Object-oriented Programming

Notes 3. How does that funky while (std::cin >> foo) syntax work?
4. Why does my input seem to process past the end of file?
5. Why we should end the output lines with std::endl or ‘\n’?
6. Why shouldn’t we always use a printOn() method rather than a friend function?

7. How can we provide printing for an entire hierarchy of classes?
8. How can we open a stream in binary mode?
9. How can we “reopen” std::cin and std::cout in binary mode?
10. How can we write/read objects of my class to/from a data file?
