 | Do you want to delete it because it's line 2, or because it's green? Read up on the sed command. For example sed '2d' file > newfile or sed '/green/d' file > newfile |

| | Re: java vs .net One is a language (and some APIs) and the other is a platform specification. It's like comparing a car you drive to work with the road you take to work. The question seems meaningless to me. Neither depends on the other for their continued success (or otherwise). You're free to … |

| | > boost::ref(copy),x,structNum, boost::ref(n), boost::ref(bar) My first guess would be that you're passing references to data which subsequently change while each thread is running. |
| | As well as some.cpp, you also have some.h Which has say extern int some(); Main.cpp then has #include "some.h" And you compile main.cpp and some.cpp together. |
| | > lets say if the data file is empty and there is nothing to scan i got errors Well you need to pay attention to the return result of fgets() before you do anything else. |
| | Or just get used to using TEXT() macros all over the place, and stop worrying about what each revision of the IDE defaults to for character encoding. UNICODE isn't going away any time soon, so you're going to have to learn to deal with it. |
| | First thing I would check is that all the cables are correctly seated. You may have partially unplugged the master cable whilst removing the slave, resulting in erratic behaviour. |

| | You're mixing scanf() with fgets(). scanf() leaves a \n almost all of the time, then fgets() does "mmm, yummy, a \n. I'm done here". If you're going to use fgets(), use it for EVERYTHING, and then use sscanf() if you must. Or one of many ideas on flushing the input … |

| | The short answer is don't use scanf - period. Whilst it does what it says just fine, cleaning up when the unexpected happens is damn hard work (as you've found). Example [code] char buff[BUFSIZ]; if ( fgets( buff, sizeof buff, stdin ) != NULL ) { int myInt; if ( … |
