Thinking Procedurally

What was a common practice in early, unstructured computer programming?

• Using subroutines
• Utilising 'goto' statements

• Using function calls
• Implementing recursion

What term is another way to describe "unstructured code"?

• Linear code
• Structured code
• Spaghetti code
• Hierarchical code

In structured programming, what are the three main control structures?

• Sequence
• Branching
• Selection
• Iteration

What does the "sequence" construct in structured programming involve?

• Executing statements in random order
• Executing statements one after another

• Choosing between different code blocks
• Repeating a code block until a condition is met

Which of the following is NOT a keyword typically used to express a "selection" control structure?

• if
• then
• else
• do

What does the "iteration" control structure in structured programming involve?

• Executing a block of code only once
• Executing a block of code more than once

• Executing a block of code based on the result of a test

• Executing a block of code in a random order

What is one benefit of splitting code into smaller subroutines?

• It makes the code harder to test and debug
• It increases the amount of repeated code
• It reduces the amount of repeated code
• It prevents code reuse

What does a structure diagram (hierarchy chart) show?

• How to complete specific tasks
• How a complex application is broken down into modules
• How to write code more efficiently
• How to troubleshoot code errors

What do the modules at the top of a structure diagram / hierarchy chart typically represent?

• The most complex tasks
• The least broken-down subtasks
• The subroutines in a program
• The documentation requirements

What is one benefit of using a structure diagram /hierarchy chart in software development?

• It ignores the order of code execution.

• It removes the need for code debugging.

• It helps teams work on different parts of an application

• It contains detailed information on how tasks should be completed
