Question 1

The problem analysis chart,the IPO chart,the structure chart,the algorithms,and the flowchart are all tools to be used in the development of a solution to a problem.

Accepted Answer

All of these tools are commonly used in software development to help developers plan and visualize the steps needed to solve a problem.

Question 2

In a coupling diagram,all variables are indicated in the same way.

Accepted Answer

In a coupling diagram, different types of variables are indicated using different symbols or notations. For example, inputs are usually represented by arrows pointing into the system, while outputs are represented by arrows pointing out of the system. Internal variables may be represented using different shapes or symbols than inputs and outputs.

Question 3

The IPO chart:

Accepted Answer

B

Question 4

Of the several problem solving tools introduced,which provides the BEST view of the alternative solutions

Accepted Answer

The Problem Analysis Chart provides a clear visualization of the different alternative solutions with their respective advantages and disadvantages. It helps in weighing the pros and cons of each solution and selecting the most feasible one. The Flowchart and IPO Chart focus more on the steps involved in the solution rather than providing a comprehensive comparison of alternatives. The Algorithm provides a step-by-step procedure for solving a problem but may not necessarily show alternative solutions.

Question 5

The algorithm and the flowchart are the same thing.

Accepted Answer

While they are related, algorithms and flowcharts are not the same thing. An algorithm is a step-by-step procedure for solving a problem or achieving a goal, while a flowchart is a graphical representation of that process. A flowchart can be one way to visually represent an algorithm, but it is not the same thing as the algorithm itself.

Question 6

The sequential logic structure:

Accepted Answer

Sequential logic structures can indeed be used with other logic structures, are utilized in almost all solutions, and typically conclude with a return, an end, or an exit statement.

Question 7

It is not important to indicate what documentation is needed as you are developing the solution.

Accepted Answer

It is important to indicate what documentation is needed as you are developing the solution in order to ensure that the necessary information is gathered and recorded throughout the development process. This can include documentation such as requirements documents, design documents, user manuals, and test plans.

Question 8

The rectangle in a flowchart indicates:

Accepted Answer

The rectangle in a flowchart indicates a process. It is used to represent a specific operation or action that is required to be executed as part of the overall process.

Question 9

Of the several problem solving tools introduced,which provides the BEST view of the pseudocode

Accepted Answer

An algorithm usually provides the most detailed and specific view of pseudocode. It outlines the steps of the solution in a clear and concise manner, making it easy to translate into actual code. While flowcharts and IPO charts can provide a visual representation of the steps, they may not provide the necessary level of detail for implementation, and problem analysis charts focus more on identifying the problem and potential solutions rather than outlining the specific steps of the solution.

Question 10

The flattened ellipse in a flowchart indicates:

Accepted Answer

The flattened ellipse, often referred to as a terminal symbol, is used in flowcharts to denote the start or stop of a process or module.

Question 11

The Return instruction and the Exit instruction are exactly the same and can be used interchangeably.

Accepted Answer

The Return instruction is used in functions to return a value to the calling code, while the Exit instruction is used to terminate a program or a loop. While they both may have similar effects in certain situations, they are not interchangeable.

Question 12

Of the several problem solving tools introduced,which provides the BEST view of the program logic in two-dimensions.

Accepted Answer

A flowchart is a graphical representation of the program logic in two dimensions, showing the flow of control and data through the program. It provides a clear visualization of the program structure and makes it easier to identify potential issues or areas for improvement. While algorithms, problem analysis charts, and IPO charts are all useful problem-solving tools, they do not provide the same level of clarity and simplicity as a well-designed flowchart. Therefore, the best choice for viewing program logic is a flowchart.

Question 13

The algorithm of a module always starts with:

Accepted Answer

The module algorithm should always start with the name and number of the module. This ensures that the module is properly identified and can be easily referenced by other code or developers. Starting with a flattened ellipse or the name of the program or developer is unnecessary and does not provide useful information about the module.

Question 14

The interactivity (structure)chart is developed by:

Accepted Answer

The interactivity (structure) chart is developed through the process of breaking the total solution into functional parts called modules and grouping similar types of modules. Then, the names and numbers of the modules are placed in rectangles and arranged hierarchically to demonstrate the relationship between modules. Therefore, all of the options (A, B, and C) are necessary for developing the interactivity (structure) chart.

Question 15

The Return instruction is used to end a module.

Accepted Answer

The Return instruction is used to end a function or a method, not a module in programming.

Question 16

An instruction has two parts: the general instruction followed by the specifications on how to execute the instruction.

Accepted Answer

This statement is true. An instruction includes the general statement of what needs to be done as well as the specific steps that need to be taken to execute the instruction correctly.

Question 17

The word end and exit can be used interchangeably according to the desire of the developer.

Accepted Answer

While the words end and exit may have similar meanings, they are typically used in different contexts in programming. End typically refers to the conclusion of a program or process, while exit is often used to indicate the termination of a specific function or subroutine. It is important to use the correct terminology in order to avoid confusion and ensure clear communication within the programming community.

Question 18

The equals sign in an assignment statement really means equals to.

Accepted Answer

The equals sign in an assignment statement is actually an assignment operator, which assigns the value on the right-hand side to the variable on the left-hand side. It is not an equality operator that checks if both sides are equal.

Question 19

The external documentation is:

Accepted Answer

The answer of The external documentation is:
...

Question 20

The sequential logic structure allows decisions to be made.

Accepted Answer

Sequential logic structure involves executing instructions in a specific order without making decisions or branching, unlike conditional or decision-making structures.
