  2. Sequence container (C++) - Wikipedia

    en.wikipedia.org/wiki/Sequence_container_(C++)

    A typical vector implementation consists, internally, of a pointer to a dynamically allocated array, and possibly data members holding the capacity and size of the vector. The size of the vector refers to the actual number of elements, while the capacity refers to the size of the internal array. When new elements are inserted, if the new size ...

  3. Standard Template Library - Wikipedia

    en.wikipedia.org/wiki/Standard_Template_Library

    These types were left out of the C++ standard; similar containers were standardized in C++11, but with different names (unordered_set and unordered_map). Other types of containers bitset stores series of bits similar to a fixed-sized vector of bools. Implements bitwise operations and lacks iterators. Not a sequence. Provides random access. valarray

  4. Bit array - Wikipedia

    en.wikipedia.org/wiki/Bit_array

    Unlike the bitset in C++, the Java BitSet does not have a "size" state (it has an effectively infinite size, initialized with 0 bits); a bit can be set or tested at any index. In addition, there is a class EnumSet, which represents a Set of values of an enumerated type internally as a bit vector, as a safer alternative to bit fields.

  5. C++11 - Wikipedia

    en.wikipedia.org/wiki/C++11

    In C++11, a move constructor of std::vector<T> that takes an rvalue reference to an std::vector<T> can copy the pointer to the internal C-style array out of the rvalue into the new std::vector<T>, then set the pointer inside the rvalue to null. Since the temporary will never again be used, no code will try to access the null pointer, and ...

  6. Allocator (C++) - Wikipedia

    en.wikipedia.org/wiki/Allocator_(C++)

    Allocator (C++) In C++ computer programming, allocators are a component of the C++ Standard Library. The standard library provides several data structures, such as list and set, commonly referred to as containers. A common trait among these containers is their ability to change size during the execution of the program.

  7. Flexible array member - Wikipedia

    en.wikipedia.org/wiki/Flexible_array_member

    Flexible array member. C struct data types may end with a flexible array member [1] with no specified size: struct vectord { short len; // there must be at least one other data member double arr[]; // the flexible array member must be last // The compiler may reserve extra padding space here, like it can between struct members }; Typically ...

  8. Variable-length array - Wikipedia

    en.wikipedia.org/wiki/Variable-length_array

    Variable-length array. In computer programming, a variable-length array ( VLA ), also called variable-sized or runtime-sized, is an array data structure whose length is determined at runtime, instead of at compile time. [1] In the language C, the VLA is said to have a variably modified data type that depends on a value (see Dependent type ).

  9. x86 calling conventions - Wikipedia

    en.wikipedia.org/wiki/X86_calling_conventions

    The scheme allows for larger vector types (float, double, __m128, __m256) to be passed in registers as opposed to on the stack. [10] For IA-32 and x64 code, __vectorcall is similar to __fastcall and the original x64 calling conventions respectively, but extends them to support passing vector arguments using SIMD registers.
