Exam 8: Advanced Collections

int [ ,,] anArray = new [3,2,7] allows ____ elements to be stored.

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

int [ , ] score = {{88, 66, 76, 92, 95} {67, 88, 45, 99, 80}}; int total = 0; foreach (int val in score) total += val; -Which of the following is a valid example of calling a method and sending it a two-dimensional array argument?

string sValue = "Life is about choices"; string [ ] sn = sValue.Split(' '); -Which method in the string class might be useful to create a table with values number aligned?

Console.Write("anExample".IndexOf("a"));returns ____.

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

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

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}}; -With the declaration above,price[1] refers to 1.2.

With C#,you are limited to 10 dimensions for multi-dimensional arrays.

int[ ] [ ] anArray = new int[2] [ ]; anArray[0] = new int[ ] {100, 200}; anArray[1] = new int[ ] {11, 22, 37}; -The above segment of code ____.

C# uses a row major format for accessing arrays,which means that the elements are printed in rows.Every entry in the first column is printed before moving to the second column.

Strings are considered ____________ because once you give a string a value;it cannot be modified.Methods that seem to be modifying a string are actually returning a new string containing the modification.

With a two dimensional array,when the number of columns in the rows differs,a jagged array can be created.

____ 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.

int [ , ] score = {{88, 66, 76, 92, 95} {67, 88, 45, 99, 80}}; int total = 0; foreach (int val in score) total += val; -BinarySearch( )is ____.

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

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.

int[ ] [ ] anArray = new int[2] [ ]; anArray[0] = new int[ ] {100, 200}; anArray[1] = new int[ ] {11, 22, 37}; -For a two-dimensional array,values are stored ____________ using a row major format.

int [ , ] score = {{88, 66, 76, 92, 95} {67, 88, 45, 99, 80}}; int total = 0; foreach (int val in score) total += val; -Using the code shown above,what is added to total during the first iteration?

int[ ] [ ] anArray = new int[2] [ ]; anArray[0] = new int[ ] {100, 200}; anArray[1] = new int[ ] {11, 22, 37}; -The property ____________ returns the number of dimensions of the array.
