 | You didn't link with the DirectX 9 .lib files, did you? You have to setup your compiler to properly find and link the libraries. Generally you need to enter in libs such as d3dx9.lib, d3dinput9.lib, etc. into the "libraries to link with" text box in your "project settings". A good … |

| | Actually the OP more-or-less did this. The algorithm does not work. Let's take what the program's output is supposed to do in this example: [code] User enters $4.63. Your output should be: The least number of coins required to make up $4.64 is 4. The coins needed are: 1 Twonie … |

| | Re: C++ Graphics!! Depends what you are trying to do with graphics. There isn't a standard way to do console graphics, although you can use the WinAPI to accomplish it if you choose. Here's a sinppet that accomplishes this: [url]http://www.daniweb.com/code/snippet173.html[/url] The other way of doing graphics is through a Windows GUI application, which … |
| | Re: ifstream help >airportSource.open(airportFileName); ifstream::open() expects a C-style string as a parameter, not a C++ string.

| | A big THANK YOU for using code tags! You are one of the few newbies that actually read the rules and follow them from the first post. 2 things that caught my eye right away: Never include cpp files. Since they are implementation files, all that should be required is … |

If the terminal cannot find the command, perhaps you had better check to make sure it's there. Type the following at the prompt: [code] # …  |
| | Agreed, Gnome is generally more appealing to Mac users than other window managers. If you really like Mac OS X, consider installing this theme after Gnome and Beryl are installed: [URL]http://gnome-look.org/content/show.php?content=50977[/URL] Enjoy ;) |
| | >lol i drink like 12 cups of tea per day That's actually pretty scary. I can't stand either of the substances myself -- coffee is far too bitter, and tea just tastes like hot water. :D |
 | Funny it even compiled. How in the world is the compiler supposed to know which statement is the evaluation statement, and which are assignment statements? Try changing the loop (eg. while() loop), and then it will work properly. By the way, placing an else() statement after the if() and then … |

| | Several problems in your code. 1. `gets` has no bounds-checking when it gets input, instead you should use `fgets` . 2. This code: `strcpy(word[nwords], tword);` This is copying an entire string into 1 character of the string. Use 2d array of chars if you want to have an array of … |

| | Re: Won't read .h >I am using Devx. Compiler do you have any idea how i should link the files together? There's an "add source file to project" button or something similar to that (been quite a while since I used Dev). Once the CPP files are added, everything should work as expected. |

| | Regarding the compiler: why are you still using CodeWarrior? Apple's Xcode application is a free download, is of commercial quality, and provides roughly the same functionality (and more) of CodeWarrior. Also, I believe that using Xcode's Build & Run button actually invokes the application from the command line, eliminating the … |

Because otherwise it (compiler I guess) would have no way of knowing which object you're … |
 | Yes, this is normal C++ class/object behaviour. Part of this, in my opinion, may be due to the fact that in linked lists you often need to modify the object in the next node, or the one after that. This way, you can modify the values without having to traverse … |
| | Re: C++ / Exceptions Your second example is even worse because the object will go out of scope as soon as [INLINECODE]do_that_thing()[/INLINECODE] returns, so any usage of it [U]inside[/U] the try ... catch block will now be illegal. Back on topic: If you really need to use code outside the constructor, use pointers, although … |
