In computer programming, a collection is an abstract data type that is a grouping of items that can be used in a polymorphic way. Often, the items are of the same data type such as int or string . Sometimes the items derive from a common type; even deriving from the most general type of a programming language such as object or variant .
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.
C++ has enumeration types that are directly inherited from C's and work mostly like these, except that an enumeration is a real type in C++, giving added compile-time checking. Also (as with structs), the C++ enum keyword is combined with a typedef, so that instead of naming the type enum name, simply name it name.
In object-oriented programming, the singleton pattern is a software design pattern that restricts the instantiation of a class to a singular instance. It is one of the well-known "Gang of Four" design patterns , which describe how to solve recurring problems in object-oriented software. [ 1 ]
In compiler design, static single assignment form (often abbreviated as SSA form or simply SSA) is a type of intermediate representation (IR) where each variable is assigned exactly once. SSA is used in most high-quality optimizing compilers for imperative languages, including LLVM , the GNU Compiler Collection , and many commercial compilers.
All new types are defined in <inttypes.h> header (cinttypes header in C++) and also are available at <stdint.h> header (cstdint header in C++). The types can be grouped into the following categories: Exact-width integer types that are guaranteed to have the same number n of bits across all implementations. Included only if it is available in ...
Welsh has two systems of grammatical number, singular–plural and collective–singulative. Since the loss of the noun inflection system of earlier Celtic, plurals have become unpredictable and can be formed in several ways: by adding a suffix to the end of the word (most commonly -au), as in tad "father" and tadau "fathers", through vowel affection, as in bachgen "boy" and bechgyn "boys", or ...
The following example demonstrates various techniques involving a vector and C++ Standard Library algorithms, notably shuffling, sorting, finding the largest element, and erasing from a vector using the erase-remove idiom.
