the code, someone who is experienced with C/C++ will just have a harder time distinguishing between "junk" … |

| | What exactly is this line for? [code] if ( choice1 = choice1 )[/code] Basically it's doing nothing. For one, it looks like you were trying to check a value, except that you need a ==. And for another, you aren't even comparing the variable with anything. Perhaps you want to … |
