Contructs & Variables A-level

Which construct allows decisions to be made in code?

• Functions/Procedures
• Sequence
• Selection
• Loops

Why is good variable naming important in programming?

• To slow down program execution
• To easily identify and use variables throughout the code
• To make the code unreadable
• To confuse other programmers

Which construct is used when you need to repeat a block of code multiple times?

• Selection
• Loops
• Functions/Procedures
• Sequence

What is the role of constructs in a program?

• Manipulating data
• Naming variables
• Controlling the flow of execution
• Storing data

What is the process of variable declaration?

• Assigning a value to a variable
• Specifying the type of data a variable will hold
• Creating a loop with a variable
• Displaying the variable on the screen

What is the most basic form of construct where instructions are executed one after another?

• Selection
• Loops
• Functions/Procedures
• Sequence

What is the purpose of assigning a value to a variable?

• To declare the variable
• To confuse other programmers
• To specify the type of data the variable will hold
• To change the contents of the variable

How do good naming conventions impact code readability?

• They make the code more confusing
• They slow down program execution
• They improve code readability and maintainability
• They have no impact on code quality

Which construct is used to repeat a block of code until a certain condition is met?

• Selection
• Loops
• Functions/Procedures
• Sequence

What do functions/procedures allow you to do in programming?

• Repeat code multiple times
• Make decisions in code
• Store data in variables
• Group code into reusable blocks
