template< class T, class Container > void swap( stack<T,Container>& lhs, stack<T,Container>& rhs ); Specializes the std::swap algorithm for std::stack. Swaps the contents of lhs and rhs. Calls lhs.swap(rhs). Parameters lhs, rhs - containers whose contents to swap Return value (none). Complexity Same as swapping the underlying container. Exceptions noexcept specification: noexcept(noexcept(lhs.swap(rhs))) (since C++17) See

Defined in header <cwchar> int fwide( std::FILE* stream, int mode ); If mode > 0, attempts to make stream wide-oriented. If mode < 0, attempts to make stream byte-oriented. If mode==0, only queries the current orientation of the stream. If the orientation of the stream has already been decided (by executing output or by an earlier call to fwide), this function does nothing. Parameters stream - pointer to the C I/O stream to modify or query mode - integer

float max_load_factor() const; (1) (since C++11) void max_load_factor( float ml ); (2) (since C++11) Manages the maximum load factor (number of elements per bucket). The container automatically increases the number of buckets if the load factor exceeds this threshold. 1) Returns current maximum load factor. 2) Sets the maximum load factor to ml. Parameters ml - new maximum load factor setting Return value 1) current maximum load factor. 2) none. Complexity Constan

std::vector<double> probabilities() const; (since C++11) Obtains a std::vector<double> containing the individual probabilities of each integer that is generated by this distribution. Parameters (none). Return value An object of type std::vector<double> Example #include <iostream> #include <vector> #include <random> int main() { std::discrete_distribution<> d({40, 10, 10, 40}); std::vector<double> p = d.probabilities();

pointer release(); (since C++11) Releases the ownership of the managed object if any. get() returns nullptr after the call. Parameters (none). Return value Pointer to the managed object or nullptr if there was no managed object, i.e. the value which would be returned by get() before the call. Exceptions noexcept specification: noexcept Example #include <memory> #include <iostream> #include <cassert> struct Foo { Foo() { std::cout << "Foo\n";

Defined in header <utility> template< class T, T... Ints > class integer_sequence; (since C++14) The class template std::integer_sequence represents a compile-time sequence of integers. When used as an argument to a function template, the parameter pack Ints can be deduced and used in pack expansion. Template parameters T - an integer type to use for the elements of the sequence ...Ints - a non-type parameter pack representing the sequence Member ty

template< class Iterator1, class Iterator2 > auto operator-( const move_iterator<Iterator1>& lhs, const move_iterator<Iterator2>& rhs ) -> decltype(lhs.base() - rhs.base()); (since C++11) Returns the distance between two iterator adaptors. Parameters lhs, rhs - iterator adaptors to compute the difference of Return value lhs.base() - rhs.base(). Example

Defined in header <codecvt> template< class Elem, unsigned long Maxcode = 0x10ffff, std::codecvt_mode Mode = (std::codecvt_mode)0 > class codecvt_utf16 : public std::codecvt<Elem, char, std::mbstate_t>;; std::codecvt_utf16 is a std::codecvt facet which encapsulates conversion between a UTF-16 encoded byte string and UCS2 or UCS4 character string (depending on the type of Elem). This codecvt facet can be used to read and write UTF-16 files in
