• Data ``run'' through streams
• Stream types: input, output, input/output, standard, file, string, user-defined
  outputStreamName « varName or literal ... ; std::cout « "i = " « i « std::endl;
  inputStreamName » varName ; std::cin » i;
  

  stringstream buffer;
  char myFileName[] = "config.txt";
  ifstream inputFileStream(myFileName);
  char nextChar;
  while(inputFileStream && !inputFileStream.eof()) {
  inputFileStream.get(nextChar);
  buffer « nextChar;
  }
  cout « buffer.str();
