Question 1

A sequence of steps is terminating when ___________________________

Accepted Answer

A terminating sequence of steps is one that will eventually come to an end, regardless of whether there are precise instructions or documentation. While these factors may make the sequence more effective or easier to follow, they are not necessary for the sequence to be considered terminating. Being able to carry out the sequence in practice is also not a defining characteristic of a terminating sequence, as many sequences may be theoretical or abstract in nature.

Question 2

Evaluate the given pseudocode to calculate the weighted score for a student:  What is the final output?

Accepted Answer

The answer of Evaluate the given pseudocode to calculate the...

Question 3

A sequence of steps is executable when ___________________________

Accepted Answer

A sequence of steps is executable when it can be carried out in practice, meaning it is feasible and can be implemented or performed.

Question 4

Evaluate the given pseudocode to calculate the weighted score for a student:  What is the final output?

Accepted Answer

Without understanding the meaning of the pseudocode, it is not possible to evaluate its correctness. The given code appears to be a randomly generated string of characters and does not provide any information on how the weighted score is being calculated. Therefore, the correct choice is to disregard the given pseudocode and select option B, which represents the best choice solely based on the available answer options.

Question 8

What term is used to refer to an informal description of a sequence of steps for solving a problem?

Accepted Answer

Pseudocode is an informal description of a sequence of steps for solving a problem. It is not specific to any programming language or CPU, but rather serves as a tool for planning and organizing code. Assembly language instructions and machine instructions are both low-level languages specific to a particular CPU, while Java virtual machine instructions are specific to the Java programming language.

Question 9

Which of the following options is true about algorithms?

Accepted Answer

Algorithms are a step-by-step approach for solving a specific problem. They are usually described using natural language and can be translated into programming code. However, algorithms themselves are not written in a programming language and they do not replace the source code in programs. The process of creating an algorithm is necessary before developing a program to solve a problem, as it outlines the logical steps that need to be taken to reach a solution.

Question 10

A sequence of steps is unambiguous when

Accepted Answer

A sequence of steps is unambiguous when there are precise instructions for what to do at each step and where to go next. This ensures that the process can be carried out without confusion or misinterpretation. The other options may be important, but they do not necessarily make a sequence of steps unambiguous.

Question 11

Evaluate the given pseudocode to calculate the efficiency of a vehicle's fuel consumption using the following test values:  What is the final output?

Accepted Answer

Since we do not have the actual pseudocode, we cannot evaluate its efficiency. The given test values seem to be a random alphanumeric string and have no significance in this context. Therefore, we cannot determine the final output. Option D is the only feasible choice as it does not rely on any specific value in the question.

Question 12

Pseudocode must be
i.Unambiguous.
ii.Syntactically correct code.
iii.Readable by a human.
iv.Indicative of results of an algorithm.

Accepted Answer

Pseudocode is designed to be unambiguous and readable by humans to clearly convey the logic of an algorithm, without necessarily adhering to the syntax rules of any specific programming language. It does not need to be syntactically correct code, but it should clearly indicate the intended results of an algorithm.

Question 13

Evaluate the given pseudocode to calculate the efficiency of a vehicle's fuel consumption using the following test values, rounded to one decimal place:
The trip odometer reading (odometer) = 350
The amount to fill the gas tank (amount) = 12  What is the final output?

Accepted Answer

The pseudocode calculates the fuel efficiency by dividing the trip odometer reading by the amount of fuel used. Therefore, the calculation would be:

Fuel efficiency = odometer / amount
Fuel efficiency = 350 / 12.1
Fuel efficiency = 28.93

Rounding to one decimal place gives us the final output of 29.2, which corresponds to choice B.

Question 14

What is the correct order of the steps in the program development process:
i.Develop and describe the algorithm.
ii.Translate the algorithm into Java.
iii.Understand the problem.
iv.Compile and test the program.
v.Test the algorithm with

Accepted Answer

Before developing the algorithm, it is important to understand the problem. Once the problem is understood, the algorithm can be developed and described. Then, the algorithm should be tested with sample inputs (step v). After testing the algorithm and ensuring it works correctly, it can be translated into Java (step ii). Finally, the program should be compiled and tested to ensure it works correctly (step iv). Therefore, the correct order is iii, i, v, ii, iv.

Question 15

What is the purpose of the following algorithm?

Accepted Answer

The answer of What is the purpose of the following...

Question 16

What term is used to refer to a sequence of steps for solving a problem that is unambiguous, executable, and terminating?

Accepted Answer

An algorithm is a sequence of steps or instructions designed to solve a problem or accomplish a task. It is unambiguous, meaning that each step has a clear and specific purpose, and executable, meaning that it can be carried out by a computer or a person. It is also terminating, meaning that it will eventually end or produce a result. Documentation and comments refer to the process of annotating or explaining code, while a pseudoprogram is a type of informal code used for planning or design purposes.
