    Re: Order of operation on multi core hardware

    OK thanks everyone for your replies. I think it is pretty much as I expected - order of execution is not guaranteed. Again, thanks for taking the time to answer.
    Cheers,

    Order of operation on multi core hardware

    Hello,
    On a multi-core machine, am I guaranteed to have my code executed in the precise order it was written?

    Is this safe?

    The following code fails as expected because I am passing an invalid pointer:


    void func2(char* c, char* d) {
    c = d;
    }

    void func() {
    char* c = NULL;
    char* d = new char('f');
  4. Re: Console exits before I get a chance to see the output

    As for your intellisense issue, try deleting your project's .ncb file. It's probably in the same folder as your project file. That should force VS to regenerate the intellisense. It's an issue that...

    Re: Need to return a *char not address of...

    First of all your function is not set up to return a const char. You need to declare it thusly:


    const char *ftostr(float dVar) {...}


    Secondly, you are returning a pointer to a local...

    Re: Another design question

    Hi monarch_dodra,
    I considered this as an option, but I have a hunch it's going to to get me into hot water because whenever I have to perform one of these mutually exculsive operations I will have...

    Re: Another design question

    Thanks Russco,
    That was my initial plan. I just thought I'd see if anyone had other ideas. The problem I have with that method is I have to query the object to see what type it is. I was hoping to...

    Re: Another design question

    @Lindley
    Yes, I do plan to treat them as the same type of object - they basically are. It's just that in their specialisation there are a couple of mutually exclusive operations.

    Another design question

    Hi all,
    I have a design issue and want to get some feedback on solutions.

    I have two classes, let's call them A and B. They have very similar interfaces and are 98% polymorphic. It is in the 2%...

  14. Re: Looking for a neat way to accomplish this type problem

    Yes. Hence the question.

    @John
    Thanks for that. From the quick look I just had it seems spot on. I will have a proper look when I get back to work tomorrow.

    I have a design issue which I've had in the past and never really found a satisfactory solution for, so I was hoping to get some fresh ideas on how to handle it.

    Re: Change stupid indent style

    There are times where bracing in case branches is necessary such as the following. Case 1 is how I like to format my braces. Case 2 is how Visual studio lays it out. I find the second way much harder...

    Re: Change stupid indent style

    Thanks Mike. Yes 2005 has that option - I have it unchecked, but it doesn't seem to govern the bracing in switches.

    I just don't know where VS got this indent style from and why it only applies it...

    Change stupid indent style

    Visual Studio (2005) automatically indents braces for each case in switch statements in what I consider to be the most impossibly idiotic manner. I have always ignored it and fixed it manually but...

    Re: * 8 vs

    The compiler (certainly VStudio anyway) generates the same code for both cases so there is no performance gain in shifting over multiplying.

    I agree with both superbonzo and D_Drmmr. I try to pick...

    Re: Static array allocation problem

    As Lindley says, that's the way arrays on the stack work. When you write:


    int myarray[] = {5, 6, 7};

    You are creating a memory block three ints long. The address of that block is myarray[0]...
