    getline to divide

    how would i?
    I have array of string which have the following:
    one meaning of one
    two meaning of two
    three meaning of three

    For example, "one" is a word and "meaning of one" is a meaning of one. How would I divide each line into two pieces so I can have word and meaning separately?

    I would like to use getline but don't know how to use it.
    I want to use a first space to separate those into word and meaning.
    Please let me know. thanks

    Use strchr to find the first space in a string.

    There are a number of ways to read up to the first space and then do something else. The easiest of which would be:
    Code:
    if ( fgets ( a, sizeof a, stdin ) != NULL ) {
      if ( sscanf ( a, "%s %[^\n]", b, c ) == 2 )
        printf ( "%s\n%s\n%s\n", a, b, c );
      else
        /* Report error and handle */
    }
    else
      /* Report error and handle */
    But a safer way would be to modify the input so that there is a delimiting character not in the real data which separates the strings that you want, like so:

    one : meaning of one

    You can then use the : as the separator. That way you don't have to worry about the spacing of the input, such as if someone forgets to put a space between "one" and "meaning":

    one-meaning of one

    This would result in "one-meaning" being the word entry and "of one" being the definition. Not quite what you want.

    My best code is written with the delete key.
