    <strings.h>

    Anyone know where I can get that?
    I need the strncasecmp() function to compare two strings regardless of their case.

    I can't find it anywhere, and it doesn't come with my compiler im using.

    try stricmp() or strnicmp(). I'm willing to bet you have those functions.

    FAQ > How do I... (Level 1) > Where can I download a missing header file?

    <string.h> is a standard header, not <strings.h>, but strcasecmp is not a standard function. Writing your own is fairly easy. [edit]Take a stab at it before peeking at this.

    I don't have either of those functions.

    Im using strncmp() but I need something that will say the strings are the same if for example:
    1) This Is A String
    2) this is a string

    I need both of those to be compared and the function to return that they are the same. Right now the strncmp() does not do this.

    I only have the <string.h> header file, but in the <strings.h> file there is the strncasecmp(), in which I need.

    What compiler are you using?

    The linux gcc compilers in our computer labs have this header file, but my windows compiler does not have this, and I cannot get to the lab to grab it.

    I'm just using a compiler I grabbed off a site called PellesC.

    As, Dave said. It's easy to write your own. Look into <ctype.h> and the toupper() function. You don't go fishing around for nonstandard libraries when it's easy enough to write the code using standard libraries.

    Doesn't using non-standard headers defeat the whole purpose of writing portable C code (which made C famous in the first place)?

    I'm sort of a beginner at this but wouldn't stricmp() work?

    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;}

    Plese try to compile the following code and place error messages you're getting:
    Code:
    #include <stdio.h>
    #include <string.h>
    
    int main (void)
    {
        char str1[] = "Test";
        char str2[] = "test";
        
        printf ("%d", stricmp (str1,str2));
        return 0;
    }
    Gotta love the "please fix this for me, but I'm not going to tell you which functions we're allowed to use" posts.

    How he doesn't, I don't know, but regardless, it's simple enough to write one.

    Depends on your requirements.

    If portability is a requiement, yes.

    If it is not a requirement, or not particularly cared about, then no.

    Try _strnicmp() for MS compilers.

    The best solution is to write your own string comparison function.
