In C, do braces act as a stack frame?
...d is no longer eating up memory while your code is running, you can either convert the code in curly braces into a separate function or explicitly malloc and free the memory instead of using automatic storage.

What is the fastest/most efficient way to find the highest set bit (msb) in an integer in C?
...ack a leading-zero counting instruction, but some of those can efficiently convert integers to double. Type-punning an FP bit pattern back to integer can be slow, though (e.g. on PowerPC it requires a store/reload and usually causes a load-hit-store stall).
This algorithm could potentially be usef...
memory_get_peak_usage() with “real usage”
...ory alignment). It doesn't reflect memory wasted due to blocks not fitting into space remaining in already allocated segments. If you change your example to allocate (1024 * 256) bytes and a 2M limit, the difference of two will become more apparent.

How does Java handle integer underflows and overflows and how would you check for it?
... the syntax normally used when writing javadocs - while normally that'd be converted to Math.addExact, sometimes the other form just sticks around

How do I safely pass objects, especially STL objects, to and from a DLL?
...types (the bool specialization has a little bit of extra logic, since it's converted to a int8_t and then the int8_t is compared to 0 to convert back to bool, but this is fairly trivial).
We can also wrap STL types in this way, although it requires a little extra work:
#pragma pack(push, 1)

What are attributes in .NET?

Note: the above is C++/CLI but it's not difficult to convert to C#
(yeah, I know, C++/CLI is an abomination but it's what I have to work with :-( )
You can put attributes on most things and there are whole range of predefined attributes. The editor mentioned above also looks f...
Is it possible to send a variable number of arguments to a JavaScript function?
...used.
Also note that the arguments object is not really an Array, you can convert it by:
var argsArray = Array.prototype.slice.call(arguments);
And in ES6:
const argsArray = [...arguments] // or Array.from(arguments)
But you rarely use the arguments object directly nowadays thanks to the spre...
What are Scala context and view bounds?
...A <% Ordered[A]](a: A, b: A) = if (a < b) a else b
Because one can convert A into an Ordered[A], and because Ordered[A] defines the method <(other: A): Boolean, I can use the expression a < b.
Please be aware that view bounds are deprecated, you should avoid them.
