Time Description 0:00:00 Array is a group of contiguous memory locations that all have the same name and type 0:01:57 Array program (Fig 8.2) 0:02:30 c.Length will give you the number of elements 0:03:20 Arrays must be declared with the keyword “new” because arrays are objects 0:03:40 Creates 5 integer elements, with indexes 0-4. 0:03:07 Program to show arrays passed to methods (Fig 8.13) 0:04:52 Var keyword 0:06:00 Arrays are passed to methods by reference 0:06:23 The individual array elements of primitive data types are passed by value. 0:07:39 Program for multidimensional arrays (Fig 8.19) 0:08:37 Jagged arrays 0:09:16 Multi-Dimensional Arrays are passed to methods by reference as well 0:09:45 Used nested for loops to access elements 0:09:55 b. GetLength() method 0:10:07 b.GetLength(0); returns the # of rows 0:10:18 b.GetLength(1); returns the # of columns 0:10:55 b.Length(); # of elements 0:11:10 Foreach statement 0:11:21 Chapter 8 16 26 27 28 Array program
