get
Syntax:
#include <fstream> int get(); istream& get( char& ch ); istream& get( char* buffer, streamsize num ); istream& get( char* buffer, streamsize num, char delim ); istream& get( streambuf& buffer ); istream& get( streambuf& buffer, char delim );
The get() function is used with input streams, and either:
- reads a character and returns that value,
- reads a character and stores it as ch,
- reads characters into buffer until num - 1 characters have been read, or EOF or newline encountered,
- reads characters into buffer until num - 1 characters have been read, or EOF or the delim character encountered (delim is not read until next time),
- reads characters into buffer until a newline or EOF is encountered,
- or reads characters into buffer until a newline, EOF, or delim character is encountered (again, delim isn't read until the next get() ).
For example, the following code displays the contents of a file called temp.txt, character by character:
char ch; ifstream fin( "temp.txt" ); while( fin.get(ch) ) cout << ch; fin.close();
