OK, my turn to learn something new: What's Dump()?
|
|
|
|
|
Dump() is an extension method added to all objects within LinqPad. LinqPad is a tool which allows writing & compiling simple C# code snippets (plus a bunch of other things). (And the basic version is free: www.linqpad.com )

It's an extension method provided by LINQPad[^].

Great tip and explanation. I am currently teaching myself C# and this is extremely helpful.

I needed the binary AND (was checking a flag register from a custom device) so it would have been a real issue if it did not compile

Depending on the correct implementation of the "&" and "&&" operators in a fat class it shouldnt be the same

Plain C operators - it was a stupid mistake from my part, on the same day I made at least 3 mistakes of >= vs >. It wasn just the day - in fact I'm on sick leave today due to a strong headache I've been coddling since yesterday evening. Probably I was starting to feel it's effects in the morning too

Heh, I'd like to use C# but as an embedded developer (using TI DSPs) it's not really an option for me. It's C/C++ or DSP assembly (which nobody in their right mind wants to do!!!!).

Actually, the result is the same. The side-effects aren't. At least in C#. In C, with it's enforced type-unsafety, the result can be extremey weird and the compiler won't do jack to even warn you.

No. Example
2 & 4 is 0
2 && is 1 (true)
In that case I needed the first form as I was checking for a flag in a flag register, but mistakenly used the second form due to, well, being the most common (althought not so much in my field, which requires the management of a lot of driverless hardware).

That depends on the language. In a strongly typed language, 1 and true aren't the same because one is a number and true is a boolean. So 2&4 is 0 and 2&&4 is 0 as well, however the difference is in side effects.
SomeFunc & SomeOtherFunc will execute both functions with their side-effets, SomeFunc && SomeOtherFunc will stop executing if SomeFunc returns false.
PS: I am talking about C# here which is, unlike C and C++, a strongly-typed language.

How this difference can hurt.
m is length of string = 3;
*b is first character in string say "xyz"
while( *b & m-- ) { b++; } is not the same as while( *b && m-- ) {b++;}
because
while( *b & m-- ) { b++; } fails when *b is null tested AND m is decremented at the same time ergo m is off by 1
while( *b && m-- ) { b++; } fails when *b is null tested. m is not decremented
because of the short circuit test of *b stops the evaluation
ergo m has the correct character count
so yes & and && are not the same so be careful of the logic when using C
