  • Hi,


    The first declaration:


    *pd += (double)*pi


    are not correct so far that the variable pd

    has no memory reserved.


    The same with *Pj /= 3;


    If you do first;


    pd = new double;

    pj = new int;


    than you can operate with pd and pj

    and there are no access violation.








  • : pd = new double;

    : pj = new int;


    : than you can operate with pd and pj

    : and there are no access violation.


    If you're going to be advocating doing this, then perhaps you should suggest making sure that 'delete pd' and 'delete pj' occur somewhere later in the code. Y'know, just for clean coding's sake. :)
