    Question Some Help for Finals

    hello im new here and have scouted the internet and i like this page alot.. so i signed up and will probably read more so than post but i did have some questions, really basic stuff for a final tommrow any help would be great thanks soo much!!
    -------------------------------------------------------------------------------
    ok,
    in order of operations what comes first || or &&?
    also in order of operations what is first == or !=?


    finnally some loop stuff, i understand the code pretty decently i just dont know how many times the loop will be executed
    eg:

    int a = 10;
    int x = 4; ...oops

    do
    {
    cout << a << " --- " << x;
    cout << endl << "wow";
    }

    while (a<=x)

    ----------------------------------------------------------------------
    ... im guessing as long as "a" is less that or equal to "x"
    but what about like
    ----------------------------------------------------------------------

    int a = 20;
    int x = 4;
    while (x<=a)
    {
    cout << a << "---" << x;
    cout << endl << 'wow";
    a--;
    x++;
    }

    ------------------------------------------------------------------------
    i get lost here with the -- ++ stuff.. retarted i know..
    again any help is much appritiated and if no help well i just will go and stare at my book for along time sniff

    && comes before ||, == and != are the same, there's no telling because you don't know what x is, and 9.

    When in doubt use parenthesis. You should try and use parenthesis anyway since it makes you code more readable.
