Exam 8: Advanced Collections

Normally you will want to use two integral values to reference individual elements in a two-dimensional array.If you use just one integral value,you get all of the values for that row.

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

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 heading for a method that could accept the two-dimensional array as an argument?

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.

For a declaration such as,int [ ,] anArray = new int [6,5],a total of 11 memory locations can be accessed using the identifier anArray.

A two dimensional array is accessed much like you access cells in a spreadsheet.

The ArrayList does not allow you to mix types.All elements must be of the same data type.

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 could be a method heading for a member method that returns a two-dimensional array?

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?

string sValue = "Life is about choices"; string [ ] sn = sValue.Split(' '); -After the above segment of code is executed,where is "choices" stored?

The string class stores an immutable series of characters--meaning once you assign a string reference a value,that referenced location's value cannot be modified.

The string method that retrieves part of a string from a string argument is ____.

One of the properties of the ArrayList class is ____. It Gets or sets the number of elements that the ArrayList can contain.

int[ ] [ ] anArray = new int[2] [ ]; anArray[0] = new int[ ] {100, 200}; anArray[1] = new int[ ] {11, 22, 37}; -The ____________ property can be used with multidimensional arrays to get the total number of elements in all dimensions.

The string is a reference type in C#.

Multi-dimensional array identifiers are normally defined using a plural noun.

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

The GetLength( )method can be called to return the number of rows or columns.

Which of the following would define a two dimensional structure to store temperature during three periods of a day for seven days?

Console.WriteLine(calories.GetUpperBound(0));returns the largest value in an array.
