    I typed strcmp into google, and this was the top search result:

    Returns an integral value indicating the relationship between the strings:
    A zero value indicates that both strings are equal.
    A value greater than zero indicates that the first character that does not match has a greater value in str1 than in str2; And a value less than zero indicates the opposite.
    So seriously, STFW!!!

    Why do you think so? They have only 2 words in common.
    All problems in computer science can be solved by another level of indirection,
    except for the problem of too many layers of indirection.
