  1. Re: Pointers, passing by reference, and good 'style'

    IMO, pass-by-reference and pass-by-pointer accomplish the same thing. Mainly, to be able to modify/use some method parameter without copying it so that the changes are reflected in the calling...

    Re: calculating length of string

    a as you have defined it is a character array, and not a string object. Therefore, you cannot use the length() member function of that class to determine its length.

    Re: Problem after compiling

    The reason that your program just closes after you type in the name is because some IDE's do not automatically pause the program after execution so you can see the results.

    There are many...

    Re: memset question

    I think the solution from JMS is probably the best


    char buff[128];

    memset( buff, 'A', sizeof( buff ) -1 );
    buff[ sizeof(buff)-1 ] = '\0';


    Also, call me crazy, but I recall when...

    Re: C++ Pointers

    A lot of good points have been made here by the posters above, you should read them over.

    Not much else I can think of to add at the moment.

    All I can say is that when you start to work with...

    Re: Need "Urgent" help with a c++ program!!

    As stated above by the other posters, you need to at least attempt this on your own before we will help you.

    If I am understanding your question correctly, you are talking about interprocess communication.

    If this is the case, then yes it is possible. Well, to an extent anyways.

    Re: Linked List problem!!!

    I am starting to think that my college is the only one in the United States (perhaps the world) that teaches people how to use their debugger to solve coding problems.

    Re: to reduce footprint

    There may be some compiler optimization options to do so (at least for release build).

    But I would imagine if there are, then they are compiler dependent.

    Meaning, you would need to consult...

    Have you tried using your debugger?

    It is extremely helpful when your program compiles fine, but does not behave as you expect it to.

    You can check variable values, and set breakpoints to stop...

    Re: Problem with '

    I lost you on this line here.

    It doesn't make any sense.

    You can't just assign your struct the value of 128. Also, you already use the write() function, so what is the need for <<?

    Have you tried using your debugger to check variable values and such during your program's execution?

    You need to post all of your code.

    There is no way we can figure out what is wrong from this little snippet.

    And use [ code ][ /code ] tags when posting source code.
