7.5 Structure diagrams

What does decomposition mean in the context of problem-solving?

• Combining multiple problems into one

• Ignoring complex problems

• Breaking a complex problem into smaller parts

• Solving problems randomly

How can structure diagrams help in problem decomposition?

• Avoid solving problems

• Create new problems

• Break down complex problems into manageable parts

• Combine all problems into one diagram

What approach is used to create structure diagrams?

• Random guessing

• Trial and error

• Stepwise refinement

• Ignoring the problem

What is the top-level node in a structure diagram typically named?

• Initial analysis

• Main task

• Overall program name

• Complex problem

How many main areas is the company wage program broken down into?

• 1

• 4

• 2

• 3

What are the three main areas of the company wage program?

• Input the employees details, Calculate their pay, Produce pay slips

• Input data, Calculate deductions, Produce reports

• Input hours worked, Calculate overtime, Produce invoices

• Analyze data, Calculate taxes, Print checks

What is the next level of the structure diagram after the main tasks?

• Level 1 modules

• Complex problems

• Gross pay and deductions

• Random tasks

How is the process of breaking down complex stages further described?

• Combine them into larger chunks

• Ignore them

• Break them into smaller manageable chunks

• Solve them all at once

What could 'calculate deductions' be broken down into?

• Income tax, National insurance, Paid sick days, Pension contributions

• Overtime pay, Bonus pay, Deductions, Benefits

• Gross pay, Gross deductions, Net pay, Taxes

• Income tax, National insurance, Non-paid sick days, Pension contributions

What is the end goal of breaking down stages in a structure diagram?

• Ignore the tasks

• Achieve one task at each node, which can be coded as a single module

• Solve all tasks simultaneously

• Combine all nodes into one task
