  2. C++ Standard Library - Wikipedia

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

    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.

  3. Standard Template Library - Wikipedia

    en.wikipedia.org/wiki/Standard_Template_Library

    similar to a set, multiset, map, or multimap, respectively, but implemented using a hash table; keys are not ordered, but a hash function must exist for the key type. 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 ...

  4. Unordered associative containers (C++) - Wikipedia

    en.wikipedia.org/wiki/Unordered_associative...

    The containers are defined in headers named after the names of the containers, e.g., unordered_set is defined in header <unordered_set>. All containers satisfy the requirements of the Container concept , which means they have begin() , end() , size() , max_size() , empty() , and swap() methods.

  5. Associative containers (C++) - Wikipedia

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

    When program is executed, six elements are inserted using the insert() function, then the first element is deleted using erase() function and the size of the map is outputted. Next, the user is prompted for a key to search for in the map. Using the iterator created earlier, the find() function searches for an element with the given key. If it ...

  6. setcontext - Wikipedia

    en.wikipedia.org/wiki/Setcontext

    uc_sigmask is used to store the set of signals blocked in the context, and uc_stack is the stack used by the context. uc_mcontext stores execution state, including all registers and CPU flags, the instruction pointer, and the stack pointer; mcontext_t is an opaque type. The functions are: int setcontext (const ucontext_t * ucp)

  7. Functional (C++) - Wikipedia

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

    The C++ Standard Library provides base classes unary_function and binary_function to simplify the definition of adaptable unary functions and adaptable binary functions. Adaptable function objects are important, because they can be used by function object adaptors: function objects that transform or manipulate other function objects.

  8. C standard library - Wikipedia

    en.wikipedia.org/wiki/C_standard_library

    C standard library functions are exported from the C++ standard library in two ways. For backwards-/cross-compatibility to C and pre-Standard C++, functions can be accessed in the global namespace (::), after #include ing the C standard header name as in C. [42] Thus, the C++98 program

  9. Set (abstract data type) - Wikipedia

    en.wikipedia.org/wiki/Set_(abstract_data_type)

    The set of all bags over type T is given by the expression bag T. If by multiset one considers equal items identical and simply counts them, then a multiset can be interpreted as a function from the input domain to the non-negative integers (natural numbers), generalizing the identification of a set with its indicator function. In some cases a ...
