Everyone knows they should always be placed on the same line! All your code should look like this:
if (isTrue()) { for (int i = 0; i < SomeNumber; i++) { int q = i; DosomethingWithQ(q); } PrintSomething(); };P

Guidelines I've come across usually split into recommended and mandatory. Then the things which people disagree over are put in recommendations. But really guidelines, e.g., for C++, should concentrate on the kind of stuff in Scott Meyers's Effective C++ books.
I don't disagree with that one bit. Its just been my experience that it hasn't worked out that way (and it should be noted that in the first case, I was the only one who was even vaguely familiar with Meyer's books ... much less Robbins, Sutter, etc). I've even had objections arise when I tried to make a case for always forcing code to compile on the highest warning level with 0 errors/0 warnings before being checked in to version control (which is something I always thought should be a given).

According to Francis Glassborow of the Association of C and C++ Users (ACCU), most programmers don't read books on programming, so I'm not surprised. He told me this in an email after he'd wriiteen that he'd lent a colleague Effective C++ and it had been returned unopened.

In C# if statments can only evaluate booleans so if(x=5) would not give it a boolean and cause a compiler error.

Just like you don't use a hammer when you need a screwdriver, you don't use C# (or Java or VB) when you need C++.

Check out the Microsoft research project called Singularity. Its an operating system written in C#. Around %99 of it(including the kernel) is written in C#.

Yes, Java was a good start and had the right idea. C# can do more. .NET allows any language to be compiled to the .NET platform.
static int Sqrt(int x) { if (x<0) throw new ArgumentOutOfRangeException(); int temp, y=0, b=0x8000, bshft=15, v=x; do { if (v>=(temp=(y<<1)+b<>=1)>0); return y; :omg:

Talking about errorprone statements ;P btw, I have never thought of that, not even after I had this error happen five times in a 500k lines application. Good tip, will keep that in mind and ask the quality manager to add it to the code convention.

Yaaarrrr What about weapons of mass-construction? -

You her a multitude of voices from all directions shouting: "For that you will burn on the stake, heretic!" ;P Thats what is fundamental about coding styles: When you have three programmers together, there are at least four stlyes assembled.

Which explains why there are so many horrible programmers running around getting paid to do their worst ...

Sun tried to do this with Java a few years ago. It failed and for good reason.

Don't get me wrong, there are some nifty features in the .Net framework. That said, managed languages are very limited in their scope of applications. Garbage collection, no matter how efficient the algorithm is, will always be slower than optimizing your memory usage based on how you are using it. I haven't done a whole lot with C#, but I do a lot in Java. C++ is like having a whole general purpose toolbox while Java/C# is like having a nice screwdriver set.

The Singularity project is going quite well. It is very interesting, check it out.

When they produce an OS that is both stable and efficient enough to compete with a native OS, then I'll look more into it. As it stands right now, it is just another in a line of attempts to use "lazy languages" to do things they weren't designed for. I've seen this fail twice in the past (with both Sun and Microsoft).
