Exam 7: Arrays and Lists

The only requirement for using a binary search is that the values in the array must be sorted in ascending or descending order.

An exception will occur if a List index is less than 0 or greater than the List's Count property minus 1.

Because array subscripts start at 1 rather than 0, you are not as likely to perform an off-by-one error.

Unlike a one-dimensional array, you cannot provide an initialization list for a two-dimensional array.

A(n) ____________ is similar to an array, but it can expand at runtime.

Arrays are reference type objects.

The sequential search algorithm is the simplest of all array searching algorithms.

When working with an array, it is important that you do not use a(n)____________.

If you want to make a separate copy of an array, you must create the second array in memory and then copy the individual elements of the first array to the second. This is known as a deep copy.

You can use the ____________ to take out an item at a specific index in a List.

To access an item that is stored in a particular row and column in a jagged array, you enclose the row and column subscripts in their own pairs of brackets..

To compare the contents of two arrays, you must compare each of the ____________ in the two arrays.

You can create an array to hold any single type of value.

____________ is a process that runs automatically in the background from time to time, removing all unreferenced objects from memory.

Creating a reference type object typically requires the following two steps, which can optionally be coded in a single program statement: 1. Declare a reference variable. 2. Create an object and associate it with the reference variable.

You cannot reassign an array reference variable to a different array.

When you create an array, you can optionally initialize it with a collection of values called a(n) ____________.

Look at the following code sample: int[,] values = { { 1, 2, 3, 4 }, { 5, 6, 7, 8 } }; What is the value stored in values[1, 2]?

If you know the value of the item you want to take out from a List object, but you do not know the item's index, you can use the ____________.
