    Exclamation Help Please!

    I was wondering how I can take a string entered in and separate it so I can use individual characters.
    user enter in "3 + 4 + 8 * 9 / 3 + 4"
    I want to get all those characters seperately and then be able to apply the order of operations.

    I'm not finding much out in any of the books I have.
    Any help will be very appreciated.

    If the user is entering it all as a string, then you will need to tokenise your string. 'strtok' is useful for this. Everybody has a preference but that's an OK place to start.
    Demonographic rhinology is not the only possible outcome, but why take the chance

    You can calculate arithmetic expressions by converting it from infix to postfix form.

    eg. infix : 3+4

    postfix : 34 +

    The algorithm for this is available in Data structure books,preferably by tremblay and sorenson.
