    Syntax Style

    Hi,

    just a question of style, am I right in thinking these two are the same

    *(my_array) = NULL;
    my_array[0] = NULL;

    and these two

    *(my_array + i) = NULL;
    my_array[i] = NULL;


    I am used to seeing the second of each pair, but have only just spotted the other two in a program I am reading at present;



    tia,

    They are the same. The first in each pair directly works with the pointer that is the beginning of the array. The second in each pair works directly with array subsripting. The first is an example of pointer arithmitic.
    While you're breakin' down my back n'
    I been rackin' out my brain
    It don't matter how we make it
    'Cause it always ends the same
    You can push it for more mileage
    But your flaps r' wearin' thin
    And I could sleep on it 'til mornin'
    But this nightmare never ends
    Don't forget to call my lawyers
    With ridiculous demands
    An you can take the pity so far
    But it's more than I can stand
    'Cause this couchtrip's gettin' older
    Tell me how long has it been
    'Cause 5 years is forever
    An you haven't grown up yet
