Exam 7: Arrays and Lists

You can use subscript notation to access items in a List, just as you can with an array.

When you create a numeric array in C#, what default value is assigned to its elements?

The ____________ algorithm is much more efficient than a sequential search when the data set is very large.

When working with an array, you cannot use a subscript that is less than 0 or greater than the array size minus 1.

Each item stored in a List has a corresponding index.

Various techniques known as ____________ have been developed to locate a specific item in a larger collection of data, such as an array.

In C#, all arrays have a(n) ____________ that equals the number of elements in the array.

Look at the following code sample: const int ROWS = 8; Const int COLS = 2; Int[,] table = new int[ROWS, COLS]; Which one of the following statements stores the value 25 in the element located at the first row and second column of the table array?

With what value should the accumulator variable be initialized to calculate the total of all values in a numeric array?

It is preferred practice to use a(n) ____________ as an array's size declarator.

The first step in calculating the average of all values in a numeric array is to get the total of the values, and the second step is to multiply the total by the number of elements in the array.

To access a single element in a two-dimensional array, you must use two subscripts.

Which one of the following statements is not a valid array declaration?

The primary advantage of the binary search algorithm is simplicity, but its primary disadvantage, however, is inefficiency.

Which one of the following declaration statements is not a value type?

You can use the == operator to compare two array reference variables and determine whether the array contents are equal.

The .NET Framework provides a class named Container, which can be used for storing and retrieving items.

Arrays are always passed by value when passed as method arguments.

The ____________ uses a loop to step through the elements in an an array one by one, from the first to the last.

To sum all the elements of a two-dimensional array, you can use a pair of nested if statements to add the contents of each element to the accumulator.
