    You'll find it all in the header described in this post. Instead of using disk, you'll need to subsitute scanner and parser.

    Hope is the first step on the road to disappointment.

    I looked underneath my chair - nothing.

    Have you considered actually trying to do the work yourself rather than merely competing with your class-mates to see who has the best google skills.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    GNU Bison and Flex. Probably more than you need*. Good luck.

    Heh, magic scanner/parser. Which reminds me...

    Code:
    #include <stdio.h>
    
    void J(char*a){int f,i=0,c='1';for(;a[i]!='0';++i)if(i==81){
    puts(a);return;}for(;c<='9';++c){for(f=0;f<9;++f)if(a[i-i%27+i%9
    /3*3+f/3*9+f%3]==c||a[i%9+f*9]==c||a[i-i%9+f]==c)goto e;a[i]=c;J(a);a[i]
    ='0';e:;}}int main(int c,char**v){int t=0;if(c>1){for(;v[1][
    t];++t);if(t==81){J(v[1]);return 0;}}puts("sudoku [0-9]{81}");return 1;}

    Yeah, like we haven't heard the "But I need one to compare with the one I've written" before.

    So start with the basics and work your way up like everyone else.

    Sure, you might find a scanner which does what you want, but how would you know whether it was "good C" to learn from?
