Why isn't `int pow(int base, int exponent)` in the standard C++ libraries?
...ype, then all arguments corresponding to double parameters are effectively cast to double.
So, basically, integer parameters will be upgraded to doubles to perform the operation.
Prior to C++11 (which was when your question was asked), no integer overloads existed.
Since I was neither closely ...
How should one use std::optional?
...at are provided purely to enforce intention) include the various C++ style casts, "const" (especially on member functions), and the "bool" type, to name a few. Arguably you don't really need these code features, so long as everyone obeys intentions or comments.

This leaves the program fragment shown as valid. The (void) cast prevents it being used in contexts where a value is required — but it could be used as the left operand of a comma operator where the do { ... } while (0) version cannot. If you think you should be able to embed debug...
Java 8 Iterable.forEach() vs foreach loop
...ator) and cannot be used in a for-each, only with a forEach(). I recommend casting Streams into Iterables with (Iterable<T>)stream::iterator. A better alternative is to use StreamEx which fixes a number of Stream API problems, including implementing Iterable.

// The factory method returns a XmlWriter, not a XmlTextWriter, so cast it.
XmlTextWriter xtw = (XmlTextWriter)XmlTextWriter.Create(ms, xws);

xtw.Formatting = Formatting.Indented;
// Now serialize our object.

I would have personally offered a char* const getter to string. Const pointer, but editable string. Although it may have messed with the implicit conversion from ...
