Defined in header <cmath> float frexp( float arg, int* exp ); (1) double frexp( double arg, int* exp ); (2) long double frexp( long double arg, int* exp ); (3) double frexp( Integral arg, int* exp ); (4) (since C++11) 1-3) Decomposes given floating point value arg into a normalized fraction and an integral power of two. 4) A set of overloads or a function template accepting an argument of any integral type. Equivalent to (2) (the argumen

bool bad() const; Returns true if non-recoverable error has occurred on the associated stream. Specifically, returns true if badbit is set in rdstate(). See ios_base::iostate for the list of conditions that set badbit. Parameters (none). Return value true if a non-recoverable error has occurred, false otherwise. Example #include <iostream> #include <fstream> #include <cstdlib> int main() { std::ifstream file("test.txt"); if(!file) // operator! is us

duration& operator++(); (1) duration operator++(int); (2) duration& operator--(); (3) duration operator--(int); (4) Increments or decrements the number of ticks for this duration. If rep_ is a member variable holding the number of ticks in a duration object, 1) Equivalent to ++rep_; return *this; 2) Equivalent to return duration(rep_++) 3) Equivalent to --rep_; return *this; 4) Equivalent to return duration(rep_--); Parameters (none). Return value

RealType a() const; (1) (since C++11) RealType b() const; (2) (since C++11) Returns the distribution parameters with which the distribution was constructed. 1) Returns the a parameter. It specifies the location of the peak and is also called location parameter. The default value is 0.0. 2) Returns the b parameter. It represents the half-width at half-maximum (HWHM) and is also called scale parameter. The default value is 1.0. Parameters (none). Return value 1) The value o

template< class T > /*unspecified1*/ begin( valarray<T>& v ); (1) (since C++11) template< class T > /*unspecified2*/ begin( const valarray<T>& v ); (2) (since C++11) The overload of std::begin for valarray returns an iterator of unspecified type referring to the first element in the numeric array. 1) The return type meets the requirements of mutable RandomAccessIterator. 2) The return type meets the requirements of constant RandomAccessIterator.

Defined in header <cwchar> wchar_t *wcscat( wchar_t *dest, const wchar_t *src ); Appends a copy of the wide string pointed to by src to the end of the wide string pointed to by dest. The wide character src[0] replaces the null terminator at the end of dest. The resulting wide string is null-terminated. The behavior is undefined if the destination array is not large enough for the contents of both str and dest and the terminating null wide character. The behavior is undefine
