Matching Subexpressions (XML)


	/** In this example, the regular expression /<(.)>(.)</(\1)>/ searches for
	* any number of any characters in angle brackets, any number of any characters
	* in after the angle brackets, and then finally a forward slash followed by
	* any number of any characters, again in angle brackets. This thus forms the
	* XML tags search expression.

jflopezfernandez / New line replacement for std::endl, by Dietmar Kuhl

Last active May 7, 2018 11:40


	/** Dietmar Kuhl, the C++ IO and Internationalization expert, wrote this blogpost
	* (https://kuhllib.com/2012/01/14/stop-excessive-use-of-stdendl/)
	* discussing the need to stop overusing `std::endl`. In the blog post, he implemented
	* this function as a replacement.
	*
	* While it looks almost exactly the same in use, this function only outputs a
	* new line character; it does not flush the output stream. In contrast, `std::endl`
	* both outputs a new character and calls `std::fflush()`.
