 | Well since none of us attended your course, and apparently, neither did you, what exactly are you hoping to learn in the next 48 hours? Without knowing the syllabus ("algorithms" is just too vague), we could tell you some good stuff, but it would be still useless for your immediate … |

 | Well strcat does modify the string, and as written your code would almost certainly segfault if allowed to run. Stripping out (or avoiding) const because it's inconvenient is the wrong way to go.  |

A hard link isn't a copy of the file, but two directory entries pointing at the SAME part of the disk. Changing the file via one of them also changes the file … |

 | I would suggest you make everything else work before getting over elaborate on the user interface. Look at what you're required to do for the assignment and make sure you do that much first. If you've got time left at the end, then you can have fun making it look … |
| | Re: Need Help Make a backup of your code. Then keep chopping down the code until you've got something which is small, can be posted and still replicates the problem.  |
| | Re: CMD + C > FILE *fp=fopen("c:\\documents and settings\\test.txt","w"); Lemme guess, you're using Turbo C. It's no surprise really, everyone seems to for all the wrong reasons. One of these reasons being that it was written WAY (WAY) before long filenames, and spaces were allowed in filenames. This (and many other) compatibility horrors await … |

The only functions worth knowing are those in stdio.h, stdlib.h etc. Anything else (say conio.h and dos.h) has to be re-learnt every time you change OS/Compiler (which you'll do many times, so get used to it).

 | Asking on the relevant forum / mailing list for that project would be the sensible thing to do IMO. You'll find the highest concentration of people able to fix the problem, and who may have experienced something similar very recently (and thus be able to tell you what to do). |
