CS 16 Plan for Today, 2/14/2018:

Review Exam 1 and PA3 solution

Streams and file I/O - basics[06-01.cpp]
	ifstream and ofstream objects [06-02.cpp]
	output formatting [06-06.cpp]

Also discussed: using objects (like ifstream)
	"dot operator" (e.g., object.function())
	<iomanip> formatting features like setw

And some Unix stuff (not required for CS 16):
	chmod to change file permissions, and ls -l
	cat command to show file contents
