3.3 Control Structures

• The sequence control structure executes instructions in the order they are written.
• In a sequence control structure, instructions are executed one after the other.
• Match the control structure with its example:

  Sequence ↔️ `print("Hello"); print("World");`

  Selection ↔️ `if x > 0: print("Positive")`

  Iteration ↔️ `for i in range(5): print(i)`
• What are the two main types of loops used in programming?

  `for` and `while`
• What is the primary purpose of the selection control structure?

  Choose execution paths
• Which control structure allows programs to make decisions based on conditions?

  Selection
• What is the main purpose of control structures in managing program flow?

  Determine execution sequence
• Why are control structures important for creating dynamic programs?

  Enable adaptive behavior
• The `if-else` statement is used in selection to make decisions based on conditions.

  True
• What is the role of control structures in determining the order of instruction execution?

  Control program flow
• What type of loops are used in iteration to repeat a set of instructions?

  `for` and `while`
• Iteration control structures repeat a set of instructions using loops such as `for` and while.
• Loops are used in iteration control structures to repeat a set of actions.
• What is the primary purpose of control structures in managing program flow?

  Determine execution sequence
• Why are control structures important for creating dynamic programs?

  Enable adaptive behavior
• The `if-else` statement is used to choose between different execution paths based on a condition.

  True
• Mastering control structures is crucial for writing efficient, flexible, and responsive applications.


  True
• The `if-else` statement executes one block of code if the condition is true and another block if it is false.


  True
• The `if-else` statement evaluates a condition
• Why are selection control structures important in programming?

  Enable programs to adapt
• Sequence control structures execute instructions in the order they are written.


  True
• What is the primary purpose of control structures in managing program flow?

  Determine execution sequence
• How are instructions executed in a sequence control structure?

  In sequential order
• The `if-else` statement evaluates a condition
• The two primary types of loops are for and while loops.
• A for loop is used to iterate a specific number of times or to loop over each element in a collection.
• A nested control structure is one control structure placed inside another control structure to handle complex scenarios.
• Order the main types of control structures:

  1️⃣ Sequence

  2️⃣ Selection

  3️⃣ Iteration
• Control structures enable programmers to create dynamic and responsive programs.


  True
• What is the primary purpose of control structures in programming?

  Manage program flow
• Control structures are not essential for creating dynamic programs.

  False
• Control structures allow programmers to structure their code effectively by managing program flow
• The iteration control structure uses loops to repeat instructions multiple times
• Selection control structures use conditional statements to choose between different paths
• Selection control structures enable programs to adapt their behavior based on user input.


  True
• The `while` loop repeats a block of code as long as a condition is true.


  True
• Python uses indentation for code blocks, while Java uses curly braces {}.


  True
• Python uses 'elif' for multiple conditions, while Java uses 'else if'.


  True
• What replaces curly braces in Python for defining code blocks?

  Indentation
• Nested control structures enhance a program's ability to handle complex scenarios.
