Question 1

An array's______ determines the number of elements in the array.&#10;A) type&#10;B) length&#10;C) height&#10;D) width&#10;E) Both a and b.

Accepted Answer

The length of an array determines the number of elements it can hold. This is a fundamental property of arrays in programming, where the length specifies the total count of indices or slots available for storing values.

Question 2

A Combobox's_________ property, when set to , specifies that the Combobox values cannot be edited by the user and that the Combobox will use a drop-down list to display its values.&#10;A) DropDown, List&#10;B) Style, DropDown&#10;C) DropDownStyle, List&#10;D) DropDownStyle, DropDownList&#10;E) Style, DropDownList

Accepted Answer

The correct property is `DropDownStyle`, and setting it to `DropDownList` ensures that the ComboBox values cannot be edited by the user and that the ComboBox will display its values using a drop-down list.

Question 3

A(n)_____ groups together and organizes related data.&#10;A) procedure&#10;B) data structure&#10;C) class&#10;D) array&#10;E) Both b and d.

Accepted Answer

Data structures (B) and arrays (D) both group together and organize related data. Data structures are general concepts that include arrays, linked lists, trees, and more, designed to organize and manage data efficiently. Arrays are a type of data structure specifically for storing elements of the same type in an indexed way.

Question 4

The ComboBox's ______property, when set to______ , sorts the items in the ComboBox alphabetically.&#10;A) Sorted, true&#10;B) UnSorted, false&#10;C) Alphabetize, true&#10;D) Sort, true&#10;E) None of the above.

Accepted Answer

The ComboBox's Sorted property, when set to true, sorts the items in the ComboBox alphabetically.

Question 5

When the Remove method is called on a string,____ .&#10;A) the first argument passed to the method is an index&#10;B) the second argument passed to the method specifies the number of characters to delete&#10;C) the method operates on a copy of the string&#10;D) the method returns a string&#10;E) All of the above.

Accepted Answer

The Remove method in C# strings takes an index as the first argument, specifying where to start removing characters. The second argument, if provided, specifies the number of characters to remove. Since strings in C# are immutable, the method operates on a copy of the string and returns a new string with the specified characters removed, making all of the statements correct.

Question 6

A(n) ______is an array name followed by an index enclosed in parentheses.&#10;A) container&#10;B) subscript&#10;C) indexed array name&#10;D) position&#10;E) None of the above.

Accepted Answer

An indexed array name consists of the array name followed by an index enclosed in parentheses, which is used to access specific elements within the array.

Question 7

The Sort method, when called_____ , sorts the array alphabetically.&#10;A) from class Sorter&#10;B) on a string array only&#10;C) from class Array&#10;D) from class DataStructure and passed a string array&#10;E) None of the above.

Accepted Answer

The Sort method is a method of the Array class. It sorts the elements of an array in ascending order.

Question 8

Attempting to access an element in an array by using an index outside the array's bounds______ .&#10;A) is a syntax error&#10;B) is an array-time error&#10;C) is a run-time error&#10;D) returns the data-type's default value&#10;E) returns the value of the last value in the array

Accepted Answer

Accessing an element outside the bounds of an array does not cause a syntax error or return a default value; instead, it typically results in a run-time error because the access is attempted during the execution of the program, and the program cannot safely access memory locations outside the defined array bounds.
