Question 1

An element in an array is 3 bytes long and there are 10 elements in the array.How big is the array?
A) 30 bytes
B) 10 bytes
C) 3 bytes
D) Not enough information to determine

Accepted Answer

To find the size of the array, we need to multiply the length of each element by the number of elements. Therefore, 3 bytes x 10 elements = 30 bytes.

Question 2

When declaring an array,depending on the syntax rules of the programming language you use,you place the subscript within parentheses or ____ following the group name.
A) asterisks
B) slashes
C) curly brackets
D) square brackets

Accepted Answer

The subscript is placed within square brackets following the group name.

Question 3

A ____ search starts looking in the middle of a sorted list,and then determines whether it should continue higher or lower.
A) linear
B) quick
C) graphic
D) binary

Accepted Answer

A binary search is designed to quickly find a specific item in a large list of items by dividing the list in half repeatedly until the item is found. It starts looking in the middle of a sorted list, and then determines whether it should continue higher or lower. This process continues until either the item is found or it is determined that the item is not in the list. Therefore, binary search is the best choice for this situation.

Question 4

When you search through a list from one end to the other,you are performing a ____ search.
A) linear
B) binary
C) quick
D) Google

Accepted Answer

A linear search is performed by searching through a list from one end to the other, comparing each element until a match is found or the end of the list is reached. Binary search involves dividing a sorted array into two halves repeatedly until the target element is found, and quick search is an algorithm used to sort a list. Google is a search engine, not a search algorithm.

Question 5

In Java,C++,and C#,the for loop looks like the following: A) for(dep = 0; dep++; dep < SIZE) B) for(dep > SIZE; dep = 0; dep++) C) for(dep = 0; dep < SIZE; dep++) D) for(dep = SIZE,dep > 0,dep++)

Accepted Answer

The correct syntax of the for loop in these programming languages is to initialize the counter variable(dep) to 0, provide a condition to execute the loop(dep < SIZE), and define the increment or decrement(dep++) to the counter variable. option A increments dep first before checking its condition, and option B initializes dep to a value greater than SIZE, which makes the condition false in the first iteration itself. Option D starts the loop backward and keeps looping, violating the purpose of the loop to control the flow of a statement.

Question 6

Learning to use arrays correctly can make many programming tasks far more ____ and professional.
A) confusing
B) efficient
C) slick
D) literal

Accepted Answer

Arrays can help organize and manipulate large sets of data more efficiently, making code more professional and easier to read.

Question 7

The ____ is a particularly convenient tool when working with arrays because you frequently need to process every element of an array from beginning to end.
A) binary search
B) range check
C) for loop
D) parallel array

Accepted Answer

The for loop is designed to iterate over a range of values, typically used to process every element of an array in turn. This makes it a very convenient tool for working with arrays.

Question 8

Leaving a loop as soon as a match is found improves the program's ____.
A) indirect relationships
B) logic
C) simplicity
D) efficiency

Accepted Answer

Leaving a loop as soon as a match is found reduces the number of iterations the program has to go through, improving its efficiency.

Question 9

Frequently,a flag holds a ____ value.
A) subscript
B) true or false
C) string
D) junk

Accepted Answer

In programming, a flag variable is used to store a boolean (true or false) value that represents the state of a condition or situation. Therefore, the best choice is B, true or false.

Question 10

The relationship between an item's number and its price is a(n)____ relationship.
A) direct
B) indirect
C) hidden
D) clear

Accepted Answer

The answer of The relationship between an item's number and...

Question 11

Besides making your code easier to modify,using a ____ makes the code easier to understand.
A) constant
B) named constant
C) named declaration
D) named variable

Accepted Answer

A named constant provides a descriptive name for a value that does not change during program execution. This makes the code easier to understand as it allows the reader to easily identify the value and its purpose without having to search through the code to find it.

Question 12

When you use parallel arrays,a ____ relates the arrays.
A) link
B) flag
C) subscript
D) script

Accepted Answer

A subscript relates the arrays in parallel arrays, as it is used to access corresponding elements in each array.

Question 13

When you use parallel arrays,two or more arrays contain ____ data.
A) connected
B) equivalent
C) identical
D) related

Accepted Answer

Parallel arrays contain related data, meaning each element in one array is related to the element in the corresponding position in the other array(s). They are not necessarily identical, equivalent or always connected.

Question 14

A ____ is a variable that you set to indicate whether some event has occurred.
A) handler
B) rudder
C) flag
D) bug

Accepted Answer

A flag is a common programming term used to represent a variable that is set to indicate whether a particular event has occurred. The value of the flag can then be checked and used to trigger other actions or decisions in the program. A handler is a term used to refer to a function or piece of code that is called in response to a particular event or trigger. A rudder is a mechanical device used to steer a ship or other vehicle. A bug is an error or flaw in a program that causes unexpected or unintended behavior.

Question 15

Most programming languages use a statement similar to the following to declare a three-element array and assign values to it: ____
A) {20,30,40} = num someVals[3]
B) num someVals[3] = {someVals}
C) num someVals[] = 20,30,40
D) num someVals[3] = 20,30,40

Accepted Answer

In programming languages like Java or C++, the syntax to declare and assign values to a three-element array is to use the square brackets [] to define the size of the array and then assign values within curly braces {}. For example, "num someVals[3] = {20, 30, 40}." This syntax declares an array of type "num" (which is shorthand for number) called "someVals" with a size of three, and assigns the values 20, 30, and 40 to the array elements.

Question 16

When working with arrays,you can use ____ in two ways: to hold an array's size and as the array values.
A) structures
B) literals
C) constants
D) strings

Accepted Answer

Constants can be used to hold the size of an array and its values. Once a constant is defined, it cannot be modified. This ensures that the size of the array doesn't change accidentally and that the array values remain constant throughout the program. Using structures or strings would not be suitable for this purpose, and literals (although they can be used as array values) cannot be used to hold the array size.

Question 17

The true benefit of an array lies in your ability to use a(n)____ as a subscript to the array.
A) variable
B) table
C) operator
D) field

Accepted Answer

Using a variable as a subscript allows for dynamic access and modification of array elements, making the code more flexible and efficient.

Question 18

In ____ arrays,each element in one array is associated with the element in the same relative position in the other array.
A) parallel
B) related
C) grouped
D) combined

Accepted Answer

Parallel arrays are two or more arrays where the elements in the same index positions are related to each other. This means that each element in one array is associated with the element in the same relative position in the other array. This makes it easy to work with related data in a program, as the corresponding elements of the arrays can be accessed and processed at the same time. Option B, related arrays, is not a commonly used term in computer science, and options C and D are not accurate descriptions of parallel arrays.

Question 19

When you have a six element array and use subscript 6,your subscript is said to be out of ____.
A) bounds
B) scope
C) range
D) array

Accepted Answer

Subscript being out of bounds means that it is referring to an element that does not exist within the array.

Question 20

What is TRUE about the following array? num someVals[5] = 1,3,5,7,9
A) someVals[1] has the value of 1
B) someVals[1] has the value of 3
C) There are 6 elements in this array.
D) someVals[3] has the value of 3

Accepted Answer

The syntax for initializing an array is incorrect. However, assuming the correct syntax should be: 
int someVals[5] = {1,3,5,7,9};
Then, someVals[1] would have the value of 3. Option A is incorrect since someVals[1] would actually hold the value of 3. Option C is incorrect because there are only 5 elements in this array. Option D is incorrect because someVals[3] would hold the value of 7.
