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 ...
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 ).
The Standard Template Library ( STL) is a software library originally designed by Alexander Stepanov for the C++ programming language that influenced many parts of the C++ Standard Library. It provides four components called algorithms, containers, functions, and iterators. [ 1]
An array is stored such that the position of each element can be computed from its index tuple by a mathematical formula. [ 1][ 2][ 3] The simplest type of data structure is a linear array, also called one-dimensional array. For example, an array of ten 32-bit (4-byte) integer variables, with indices 0 through 9, may be stored as ten words at ...
The variadic template feature of C++ was designed by Douglas Gregor and Jaakko Järvi [1] [2] and was later standardized in C++11. Prior to C++11, templates (classes and functions) could only take a fixed number of arguments, which had to be specified when a template was first declared. C++11 allows template definitions to take an arbitrary ...
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.
C++11 is a version of the ISO / IEC 14882 standard for the C++ programming language. C++11 replaced the prior version of the C++ standard, called C++03, [ 1] and was later replaced by C++14. The name follows the tradition of naming language versions by the publication year of the specification, though it was formerly named C++0x because it was ...
t. e. In the programming language C++, unordered associative containers are a group of class templates in the C++ Standard Library that implement hash table variants. Being templates, they can be used to store arbitrary elements, such as integers or custom classes. The following containers are defined in the current revision of the C++ standard ...
