What are bitwise shift (bit-shift) operators and how do they work?
...t; is not an operator, because it would be redundant.
Also note that C and C++ do not distinguish between the right shift operators. They provide only the >> operator, and the right-shifting behavior is implementation defined for signed types. The rest of the answer uses the C# / Java operat...
D Programming Language in the real world? [closed]
...y small, self-contained processes, so interop with large amounts of legacy C++ code is not really necessary or useful. Thus D can get its foot in the door.
I think D will continue to gain grass-roots followers in this way -- on smaller projects that for whatever reason can afford to ditch the C++ ...

What is 'Pattern Matching' in functional languages?
...= Infinity;

f(x, y) = (double)x / y;
Hey, C++ supports pattern matching too.

static const int NegativeInfinity = -2;
static const int NaN = -3;

Why is “while ( !feof (file) )” always wrong?
...ue for essentially all the I/O APIs, whether it be the C standard library, C++ iostreams, or other libraries. As long as the I/O operations succeed, you simply cannot know whether further, future operations will succeed. You must always first try the operation and then respond to success or failure....
What is memory fragmentation?
...e heard the term "memory fragmentation" used a few times in the context of C++ dynamic memory allocation. I've found some questions about how to deal with memory fragmentation, but can't find a direct question that deals with it itself. So:

Difference of keywords 'typename' and 'class' in templates?
...above -- it is not interchangeable with typename in this case (note: since C++17 both keywords are allowed in this case).
You also must use class when explicitly instantiating a template:
template class Foo<int>;
I'm sure that there are other cases that I've missed, but the bottom line is:...
