c - comparing 2 char variables - 


int compare (char * s, char * pre)  {     int x = 0;     char p;     char orig;     while (pre[x] != '\0')     {        printf("%c", tolower(pre[x]) );       printf("%c", tolower(s[x]) );       orig = tolower(s[x]);       p = tolower(s[x]);       if (orig != p);        {           return 0;       }        x++;     }      return 1; }

expected return : 1 (values identical till end of loop) resulted return : 0 (values don't match)

this tautology: 

orig = tolower(s[x]); p = tolower(s[x]); if( orig != p ) etc.

probably? should be:

orig = tolower(s[x]); p = tolower(pre[x]); if( orig != p ) etc.

note ; removed if stmt.
