The C++ Standard Library provides several generic containers, functions to use and manipulate these containers, function objects, generic strings and streams (including interactive and file I/O), support for some language features, and functions for common tasks such as finding the square root of a number.
Specifically, the for loop will call a value's into_iter() method, which returns an iterator that in turn yields the elements to the loop. The for loop (or indeed, any method that consumes the iterator), proceeds until the next() method returns a None value (iterations yielding elements return a Some(T) value, where T is the element type).
In object-oriented programming, the iterator pattern is a design pattern in which an iterator is used to traverse a container and access the container's elements. The iterator pattern decouples algorithms from containers; in some cases, algorithms are necessarily container-specific and thus cannot be decoupled.
The iteration form of the Eiffel loop can also be used as a boolean expression when the keyword loop is replaced by either all (effecting universal quantification) or some (effecting existential quantification). This iteration is a boolean expression which is true if all items in my_list have counts greater than three:
direct.h is a C/C++ header file provided by Microsoft Windows, which contains functions for manipulating file system directories. Some POSIX functions that do similar things are in unistd.h . Member functions
President-elect Donald Trump’s policy agenda is generally good for business, top executives and analysts told me at the Goldman Sachs Industrial and Materials conference this week. “It’s ...
The array container at first appeared in several books under various names. Later it was incorporated into a Boost library, and was proposed for inclusion in the standard C++ library. The motivation for inclusion of array was that it solves two problems of the C-style array: the lack of an STL-like interface, and an inability to be copied like ...
Eagles running back Saquon Barkley had a setback in his chase of the NFL season rushing record when he appeared slowed by an undisclosed injury. After topping 100 yards rushing in each of his last ...
