Understanding Structure Diagrams in Programming

What is the primary purpose of a structure diagram?

• To show the flow of a program.

• To visualise the hierarchy of modules in a program.

• To represent the data structures used in a program.

• To illustrate the user interface of a program.

In a structure diagram, what does a box typically represent?

• A variable.

• A loop.

• A module or sub-routine.

• A data type.

How are modules connected in a structure diagram?

• Using arrows to show the flow of execution.

• Using lines to show the relationship between them.

• Using different colours to group related modules.

• Using numbers to indicate the order of execution.

What is a key benefit of using structure diagrams in program design?

• They make it easier to write code directly.

• They help in breaking down complex problems into smaller parts.

• They eliminate the need for testing.

• They automate the process of program development.

Which of these is NOT a feature of a well-designed structure diagram?

• Clearly labelled modules.

• Hierarchical organisation.

• Detailed code within each module.

• Connections showing relationships between modules.

What does a hierarchical organisation in a structure diagram help to achieve?

• It ensures all modules are executed in parallel.

• It shows the sequence of user interactions.

• It clarifies the levels of control and dependency among modules.

• It provides a detailed view of the data flow.

Which of the following best describes a module in a structure diagram?

• A single line of code.

• A self-contained unit of code that performs a specific task.

• A collection of unrelated functions.

• A user interface component.

Why is it important to have clearly labelled modules in a structure diagram?

• To ensure the diagram is colourful.

• To make it easier to identify the purpose and function of each module.

• To increase the complexity of the diagram.

• To reduce the number of modules needed.

What is the role of lines in a structure diagram?

• To indicate the colour scheme of the program.

• To show the relationship and hierarchy between modules.

• To represent the data types used in the program.

• To display the user interface layout.

How can structure diagrams assist in the testing phase of program development?

• By eliminating the need for any testing.

• By providing a clear overview of the program's structure, making it easier to identify test cases.

• By automatically generating test scripts.

• By showing the exact output of the program.
