14. Unformatted I/O Summary

Unformatted is typically viewed as

• low-level I/O

• highest efficiency

• individual character processing

Input normally finishes at end-of-file marker, EOF

Input proceeds regardless of multiple lines of text

Input has no automatic whitespace recognition

// Unformatted output
std::ostream std::cout;     // predefined

cout.put( c );              // single byte

cout.write( array, count ); // array of bytes



// Unformatted input
std::istream std::cin;      // predefined

c = cin.get( );             // single byte

cin.read( array, count );   // array of bytes
