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?

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 ...

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...
