( 例如: cin.get() )，具体如下


int get();&

istream& get( char* pch, int nCount, char delim = '\n' );

istream& get( unsigned char* puch, int nCount, char delim = '\n' );

istream& get( signed char* psch, int nCount, char delim = '\n' );

istream& get( char& rch );

istream& get( unsigned char& ruch );

istream& get( signed char& rsch );

istream& get( streambuf& rsb, char delim = '\n' );

Parameters

pch, puch, psch

A pointer to a character array.

nCount

The maximum number of characters to store, including the terminating NULL.

delim

The delimiter character (defaults to newline).

rch, ruch, rsch

A reference to a character.

rsb

A reference to an object of a streambuf-derived class.

Remarks

These functions extract data from an input stream as follows:

Variation Description
get(); Extracts a single character from the stream and returns it.

get( char*, int, char ); Extracts characters from the stream until either delim is found, the limit nCount is reached, or the end of file is reached. The characters are stored in the array followed by a null terminator.

get( char& ); Extracts a single character from the stream and stores it as specified by the reference argument.

get( streambuf&, char ); Gets characters from the stream and stores them in a streambuf object until the delimiter is found or the end of the file is reached. The ios::failbit flag is set if the streambuf output operation fails.
