C++_IO

• ifstream
  • ifstream i
  • peek()
    • i.peek();
    • Allows you to look at the character (byte) in the stream w/o removing it from the stream.
  • get()
    • Returns and consumes the next character in the stream
  • getline()
    • Two getline()s in C++
      • std::istream::getline()
        • cin.getline(char *, int)
        • String has to be big enough
      • std::getline(cin, std::string &)
        • uses a string object, which can grow
    • Both versions have an optional third parameter to specify a delimiter -- default is '\n'
  • operator>>()
    • Skips leading whitespace, then reads until next whitespace
• stringstream *
  • Similar to Java ArrayLists
  • Declare with templated (parameterized) type:
    • vector<int> v;
