 | The 'comm' command allows you to find out - lines only on the left - lines only on the right - lines common Use this to extract a list of files which are common to both directories. |
| | Sounds interesting - you should have a lot of fun doing that. What do you need us for? |
 | > so why would one need to know assembly? Curiosity mostly. Being able to follow the code the compiler generates, and very rarely writing very small snippets works for me. |

| | Perhaps read up on ios::app means append Also, you open a file for output, then try to open it for input (does that even work?) |
| | What you describe happens all the time with almost every function, and it isn't a problem. Perhaps you mean the alternative of where T2 tries to call X(), while T1 is already in X(). That's re-entrancy, and is a far more interesting problem. And no, you can't just "test" to … |

 | But it's only low because the global economy has been torched, not because of some military "success" (or otherwise). I bet that aspect wasn't in the sales pitch for war. > Really, what's the cause of this steep decline of oil price? Same thing that drove it up. Actual supply …  |

| | And your point being what? That sometimes no matter how much you google, that you can't find a ready-rolled answer? What ever happened to trying your own homework. I imagine the point is to see who's learnt something, not who's got the best google skills.  |
 | [ICODE]g++ -c cppcode.cpp gcc -c main.c g++ -o test main.o cppcode.o[/ICODE] Oh, and that might not work either. This is how to mix C and C++ [url]http://www.parashift.com/c++-faq-lite/mixing-c-and-cpp.html[/url] In particular, the main() needs to be C++ so that global ctors/dtors get called. |

| | Re: C++ Vectors You need to pass references to the vectors you are expecting to be updated. Otherwise, it's just [code] void foo ( int a ) { a = 3; } int main ( ) { int b = 0; foo( b ); // b still 0 here, not 3 } [/code] … |
| | Use a for loop. That's pretty standard when you have an array, that is to use a for loop to iterate over the elements of the array. |

| | Do you have a manual for the C library functions? Are you using it? At the moment, you just seem to be typing in stuff without even beginning to think about what you're really saying. |

 | > int rePass(0); //first password Most passwords are strings, not int's > goto PassCheck; Use a while loop.  |
| | Use CreateProcess() It's the one native to your OS, and will ultimately give you the most control over what happens. Use system() if you require no more sophistication than would be provided by a batch file. In other words, very basic "run & forget" approach. |
| | You have to read up on the (sometimes strange) rules about quoting and variable substitution in various shells. Try say [ICODE]sed $i's/$/'$age'/g' birthday.csv[/ICODE] Or maybe [ICODE]sed "${i}s/$/${age}/g" birthday.csv[/ICODE] |
 | You have to allocate for each * in turn, starting with the outermost one, and working your way inwards. [code=c++] Graphics::Graphics() { Width = 10; Height = 10; TextArray = new char*[Height]; for ( int h = 0 ; h < Height ; h++ ) { TextArray[h] = new char[Width]; … |
| | Well the first thing you need to tell us is which OS you're using, and which compiler. As you've already discovered, this kind of direct access to the hardware is highly specific to your own circumstances. |

| | Re: Password Field > Again we really need more information Specifically, your operating system and compiler. And try to be more specific than say "windows" and "borland", as there are many versions of both. |
| | > Why should i put a ; ? Because it needs it. However, it might be better placed at the end of InputHandler.h (say at the end of a class declaration), rather than in your C++ code just to make the compiler shut up.  |
| | > whereas windows seems to place it in the middle of a system c-drive. In a single-drive system, you can easily get into the state of "swap a page out to disk, load a page of data for a program". This creates a hell of a lot of head movement. …  |
