CS 16 Plan for Today, 2/26/2018:

Review PA4 solution

More 1D array topics:
	Using arrays to count [rolldie.cpp]
	Partially filled arrays [07-09.cpp]
	Searching an array [07-10.cpp]
	Sorting an array [07-12.cpp, 07-13.cpp]

Multidimensional arrays - think nested loops
	[07-14.cpp, and Displays 7.15-16]

C-style string basics (start of Chapter 8)
	char s[4] = "abc";  // s[3] is ‘\0’
	char t[] = "defg";  // t size is 5
	char x[] = "hi", y[] = "hi"; // x != y
	    // so instead check strcmp(x,y) == 0
	More <cstring> functions [Display 8.1]

Command line arguments [args.cpp from PA5]
