    size_type is meant to hold an unsigned integral. That's about it. There's no other assumption made.

    This number must be big enough to hold the maximum number of characters a string can hold.

    Since a string maximum lenght is machine/implementation dependant, the size_type companion type was created (as a typedef) to support machine-independant behavior. It can be an int, a long, the number of extra-marital kids the library implementator had at that time.
    The programmer’s wife tells him: “Run to the store and pick up a loaf of bread. If they have eggs, get a dozen.”
    The programmer comes home with 12 loaves of bread.

    Well Turbo C++ 3.0 is about fourteen years old, so yeah, maybe it is.
    System: Debian Sid and FreeBSD 7.0. Both with GCC 4.3.

    Just get the good-old dev.

    Thanks for that info, Mario. Always informative! ... "the number of extra-marital kids the library implementator had at that time." .... right

    That's the way I would do it!

    Dev-C++ -- it's not fourteen years old
    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;}

    in turbo C I think you have to use STRNG.h because string is already taken for strlen(), strcpy etc. I think.
