Question 1

The purpose of a test or decision in a looping structure is to tell when the loop should end.

Accepted Answer

The test or decision in a looping structure is used to check whether the loop should continue executing or should be terminated. It is used to evaluate a condition, and if the condition is true, the loop will execute again. If the condition is false, the loop will end.

Question 2

"Desk-checking" refers to
A) the continual problem programmers have with losing things.
B) timing a program to see how fast it completes its tasks.
C) testing an algorithm at the flowchart stage using several different kinds of data.
D) having a fellow programmer read your pseudocode to be sure it is understandable.

Accepted Answer

Desk-checking involves testing an algorithm at the flowchart stage using different types of data to ensure its correctness.

Question 3

What does the circle flowchart symbol represent?
A) input/output
B) terminal
C) decision
D) connector
E) process

Accepted Answer

The circle flowchart symbol represents a connector, which is used to connect different parts of a flowchart, often indicating a jump from one point in the process to another.

Question 4

A flowchart is an arrangement of geometric shapes connected by arrows.

Accepted Answer

A flowchart is a graphical representation of a process or algorithm, consisting of geometric shapes connected by arrows representing the flow of the process.

Question 5

A top-down chart is the same thing as a flowchart.

Accepted Answer

A top-down chart is a type of diagram that focuses on the hierarchy of tasks, while a flowchart is a diagram that shows the movement or progression of a process or system. While there may be some similarities between the two, they are not the same thing.

Question 6

The divide-and-conquer-method of problem solving breaks a problem into large, general pieces first, then refines each piece until the problem is manageable.

Accepted Answer

The divide-and-conquer method consists of breaking down a problem into smaller, more manageable pieces, and then solving each piece individually. This approach allows for easier problem-solving by breaking a larger problem into more approachable parts.

Question 7

A graphical depiction of the logical steps to carry out a task and show how the steps relate to each other is called a(n)
A) flowchart.
B) pseudocode.
C) algorithms.
D) hierarchy chart.

Accepted Answer

A flowchart is a graphical representation of a process or algorithm in which steps are represented by symbols and connected by arrows to show the logical sequence of the steps. Pseudocode is a form of writing code that combines natural language and code-like syntax, while algorithms are sets of rules for solving a problem or completing a task. A hierarchy chart, on the other hand, shows the relationships and order of execution of modules or subroutines within a larger program or system.

Question 8

Pseudocode and flowcharts are two different tools or methods used in planning a solution to a problem.

Accepted Answer

Pseudocode is a textual representation of a solution, while flowcharts use symbols to represent different steps and decisions in a process. They are both used in the planning phase of problem-solving.

Question 9

If a problem is very complex, extensive design prior to coding will actually delay the completion of the project.

Accepted Answer

Extensive design prior to coding helps to identify potential issues and solutions, allowing for a more efficient coding process that may ultimately save time in the long run.

Question 10

What does the diamond flowchart symbol represent?
A) input/output
B) terminal
C) decision
D) connector
E) process

Accepted Answer

The diamond flowchart symbol represents a decision point where the flow of the chart can diverge based on a yes or no answer. It is also known as a decision node.

Question 11

Suppose your supervisor at work wants you to write a program to accomplish a task that he has specified. However, he has not let you know which computer language to use. It is still possible to design the program in pseudocode.

Accepted Answer

Pseudocode is a language-independent way of outlining the steps in a program. It can be used to design a program regardless of the programming language that will eventually be used to implement it.

Question 12

During the design phase, all errors will be caught by Visual Basic's smart editor.

Accepted Answer

While Visual Basic's smart editor can catch some errors, it is not foolproof and errors may still occur during the design phase. A thorough testing process is necessary to ensure the program is error-free.

Question 13

Although a flowchart (as its name suggests) depicts data flow very well, it is not easily modified once written.

Accepted Answer

Flowcharts can be difficult to modify once they are created, as they require re-drawing or editing the entire chart.

Question 14

What does the rectangle flowchart symbol represent?
A) input/output
B) terminal
C) decision
D) connector
E) process

Accepted Answer

The rectangle flowchart symbol represents a process or activity. It indicates that some action will be taken or a task will be performed in the flowchart.

Question 15

Flowcharts, pseudocode, and top-down charts can be used to solve problems only in Visual Basic.

Accepted Answer

Flowcharts, pseudocode, and top-down charts can be used to solve problems in any programming language, not just Visual Basic. They are universal problem-solving tools that can be applied to various programming languages.

Question 16

What does the "rectangle with rounded sides" flowchart symbol represent?
A) input/output
B) annotation
C) decision
D) start/stop
E) process

Accepted Answer

The answer of What does the "rectangle with rounded sides"...
