    beginner question about strings

    Hey, new here
    I have a problem.

    I need to read in a string of chars (upper/lower case letters and punctuation marks : '.' or ',' or ';' or '?' or '!') of unspecified length, then take each one of the words and process some calculations such as : average length of a word, average vowels in each word, how many words are between 10 and 15 letters long etc..

    An example input would be:
    Hello there! How are you?

    I read a string in using the keyboard and I use strtok from the <string.h> library to break the string down to individual words. The problem is that the words in the string can be seperated by any white space characters not just by the spacebar.
    Iam using something like :
    char line[MAX_SIZE];
    strtok( line, " ");
    so I can break the string into words. But I am only limited to words that are seperated by the spacebar " ".
    How do I take each word seperately from the input string and run the calculations on it ?


    Thanks in advance

    My problem is input like this:

    Hello [tab] there how are [tab] you doing?

    because strtok( string, " "); takes a space as an arguement, my program will break down the string everytime it finds a single space as follows:

    Hello [tab] there
    how
    are [tab] you
    doing?

    I want it to be:
    Hello
    there
    how
    are
    you
    doing?

    thanks

    Edit: i dont know how to display tabbed text in the forums so where u see [tab] it means the user hit the tab button

    You can put multiple things in your tokenizer string. You might want something like " \t\n".
