Defined in header <algorithm> template< class BidirIt, class UnaryPredicate > BidirIt stable_partition( BidirIt first, BidirIt last, UnaryPredicate p ); Reorders the elements in the range [first, last) in such a way that all elements for which the predicate p returns true precede the elements for which predicate p returns false. Relative order of the elements is preserved. Parameters first, last - the range of elements to reorder p - unary predicate whic

This header was originally in the C standard library as <iso646.h>. Compatibility header, in C defines alternative operator representations which are keywords in C++. This means that in a conforming implementation this header is empty. It may still be required in order to have the alternative operator representations in old or non-conformant compilers.

template< class... Args > std::pair<iterator,bool> emplace( Args&&... args ); (since C++11) Inserts a new element into the container by constructing it in-place with the given args if there is no element with the key in the container. Careful use of emplace allows the new element to be constructed while avoiding unnecessary copy or move operations. The constructor of the new element (i.e. std::pair<const Key, T>) is called with exactly the same arguments as sup

Defined in header <cstdio> int setvbuf( std::FILE* stream, char* buffer, int mode, std::size_t size ); Changes the the buffering mode of the given file stream stream as indicated by the argument mode. In addition, If if buffer is a null pointer, resizes of the internal buffer to size. If buffer is not a null pointer, instructs the stream to use the user-provided buffer of size size beginning at buffer. The stream must be closed (with fclose) before the lifetime of the ar

Defined in header <sstream> template< class CharT, class Traits = std::char_traits<CharT> > class basic_ostringstream; (until C++11) template< class CharT, class Traits = std::char_traits<CharT>, class Allocator = std::allocator<CharT> > class basic_ostringstream; (since C++11) The class template std::basic_ostringstream implements output operations on memory (std::basic_string) based streams. It essentially wraps

static constexpr T lowest() (since C++11) Returns the lowest finite value representable by the numeric type T, that is, a finite value x such that there is no other finite value y where y < x. This is different from std::numeric_limits<T>::min() for floating-point types. Only meaningful for bounded types. Return value T std::numeric_limits<T>::lowest() /* non-specialized */ T(); bool false char CHAR_MIN signed char SCHAR_MIN unsigned char ​0​ w

Defined in header <cmath> float floor( float arg ); (1) double floor( double arg ); (2) long double floor( long double arg ); (3) double floor( Integral arg ); (4) (since C++11) 1-3) Computes the largest integer value not greater than arg. 4) A set of overloads or a function template accepting an argument of any integral type. Equivalent to 2) (the argument is cast to double). Parameters arg - floating point value Return val

Defined in header <codecvt> template< class Elem, unsigned long Maxcode = 0x10ffff, std::codecvt_mode Mode = (std::codecvt_mode)0 > class codecvt_utf8 : public std::codecvt<Elem, char, std::mbstate_t>; std::codecvt_utf8 is a std::codecvt facet which encapsulates conversion between a UTF-8 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-8 files, both text and

Defined in header <locale> template< class CharT, class OutputIt = std::ostreambuf_iterator<CharT> > class time_put; Class template std::time_put encapsulates date and time formatting rules. The I/O manipulator std::put_time uses the std::time_put facet of the I/O stream's locale to generate text representation of an std::tm object. Inheritance diagram. Type requirements - OutputIt must meet the requirements of OutputIterator. Specializ

void remove( const T& value ); (since C++11) template< class UnaryPredicate > void remove_if( UnaryPredicate p ); (since C++11) Removes all elements satisfying specific criteria. The first version removes all elements that are equal to value, the second version removes all elements for which predicate p returns true. Parameters value - value of the elements to remove p - unary predicate which returns ​true if the element should be removed. The signature of
