4 Better modern C++: Additional topics

Modern C++ has expanded the range and depth of functionality available for developers. Many areas have improved, and well-designed and articulated recommendations have entered the standard. This chapter is a very sparse sampling of a few features that make everyday programming simpler, more correct, and easier to read.

Almost any C++ developer would benefit from these additional topics but argue that some crucial aspects have been overlooked. This assessment is correct, since there are too many nifty features to enumerate. However, consider this effort a starting point in a general approach to picking up some handy improvements.

Text handling has improved, using the not-yet-implemented-everywhere format header. Parsing text by writing your code is fraught with complexity and errors, but regular expression functionality simplifies developers’ lives.
