    You should get at least a warning that atof() isn't declared properly in numcmp.c.

    And this also looks strange:


    //numcmp.c
    void substr(char *s, char *t, int maxstr);
    ...
    //substr.c
    void...

    if ( num % 9 >= 0)

    This expression will always be true. % 9 returns the remainder of the division by 9...

    No, that line is syntactically correct. %[ is a legal format specifier. See scanf, fscanf, sscanf - cppreference.com.

    while(str[i++]!='\0');

    When str[i] == '\0' you are still incrementing "i".
    You need to increment "i" in the body if you don't want to count the '\0'.

    This will print the fourth letter (after changing %s to %c of course). Remember array indexing starts at 0.

    You should already have mingw32-make on your system.
    So just use it instead of make (which is the MS make).
