 | [url]http://faq.cprogramming.com/cgi-bin/smartfaq.cgi?answer=1044842972&id=1043284392[/url] Same principle for C You separate the implementation (in a .c file) from the interface (in a .h). Everything else includes just the interface, and the implementation is in just one place. Also, stop calling your C programs with a .cpp extension. That will just lead you astray. |

| | Well there is [ICODE]std::sort[/ICODE], which will work on a [ICODE]std::vector[/ICODE] of integers. If you know what you're doing, it would take about 10 minutes to write - is that quick enough?

Pick a language and stick to it. Despite their recent common ancestry, and superficial similarity, using both of them well requires a C++ hat AND a C hat. C/C++ is just brain-damage. > … |
| | Re: Just wondering Other applications seem to manage it when they want user attention. So I'm going with "yes" as being the answer to your question, it is possible to do that.  |
| | Cut and paste works, as a bootstrap to get you going. If you have [ICODE][COLOR="Red"]int array[2][3][4][/COLOR];[/ICODE] and you want to pass that to a function, then you simply do [CODE] void myFunc ( [COLOR="Red"]int array[2][3][4][/COLOR] ); // prototype void myFunc ( int array[2][3][4] ) { // definition array[0][0][0] = 0; … |

| | I'm wondering something too. Like how are we supposed to guess which OS / Compiler / UI Toolkit you're using from just a few UI buzzwords scattered through the post and 2 lines of code. |
| | Perhaps begin with a simple program which reacts to single key presses. Then write another program to implement the basic queue data type. Then come back to us.  |
| | And you'd still get posts in it from the Turbo C luddites as well. Most of the time, they don't have a clue what their question is. Is it an OS question, a C++ question, a compiler question or an API question?. They just scan the forum titles (ignoring the … |

| | So what's YOUR question? Mine is "Why haven't you read the intro posts on how to use code tags?"  |
| | Yes, we all can solve it. The question is, are you going to attempt it yourself first? That's what the intro thread tells you.  |
| | Why did you ignore ALL the places which tell you about code tags? |
| | SS means stack segment. EBP typically moves around with ESP (BP=Base Pointer, SP=Stack Pointer). The BP is typically used to establish a fixed point of reference for a stack frame. BP + offset would typically be parameters, BP - offset would be local variables and temporary storage. |

| | > The original code takes in a url as an argument. The first argument will be argv[1]. argv[0] is traditionally the program name. Also, rather than assuming that argv strings can be modified, just make a copy of it in a variable you KNOW you can modify. It's not like … |

| | But "Fred Flintstone" reads as "Fred Flintstone" to anyone smart enough to use a hex editor. Sure, if you write enough other binary data along with it, most simple text editors will barf on the file, but no hex editor will. You could try encrypting the file, but by necessity, … |
| | Why not simplify, and just write the whole file? Unless you're incrementally adding (always) to a file which is many megabytes in size, this isn't going to take much longer than any other approach. Or how about a boolean, which records whether a header exists in the file (or not). …  |

| | 1. 13! overflows an int. So unless you're keeping to really small values, expect trouble here. 2. (numerator/denominator) If both of these are ints, the result is integer division (truncation towards zero, result is an integer). Cast one of them to double before dividing, not afterwards. |

| | You only need the [ICODE]extern "C"[/ICODE] if you're mixing C and C++. If it's all C++, then [ICODE]extern [/ICODE]should be fine. Post actual code and error messages if you're still stuck. |
| | Well the implication from the text is that argv[1] is the "document???.cry" file. How about posting the code which verifies that an argument exists and then goes on to open the file and read it's contents (much like you do with cin at the moment). |
The End.
