libio defines four specialized classes for these cases:

ifstream
Methods for reading files.
ofstream
Methods for writing files.
istrstream
Methods for reading strings from memory.
ostrstream
Methods for writing strings in memory.

  • Files Reading and writing files.
  • Strings Reading and writing strings in memory.
