Unlike vector, deque uses discontiguous blocks of memory, and provides no means to control the capacity of the container and the moment of reallocation of memory. Like vector, deque offers support for random-access iterators, and insertion and removal of elements invalidates all iterators to the deque.
It is, however, preferable to use an algorithm from the C++ Standard Library for such tasks. [1] [2] [3] The member function erase can be used to delete an element from a collection, but for containers which are based on an array, such as vector, all elements after the deleted element have to be moved forward to avoid "gaps" in the collection ...
The STL was created as the first library of generic algorithms and data structures for C++, with four ideas in mind: generic programming, abstractness without loss of efficiency, the Von Neumann computation model, [2] and value semantics. The STL and the C++ Standard Library are two distinct entities. [3]
The C++ Standard Library is based upon conventions introduced by the Standard Template Library (STL), and has been influenced by research in generic programming and developers of the STL such as Alexander Stepanov and Meng Lee. [4] [5] Although the C++ Standard Library and the STL share many features, neither is a strict superset of the other.
Here, c[i:i+3] represents the four array elements from c[i] to c[i+3] and the vector processor can perform four operations for a single vector instruction. Since the four vector operations complete in roughly the same time as one scalar instruction, the vector approach can run up to four times faster than the original code.
Anti-Grain Geometry (AGG) is a 2D rendering graphics library written in C++.It features anti-aliasing and sub-pixel resolution.It is not a graphics library, per se, but rather a framework to build a graphics library upon.
3DMLW – Scene description languages (3D vector image formats) STL – Stereo Lithographic data format (see STL (file format)) used by various CAD systems and stereo lithographic printing machines. See above.
The C standard library, sometimes referred to as libc, [1] is the standard library for the C programming language, as specified in the ISO C standard. [2] Starting from the original ANSI C standard, it was developed at the same time as the C POSIX library, which is a superset of it. [3]
