Getting the first and last day of a month, using a given DateTime object
...
@SergeyBerezovskiy I'd hate to raise this point but don't you lose the timezone information when you new up a DateTime like this? Whatever timezone info was attached to the original DateTime instance is lost when you make a new instance like this.

How does delete[] “know” the size of the operand array?
...his information should not be available to the programmer. I can pass a pointer to a function and free it, but to get the size myself in that same function I have to pass around an extra parameter. Does that make any sense?

JSON.stringify without quotes on properties?
...
So, what you are looking for is basically an object inspector not a JSON converter. JSON format specifies that all properties must be enclosed in double quotes. Hence there will not be JSON converters to do what you want as that is simply not a JSON format.Specs here:

Memory footprint of Haskell data types
...= Uno a
data Due = Due a b
an Uno takes 2 words, and a Due takes 3.
The Int type is defined as
data Int = I# Int#
now, Int# takes one word, so Int takes 2 in total. Most unboxed types take one word, the exceptions being Int64#, Word64#, and Double# (on a 32-bit machine) which take 2. GHC act...
Why can't variables be declared in a switch statement?
...
Case statements are only labels. This means the compiler will interpret this as a jump directly to the label. In C++, the problem here is one of scope. Your curly brackets define the scope as everything inside the switch statement. This means that you are left with a scope where a jump ...
How can I get nth element from a list?
...untime error. It could very easily be avoided if !! had the type [a] -> Int -> Maybe a. The very reason we have Haskell is to avoid such runtime errors!

Why can I not push_back a unique_ptr into a vector?
... guarantees that a single unique_ptr container has ownership of the held pointer. This means that you can't make copies of a unique_ptr (because then two unique_ptrs would have ownership), so you can only move it.
Note, however, that your current use of unique_ptr is incorrect. You cannot use it ...
Possible to iterate backwards through a foreach?
...also an essential part of modern iterator-based programming. Perhaps the point is that it would be clearer/safer if there were two distinct keywords, to clarify whether one is asserting that the iterations are order-independent? [Given a language like Eiffel that can propagate contracts, such assert...
Differences in boolean operators: & vs && and | vs ||

Those are the bitwise AND and bitwise OR operators.

int b = 4; // 100

int c = a & b;

// Bitwise OR
int d = a | b;
