2.2.4 Structured programming

• In structured programming, flow control uses sequence, selection, and iteration
• Structured programming simplifies program structure by eliminating the need for goto
• Structured programming improves code readability by using logical control structures like loops and if-else
• Structured programming results in code with high readability
• Maintainability in structured programming is enhanced by clear modularity.


  True
• The use of `goto` statements can lead to complex, difficult-to-follow program logic
• Match the control structure with its description.

  Sequence ↔️ Default flow of execution

  Selection ↔️ Executes different code paths based on conditions

  Iteration ↔️ Repeats a block of code
• What is an example of iteration in structured programming?

  for loop
• Order the steps in decomposing the `calculate_total_cost` function into smaller functions.

  1️⃣ Calculate subtotal

  2️⃣ Calculate tax

  3️⃣ Calculate total
• What is a key feature of unstructured programming that structured programming avoids?

  goto statements
• The use of `goto` statements can lead to complex, difficult-to-follow program logic
• What is an example of a sequence control structure?

  x = 5; y = 10; z = x + y;</latex>
• What is an example of an iteration control structure?

  for (let i = 0; i < 5; i++) { ... }</latex>
• Which approach has higher readability, function decomposition or a monolithic approach?

  Function Decomposition
• Which control structure enables decision-making in structured programming?

  Selection
• What is structured programming defined as?

  A programming methodology
• Why is debugging easier in structured programming?

  Modular code blocks
• What are the three primary control structures in structured programming?

  Sequence, selection, iteration
• What is the main goal of structured programming regarding program flow?

  Avoid goto statements
• The selection control structure uses if-else
• The three basic control structures in structured programming are sequence, selection, and iteration.


  True
• Function decomposition reduces code complexity
• In structured programming, flow control relies on sequence, selection, and iteration.
• The basic control structures in structured programming control the flow of execution in a program.

  True
• Match the control structure with its description:

  Sequence ↔️ Statements are executed in order

  Selection ↔️ Executes different code paths based on conditions

  Iteration ↔️ Repeats a block of code multiple times
• The `if-else` statement is used in structured programming for selection
• Steps to decompose the 'calculate_total_cost' function

  1️⃣ Calculate subtotal

  2️⃣ Calculate tax

  3️⃣ Calculate total
• Modularity allows modules to be reused in different parts of the application
• Sequence executes statements in the order they appear.


  True
• Structured programming enhances code readability compared to unstructured programming.

  True
• Match the feature with the corresponding programming style:

  Flow Control ↔️ Sequence, Selection, Iteration

  Readability ↔️ High

  Goto Statements ↔️ Unstructured Programming
• Structured programming reduces complexity by eliminating goto statements.


  True
• Match the control structure with its description:

  Sequence ↔️ Statements executed in order

  Selection ↔️ Choice based on condition

  Iteration ↔️ Repeated execution of code
• What is the purpose of the sequence control structure in structured programming?

  Execute statements in order
• Order the basic control structures used in structured programming.

  1️⃣ Sequence

  2️⃣ Selection (if-else)

  3️⃣ Iteration (for, while)
• In structured programming, an example of selection is the if-else statement.
• Function decomposition enhances code readability, reusability, and maintainability.

  True
• Structured programming avoids the use of `goto` statements to control program flow.

  True
• Match the benefit of structured programming with its example.

  Reduced Complexity ↔️ Replacing `goto` statements with `if` and `while` constructs

  Readability ↔️ Using loops and `if-else` statements instead of `goto`

  Maintainability ↔️ Modifying a specific function without affecting others
• The basic control structures in structured programming are sequence, selection, and iteration.
