Exam 8: Advanced Collections

Since the string data type is a reference type, you compare addresses as opposed to comparing contents or values when you use the equality operators with two string data items.

The method ____ of the ArrayList class returns an arraylist that is a subset of another arraylist.

C# has two types of string literals. Quoted string literals appear between double quotation marks (" ")  and verbatim string literal, which start with the at symbol (@).

The Queue class represents a Last In First Out (LIFO) collection of objects while the  Stack collection class represents a simple FIFO (First In First Out) collection.

To declare a three-dimensional array, three integral values are used. The first number specifies the number of ____________.

The ArrayList class requires you to add and remove elements to/from the structure using  Push( ) and Pop( ) methods.

The foreach loop structure cannot be used to iterate through a multi-dimensional array.

Console.Write("AnExample".PadLeft(20, "#") returns ____.

____ are types of data structures that consist of a sequence of data records such that in each record there is an additional field that contains a reference (i.e., a link) to the next record in the sequence.

As with the ArrayList class, in order to instantiate objects of many of the collection classes, you need to include a using ____________.

A Hashtable represents a collection of key/value pairs that are organized based on the hash code of the key.

double [  ,  ] price = new double [2 , 5] {{1.1, 1.2, 1.3, 1.5, 1.4}{2.1, 2.2, 2.3, 2.5, 2.4}}; Looking above, the value of price.Length is 10.

In C#, a two-dimensional array is usually visualized as a table divided into columns and rows where data is stored in contiguous memory locations by column.

In order to determine the position of one or more characters inside a string argument, use the ____ method of the string class.

If an array named num is dimensioned to hold 10 values in 5 rows and 2 columns, how would you store 50 in the first physical row and first physical column?

With a two-dimensional array, GetLength(0) returns the number of rows and GetLength(1) returns the number of columns in the array.

The Rank property is used with array collections to return the number of dimensions.

The major requirement of dealing with multi-dimensional arrays is the fact that all data values placed in an array must be of the same base type.

The ____________ method is used with the ArrayList class to push items on the list.

Which of the following returns the number of columns in a two-dimensional array?
