Question 1

Pseudocode is
A) data that have been encoded for security.
B) the incorrect results of a computer program.
C) a program that doesn't work.
D) the obscure language computer personnel use when speaking.
E) a description of an algorithm similar to a computer language.

Accepted Answer

Pseudocode is a method of describing an algorithm using natural language statements, similar to but not quite as detailed as a programming language. It allows programmers to outline the logic of their program in a way that is easy to understand and read, without worrying about the specific syntax of a particular programming language.

Question 2

When starting a new program, it is best to start writing code as soon as possible to avoid wasting time thinking about it.

Accepted Answer

It is important to spend time planning and designing the program before starting to write code. This can save time and prevent errors in the long run.

Question 3

Suppose in the very early stages of the problem-solving process, your supervisor wants you to show her the relationships between the various processes that will be needed to solve the problem. The best way to do this would be to use
A) a top-down chart.
B) a flowchart.
C) a sample program.
D) pseudocode.

Accepted Answer

A flowchart is the best choice as it is a visual representation of processes, showing the relationships and connections between them. A top-down chart could also work, but it may not show the exact flow of processes as well as a flowchart. A sample program and pseudocode are not appropriate at this stage as they are both more detailed and specific to the actual implementation of the solution, rather than just showing the overall relationships between processes.

Question 4

Which of the following is NOT considered to be one of the three basic features of a program?
A) input
B) processing
C) output
D) store

Accepted Answer

The three basic features of a program are input, processing, and output. The fourth choice, "store," refers to the storage of data within a program, but it is not considered one of the three fundamental features.

Question 5

Software refers to the people who work with computer hardware.

Accepted Answer

Software refers to computer programs and applications, not the people who work with hardware.

Question 6

An algorithm is defined as:
A) a mathematical formula that solves a problem.
B) a tempo for classical music played in a coda.
C) a logical sequence of steps that solve a problem.
D) a tool that designs computer programs and draws the user interface.

Accepted Answer

An algorithm is a logical sequence of steps that solve a problem. It is not necessarily a mathematical formula but can be used to solve various types of problems, including mathematical ones. It is also not a tempo for classical music or a tool for designing computer programs.

Question 7

Although the documentation step is usually listed last in the problem-solving process, it should actually begin when the problem is first defined and continue through the problem- solving process.

Accepted Answer

Documentation is an ongoing process that should start as soon as the problem is identified and should be continued throughout the problem-solving process to ensure that all the steps taken are recorded accurately for future reference.

Question 8

Visual Basic uses a graphical user interface.

Accepted Answer

Visual Basic does use a graphical user interface (GUI) to allow the user to interact with the code visually.

Question 9

The person who actually runs a computer program is called a
A) user.
B) customer.
C) client.
D) tester.
E) runner.

Accepted Answer

The person who runs a computer program is typically referred to as a user, since they are utilizing the program for a specific purpose. Customers and clients may interact with the program, but they are not typically the ones running it directly. Testers may be involved in testing the program for bugs or issues, but they are not responsible for running it in a general sense. "Runner" is not commonly used terminology within the context of computer programming.

Question 10

Often a problem is too difficult to understand until one writes the program.

Accepted Answer

The answer of Often a problem is too difficult to...

Question 11

In most cases, a well-written program need not be tested.

Accepted Answer

Even a well-written program needs to be tested to ensure that it works correctly and meets the desired requirements. Testing helps to identify any bugs or errors that may have been missed during the writing process.

Question 12

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

Accepted Answer

The answer of What does the parallelogram flowchart symbol represent?
A)...

Question 13

The analysis and design steps of program planning are largely independent of the particular computer language the programmer is using.

Accepted Answer

Analysis and design steps are focused on understanding the problem, identifying requirements and developing a solution, which are language-independent tasks. Programming language is only used in the implementation step to code the solution.

Question 14

If you are writing a program that needs to repeat a series of calculations, what programming structure should you use to repeat the calculations?
A) sequence structure
B) decision structure
C) looping structure
D) any of the above

Accepted Answer

The looping structure allows the programmer to repeat a certain section of code for a given number of times or until a specific condition is met. This structure is appropriate for programs that require repetitive operations or calculations. The other two structures (sequence and decision) do not provide the capability to repeat calculations.

Question 15

Which of the following types of charts shows only the relationships between general program tasks without showing specific modules or directions for data flow?
A) top-down chart
B) flowchart
C) both A and B
D) neither A nor B

Accepted Answer

A top-down chart, also known as a hierarchy chart, shows the relationships between general program tasks without detailing specific modules or data flow directions.

Question 16

Which of the following is the proper order of procedures used in the problem-solving process?
A) design, analysis, coding, testing
B) analysis, testing, design, coding
C) analysis, design, coding, testing
D) analysis, design, testing, coding
E) design, testing, analysis, coding

Accepted Answer

The proper order of procedures in the problem-solving process, especially in software development or engineering, is analysis (understanding the problem), design (planning the solution), coding (implementing the solution), and testing (verifying that the solution works as expected).

Question 17

The process of finding and correcting errors in a program is called
A) pseudocoding.
B) debugging.
C) algorithms.
D) development cycles.

Accepted Answer

Debugging is the specific process of identifying and correcting errors in a program. Pseudocoding is the process of sketching out the structure of a program before actually writing the code. Algorithms are a set of instructions for solving a problem or completing a task. Development cycles encompass the entire process of software development, and while debugging is a part of it, it is only one component.

Question 18

A collection of lines of instruction is called a(n)
A) program.
B) algorithm.
C) system.
D) programmer.

Accepted Answer

A collection of lines of instruction is typically referred to as a program, which is a set of instructions or statements that perform a specific task when executed by a computer. An algorithm is a more specific, step-by-step set of instructions for solving a particular problem. A system refers to a group of interconnected components or parts that work together to achieve a common goal. A programmer is someone who writes code or programs.

Question 19

Which one of the following is NOT one of the three basic types of statement structures?
A) sequence
B) loop
C) decision
D) input/output

Accepted Answer

The three basic types of statement structures in programming are sequence, loop, and decision. Input/output is not considered a basic statement structure but rather an operation or action that can occur within any of the three basic structures. Sequence refers to the execution of statements one after another, loop refers to the repetition of a block of statements, and decision refers to executing statements based on certain conditions.

Question 20

Visual Basic is considered to be a
A) first-generation language.
B) package.
C) higher-level language.
D) machine language.

Accepted Answer

Visual Basic is a higher-level language, which means it is easier to write and read than low-level languages like machine language.
