可以用 istream::get()( 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 (more...)
