How many people actually have had a bug in their code caused by an incorrect assignment; = instead of ==??? It was just a while back while reading a PHP article the author suggests ALWAYS using a fixed number/value (if you can) then the == operator then another variable or fixed value so instead of:
if(a==2)
you get:
if(2==a)
Remembering to always use this method when using == will prevent you from ever making and assignment error, becuz obviously the complier catches 2=a as an invalid assignment, whereas 2==a is cool. Personally I can honeslty say i've never made that mistake yet...it was one of the first things I read when I was learning how to program...becareful with assigment and equality operators...and I always have been since then...however I still want to try and get into the habit o fusing this technique...just becuz it's one less bug to ever have to worry about...which is great news, cuz I hate getting stuck for more then 10 mins on a bug. Anyways, just curious...how many of you actually have made that mistake before...??? How do I print my voice mail?
Set the warning level to 4 and you will always get a warning.

A good compiler will issue a warning telling you that you may have used assignment instead of comparison. Therefore I think that the style you mentioned makes code unreadable and is not worth it. Drinking In The Sun Forgot Password?

Ahhh...is that how you do it... :) Cooly i'll try that... How do I print my voice mail?

Actually there is such feature in C++, see page 829 in Appendix C in the book "The C++ Programming Language, 3rd", except operator==. We can write our C++ code this way by turning on /Za.
bool bFlag = false;
if(not bFlag) { /* Do something... */ }Regarding to the *missing* alternative keyword, we may define this
#define equal ==
for
if(bFlag equal true) { }

This is the best solution, IMHO. Regards, Jeff Varszegi EEEP! An Extensible Expression Evaluation Package

Very occasionally if I haven't had enough coke in the mornings I'll slip one of those in, but the compiler warns me about a possible mistake and lets me fix it before it gets anywhere. Like Jeff, my causing problem is not registering two key presses successfully - my brain works faster than my fingers!

Coming from a VB background, I have never made that mistake since my third year C++ COS module, but now I work in C#, and nearly always use the constant first format. The funny thing is, on Friday just after I explained its use to my colleague, I found one such error in a piece of my code which I had too hastily added. Fortunately I spotted in even before compiling, but it did make me slow down a bit. After all, this was code calling the RegistryKey.DeleteSubKeyTree method. My blog.

if ((res = testSomething(foo)) == 100)
{
// alert the authorities

Not once since I started working in C# :P (yeah, yeah - I know the new compiler will trap this potential error but I felt the need to spout some MS kool-aid this morning ;)) cheers, Chris Maunder

I do it very very often but I almost always catch myself when im closing the braces ) :) I read about 2==a in Deitel a few years back but don't like it since I like to execute something inside my condition and then check if it's equal ot something. " Why oh why didn't I take the blue pill ? "

That sounds so simple! It just feels so weird to write it like that. I guess my ingrained habits are going to cost me time spent debugging (because yes - I have had these bugs).
