Deck 2: First You Need to Plan the Party Problem-Solving Process

Question 1

Most algorithms begin with an instruction that enters the input items into the computer.

Answer 1

True

Question 2

Most algorithms end with an instruction to print, display, or store the output items.

Answer 2

True

Question 3

Analyzing real-world problems is generally as easy as analyzing the problems found in a textbook.

Answer 3

False

Question 4

Not all algorithms require a processing item.

Question 5

Before you begin the desk-check, you first choose a set of sample data for the input values, which you then use to manually compute the expected output values.

Question 6

When determining the output, it helps to think about the information that you would need to solve the problem manually.

Question 7

Unlike a flowchart, pseudocode uses standardized symbols to visually depict an algorithm.

Question 8

You can draw the flowchart symbols by hand; or, you can use the drawing or shapes feature in a word processor.

Question 9

Desk-checking is also called pencil-tracing, because the programmer uses a pencil and paper to follow each of the algorithm's instructions.

Question 10

When planning an algorithm, you need to create both a flowchart and pseudocode.

Question 11

The final step that programmers follow when they solve problems is to rigorously test the program using the computer.

Question 12

Display, print, and store refer to a file on disk, the printer, and the computer screen, respectively.

Question 13

The two most important components of any problem are the problem's output and its input.

Question 14

The input typically is stated as nouns and adjectives in the problem specification.

Question 15

If you are having trouble analyzing a problem, try reading the problem specification several times, as it is easy to miss information during the first reading.

Question 16

For simple algorithms, flowcharts work just fine.

Question 17

The first step that programmers follow when they solve problems is to plan the algorithm.

Question 18

Pseudocode is standardized.

Question 19

When analyzing a problem, you always search first for the input, and then for the output.

Question 20

To avoid confusion, it is important that the algorithm is consistent when referring to the input and output items.

Question 21

What the user wants to see printed on paper, displayed on the screen, or stored in a file is typically stated as ____ and adjectives in the problem specification.

A) adverbs
C) nouns
B) commands
D) verbs

Question 22

A helpful way to identify the ____ is to search the problem specification for what the user wants to see printed on paper, displayed on the screen, or stored in a file.

A) output
C) yield

A) yield
C) contribution
B) output
D) input

Question 25

A) yield
C) symbol
B) output
D) input

Question 26

The oval symbol in a flowchart is called the ____ symbol.

A) start/stop
C) process
B) input/output
D) flow

Question 27

A helpful way to identify the ____ is to search the problem specification for what information the computer will need to know to print, display, or store the output items.

A) output
C) yield
B) symbols
D) input

Question 28

The rectangle in a flowchart is called the ____ symbol and is used to represent tasks such as calculations.

A) start/stop
C) process
B) input/output
D) flow

Question 29

The parallelogram symbol in a flowchart is called a(n) ____ symbol.

A) start/stop
C) process
B) input/output
D) flow

Question 30

Programmers use the pseudocode as a guide when coding the algorithm, which is the ____ step in the problem-solving process.

A) second
C) fourth
B) third
D) fifth

Question 31

Symbols are connected with lines, called ____.

A) chartlines
C) leaders
B) flowlines
D) trackers

Question 32

It is helpful to use a desk-check table when desk-checking an algorithm.

Question 33

The ____ is the item or items needed to achieve the goal.

A) yield
C) contribution
B) output
D) input

Question 34

The ____ step is the most difficult of the problem-solving steps, and it requires a lot of time, patience, and effort.

A) planning
C) analysis
B) desk-check
D) testing

Question 35

The second step in the problem-solving process is to plan the ____, which is the set of instructions that, when followed, will transform the problem's input into its output.

A) program
C) instructions
B) algorithm
D) statements

Question 36

Programmers use ____ to help them while they are planning an algorithm.

A) pseudocode
C) templates

A) adjectives
C) nouns
B) verbs
D) adverbs

Question 38

Besides using pseudocode, programmers also use ____ when planning algorithms.

A) pseudocharts
C) flowcharts
B) templates
D) coding sheets

Question 39

You should test an algorithm with invalid data because users sometimes make mistakes when entering data.

Question 41

____ data is data that the algorithm is not expecting the user to enter.

A) Invalid
C) Unchecked
B) Checked
