Question 1

Most newer computer languages are unstructured and use syntax that lets you deal efficiently with sequence,selection,and looping.

Accepted Answer

Most newer computer languages are structured and designed to promote clear, efficient, and maintainable code, often using syntax that simplifies dealing with sequence, selection, and looping.

Question 2

A ____ can contain any number of tasks,but there is no chance to branch off and skip any of the tasks.
A) selection
B) sequence
C) decision
D) case

Accepted Answer

A sequence is a flow control structure that executes a set of tasks in a specific order. It contains a series of steps or tasks that must be completed in order, without any possibility of branching off or skipping any of the tasks. Therefore, a sequence is the best choice for the given scenario. Selection, decision, and case statements all involve branching off into different paths or making decisions based on certain conditions, which is not possible within a sequence.

Question 3

As programs get bigger,they get more confusing if they're not structured.

Accepted Answer

It is true that as programs grow in size, their complexity increases, and without proper organization and structure, it can become harder to understand and maintain.

Question 4

Programming structures can be combined in an infinite number of ways.

Accepted Answer

Programming structures, such as loops and conditional statements, can be combined and nested in various ways to achieve different outcomes and solve different problems. This allows for an infinite number of possible program structures.

Question 5

In code,it is perfectly correct for one branch of the selection to be a "do nothing" branch.

Accepted Answer

It is commonly used in programming to have a condition where if it is true, nothing happens, but if it is false, some action is taken. This can be represented by an empty code block or a comment stating that nothing should be done.

Question 6

In a structured program,structures can be stacked or connected to one another only at their start or exit points.

Accepted Answer

In a structured program, structures can be stacked or connected to one another only at their start or exit points. This is because the structured program follows the principle of control flow, where the program executes in a top-down manner and each structure has a single entry and exit point. Connecting structures at any other point would violate this principle and lead to an unstructured program.

Question 7

if-else examples can also be called ____,because they contain the action taken when the tested condition is true and the action taken when it is false.
A) do loops
B) repetition
C) single-alternative selections
D) dual-alternative selections

Accepted Answer

Dual-alternative selections, or if-else statements, contain two alternative actions to be taken depending on whether the tested condition is true or false.

Question 8

The following pseudocode is an example of a(n)____ structure. get firstNumber
Get secondNumber
Add firstNumber and secondNumber
Print result
A) decision
B) task
C) selection
D) sequence

Accepted Answer

The pseudocode follows a sequence structure as it executes each statement in order from top to bottom without any branching or decision-making.

Question 9

Programs that do not follow the rules of structured logic are ____ programs.
A) structured
B) scrambled
C) unstructured
D) disorganized

Accepted Answer

Unstructured programs do not follow the rules of structured logic. Structured programs follow a clear set of rules and conventions for defining the sequence, flow, and logic of the program. Scrambled and disorganized are not commonly used terms to describe program logic.

Question 10

With a(n)____ structure,you perform an action or task,and then you perform the next action in order.
A) loop
B) decision
C) assignment
D) sequence

Accepted Answer

A sequence structure is a series of actions or tasks that are performed in order, one after the other, until the end of the sequence is reached. In programming, a sequence structure is often used to break down a larger task into smaller, more manageable steps.

Question 11

Programs that use ____ code are so difficult to alter that when improvements are required,developers often find it easier to abandon the existing program and start from scratch.
A) preplanned
B) spaghetti
C) structured
D) rapid

Accepted Answer

Spaghetti code refers to code that is poorly organized and structured, making it difficult to understand and maintain. When changes or improvements are required, it can be difficult to determine the impact of the changes on the rest of the code, leading to errors and bugs. In some cases, it may be easier to start from scratch with a new program that is better organized and structured.

Question 12

Professional programmers find it just as easy to modify and maintain structured programs as unstructured programs.

Accepted Answer

Structured programs, which follow clear, predefined structures and patterns, are generally easier to modify and maintain than unstructured programs, which lack such organization and can be more chaotic and difficult to understand.

Question 13

A sequence can contain any number of tasks,but there is no chance to branch off and skip any of the tasks.

Accepted Answer

In a sequence, tasks must be completed in order without the ability to skip or branch off. Therefore, the statement is true.

Question 14

Whether you are drawing a flowchart or writing pseudocode,to represent decision outcomes you can use either: Yes and No,or True and False.

Accepted Answer

This statement is true, you can use either Yes and No or True and False to represent decision outcomes in both flowcharts and pseudocode.

Question 15

With a decision structure or ____ structure you ask a question,and,depending on the answer,you take one of two courses of action.
A) loop
B) branch
C) selection
D) logic

Accepted Answer

A selection structure is also known as a conditional or if-then-else structure. It allows you to ask a question and then choose between two different paths of execution based on the answer to that question.

Question 16

The popular name for logically snarled program statements is ____ code.
A) noodle
B) meatloaf
C) spaghetti
D) puzzle

Accepted Answer

The popular name for logically snarled program statements is "spaghetti code". This is because the program statements resemble a tangled mess of spaghetti noodles, making it difficult to follow and understand the code. A, B, and D are not commonly used terms for this concept.

Question 17

The following pseudocode is an example of a ____ structure. if firstNumber is bigger than secondNumber then
Print firstNumber
Else
Print secondNumber
A) sequence
B) selection
C) spaghetti
D) loop

Accepted Answer

The pseudocode is an example of a selection structure as it checks a condition (if firstNumber is greater than secondNumber) and chooses which action to perform (print firstNumber or print secondNumber) based on the result of the condition.

Question 18

A ____ is a basic unit of programming logic; each structure is a sequence,selection,or loop.
A) structure
B) block
C) program
D) subprogram

Accepted Answer

The question describes a structure as a basic unit of programming logic that can be a sequence, selection, or loop. Therefore, choice A (structure) is the best answer. Choice B (block) is not an accurate definition and choices C (program) and D (subprogram) are too broad and do not specifically fit the definition given in the question.

Question 19

You can replace any individual tasks or steps in a structured flowchart diagram or pseudocode segment with additional structures.

Accepted Answer

This is true. Structures like loops, conditionals, functions, and subroutines can be used to replace specific tasks or steps in flowchart diagrams or pseudocode segments.

Question 20

Any program,no matter how complicated,can be constructed using one or more of only four structures.

Accepted Answer

The statement is incorrect because any program can be constructed using three basic control structures: sequence, selection, and iteration.
