    Ugh. I hate that. I can see the minor potential benefits, but god it's awful and completely unnatural :~

    I don't really see much of a difference, so i use it. What is it that you find unnatural? (now on the other hand, i absolutely hate "safe" code that looks like this: if((((a/b)+c)==(d))||(((a*c)+b)==(z))) - i can understand not being entirely clear on operator precedence, but at some point you'd hope they'd stop typing and read up on it)

            This would solve all your problems :-

            class T
            {
            . . .
            bool operator = (const T& t)
            {
            return operator ==(t);
            }
            . . .
            }

              Well thanks everyone for your suggestions to turn up the warning level. The reason I didn't catch it before is because I'm using a class that someone else wrote that uses lots of old string functions. And when I build it, the output window gets filled with warnings about how this function is unsafe, and that function is unsafe, and this function will make your machine blow up, etc.! Thanks! Rich

                      That's nothing. Years ago, I spent half a day figuring out why this loop only exected one iteration:

                      for (int i=0; i<10; i++);
                      {
                      ... do something
                      }

                      BTW, isn't there a compiler warning for "are you sure you want to do an assignment here? Is your warning level set to the highest level? Marc Pensieve

                      Actually, doesn't that warning come out at level 3?

                        Well, at least I would write it as:

                        if((((a / b) + c) == d) ||
                        (((a * c) + b) == z))

                        I learned C back in the day when operator precedence enforcement was hit-or-miss in some compilers (yes, I'm that freakin' old). I was also programming in FORTRAN, Ada, and LISP at the time. It was just too bloody hard to remember the different rules for each language, so I learned to fully parenthesize. It could be worse. Here's an example of the coding style of one of my coworkers:

                        if (x == 2 || x == 6 && y > 5) for (int i = -1; i < 10; ++i)
                        InvokeMethod(i,x,y); else InvokeMethod2(x);

                        He avoids braces '{}' and parentheses whenever possible, and just strings everything together on one line like a sentence. He's also one of these object-oriented-out-the-wazoo types, who never puts more than four or five lines of code in a single function. His code is almost impossible to follow. The only saving grace is he does adhere to our naming conventions.

                          Just wait. C/C++ has had thirty years to collect warnings and errors, not to mention rules that makes it difficult for them to be specific and clear. C# will get there[^] too...

                                    Don't feel too bad. A few companies ago, I was working on my code, and it kept crashing. The company was a startup, so we were under the gun, naturally, with an impossible deadline to meet. Needless to say, I'm banging my head against the wall trying to find what I did wrong, and not getting anywhere. Fast forward 3 hours later, it's 2:30 AM and I'm in the debugger, deep in the code of one of the other guy's in the company (the lead app coder/engineer/wank/whatever) code, that integrates with mine. Turns out he had written:

                                    if ( id == id ) {
                                    //do some stuff
                                    }
                                    else {
                                    //do some other REALLY, REALLY important stuff
                                    //that should have been flagged in his own testing,
                                    //if the retard had ever bothered to do so in the
                                    //first place!!!!
                                    }

                                    So 2:30 AM, I can't actually fix the problem, but I have now wasted ALL my evening and productivity chasing down someone elses lazy coding (I say lazy because the nature of this particular logic error meant that his code NEVER worked right in the first place). Man was I pissed. This same guy, let's call him "Biff", drove so many of the other developers nuts, created so many software problems, that a few months later, we all got together and talked to the CTO. We basically said, either he goes or we all go. So the CTO makes an announcement the following day: Biff was offically promoted to Project Lead. :(( :(( :(( ¡El diablo está en mis pantalones! ¡Mire, mire!

                                      Is 1 == 2 more natural than 2 == 1?

                                      Have you ever compared two constants? Cheers, Vikram.

                                        I don't know whether I should laugh or cry at that. :suss: Either way, you have my sympathies. Cheers, Vikram.

                                          I don't really see much of a difference, so i use it. What is it that you find unnatural? (now on the other hand, i absolutely hate "safe" code that looks like this: if((((a/b)+c)==(d))||(((a*c)+b)==(z))) - i can understand not being entirely clear on operator precedence, but at some point you'd hope they'd stop typing and read up on it)

                                          Try saying it out aloud "if i equals 2" versus "if 2 equals i". Yes, semantically it means the same, but in natural speech, you always put the thing you're comparing first, and the standard you're comparing against second. I find code is a lot easier to understand if it reads nicely.
