Defined in header <random> template< class RealType = double > class fisher_f_distribution; (since C++11) Produces random numbers according to the f-distribution: p(x;m,n) = Γ((m+n)/2) Γ(m/2) Γ(n/2) (m/n)m/2 x(m/2)-1 (1+ mxn )-(m+n)/2 m and n are the degrees of freedom. std::fisher_f_distribution satisfies all requirements of RandomNumberDistribution. Template parameters RealType - The result type generated by the generator. The effect is undefined i

explicit fisher_f_distribution( RealType m = 1.0, RealType n = 1.0 ); (1) (since C++11) explicit fisher_f_distribution( const param_type& params ); (2) (since C++11) Constructs a new distribution object. The first version uses m and n as the distribution parameters, the second version uses params as the distribution parameters. Parameters m - the m distribution parameter (degrees of freedom) n - the n distribution parameter (degrees of freedom) params - the

Defined in header <cwchar> wchar_t* fgetws( wchar_t* str, int count, std::FILE* stream ); Reads at most count - 1 wide characters from the given file stream and stores them in str. The produced wide string is always null-terminated. Parsing stops if end-of-file occurs or a newline wide character is found, in which case str will contain that wide newline character. Parameters str - wide string to read the characters to count - the length of str stream - f

Defined in header <cstdio> char* fgets( char* str, int count, std::FILE* stream ); Reads at most count - 1 characters from the given file stream and stores them in str. The produced character string is always null-terminated. Parsing stops if end-of-file occurs or a newline character is found, in which case str will contain that newline character. Parameters str - string to read the characters to count - the length of str stream - file stream to read the

Defined in header <algorithm> template< class OutputIt, class Size, class T > void fill_n( OutputIt first, Size count, const T& value ); (until C++11) template< class OutputIt, class Size, class T > OutputIt fill_n( OutputIt first, Size count, const T& value ); (since C++11) Assigns the given value to the first count elements in the range beginning at first if count > 0. Does nothing otherwise. Parameters first - the beginning of the ran

Defined in header <algorithm> template< class ForwardIt, class T > void fill( ForwardIt first, ForwardIt last, const T& value ); Assigns the given value to the elements in the range [first, last). Parameters first, last - the range of elements to modify value - the value to be assigned Type requirements - ForwardIt must meet the requirements of ForwardIterator. Return value (none). Complexity Exactly last - first assignments. Possible

Defined in header <cwchar> wint_t fgetwc( std::FILE* stream ); wint_t getwc( std::FILE* stream ); Reads the next wide character from the given input stream. getwc() may be implemented as a macro and may evaluate stream more than once. Parameters stream - to read the wide character from Return value The next wide character from the stream or WEOF if an error has occurred or the end of file has been reached. If an encoding error occurred, errno is set to E

Defined in header <cstdio> int fgetc( std::FILE* stream ); int getc( std::FILE* stream ); Reads the next character from the given input stream. Parameters stream - to read the character from Return value The obtained character on success or EOF on failure. If the failure has been caused by end of file condition, additionally sets the eof indicator (see std::feof()) on stream. If the failure has been caused by some other error, sets the error indicator (see std

Defined in header <cstdio> int fgetpos( std::FILE* stream, std::fpos_t* pos ); Obtains the file position indicator and the current parse state (if any) for the file stream stream and stores them in the object pointed to by pos. The value stored is only meaningful as the input to std::fsetpos. Parameters stream - file stream to examine pos - pointer to a fpos_t object to store the file position indicator to Return value ​0​ upon success, nonzero value oth
