Expression templates thus allow programmers to bypass the normal order of evaluation of the C++ language and achieve optimizations such as loop fusion. Expression templates were invented independently by Todd Veldhuizen and David Vandevoorde; [ 2 ] [ 3 ] it was Veldhuizen who gave them their name. [ 3 ]
The Parallel Patterns Library is a Microsoft library designed for use by native C++ developers that provides features for multicore programming. [1] It was first bundled with Visual Studio 2010 . It resembles the C++ Standard Library in style and works well with the C++11 language feature, lambdas, also introduced with Visual Studio 2010 .
The loop calls the Iterator::next method on the iterator before executing the loop body. If Iterator::next returns Some(_), the value inside is assigned to the pattern and the loop body is executed; if it returns None, the loop is terminated.
The loop counter is used to decide when the loop should terminate and for the program flow to continue to the next instruction after the loop. A common identifier naming convention is for the loop counter to use the variable names i, j, and k (and so on if needed), where i would be the most outer loop, j the next inner loop, etc. The reverse ...
In computer science, a generator is a routine that can be used to control the iteration behaviour of a loop.All generators are also iterators. [1] A generator is very similar to a function that returns an array, in that a generator has parameters, can be called, and generates a sequence of values.

The curiously recurring template pattern (CRTP) is an idiom, originally in C++, in which a class X derives from a class template instantiation using X itself as a template argument. [1] More generally it is known as F-bound polymorphism , and it is a form of F -bounded quantification .
