    written command line game "mastermind"

    hi all,

    i've written a command line based game called "mastermind". i think most of you know the game from our early days..

    well i've written my own and i would like to know what you guys think of it.

    here's the game:
    Mastermind.c
    Code:
    /* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * 
    *                                                                                  *
    *  File: Mastermind.c                                                              *
    *                                                                                  *
    *  Purpose: a nice little game which challenge you to use your mind and find the   *
    *           secret number...                                                       *
    *                                                                                  *

    [edit]
    changed the source to get rid of some bugs, changed the charset from 0-9 to 1-6 and max tries from 10 to 8, this way the game is more playable...
    [/edit]

    [edit2]changed the source again, there were some possible buffer overflows which i had to remove, thanks to capi from www.security-forums.com for helping me locate them

    Nice little right up, if I have the time, I will port it to perl sometime later. I have actually never played mastermind.

    I don't feel like counting, but how many lines of code were there to that program?

    i get errors when i try to run this.......im working with it now trying to see if its programming or user error *most likely user error*....il post back in a few with what errors i get
    work it harder, make it better, do it faster, makes us stronger

    try the new source, perhaps it does work now, i've tried to make it as general as possible (compatible with windows, linux), but maybe i've still missed something...
