GCSE Programming Constructs

Which of the following programming constructs is primarily used to execute a block of code repeatedly?

• Function
• Sequence
• Selection
• Iteration

What is a key characteristic of selection (branching) in programming?

• It organizes code into functions.
• It repeats code a specific number of times.
• It allows the program to choose different paths based on conditions.
• It executes code in a fixed order.

Which of the following best describes the concept of sequence in programming?

• Executing multiple instructions simultaneously.
• Executing instructions in a random order.
• Executing one instruction after another.
• Executing instructions based on user input.

What is an example of a typical selection construct in programming?

• if statement
• sequence statement
• for loop
• while loop

What is the primary purpose of selection (branching) in programming?

• To store data temporarily during execution.
• To allow the program to go in various directions based on a condition.
• To execute instructions in a fixed order.
• To repeat sections of code multiple times.

What is the role of the else statement in an if statement?

• To execute code if the condition is true.
• To execute alternative code if the condition is not met.
• To repeat the if statement multiple times.
• To terminate the program if the condition is false.

Which programming construct allows for repeating sections of code?

• Sequence
• Iteration
• Selection
• Function

Which of the following statements about counter-controlled loops is true?

• They cannot be nested within other loops.
• They are typically implemented using for loops.
• They require a condition to be checked before each iteration.
• They are used when the number of iterations is not known.

Why might a programmer choose to use a for loop instead of a while loop?

• When the loop needs to execute indefinitely.
• When no conditions are involved.
• When the number of iterations is known ahead of time.
• When the number of iterations is not known.

In programming, what does a for loop primarily control?

• The execution of code based on user input.
• The number of iterations when the count is known.
• The execution of code until a condition is met.
• The random selection of code paths.
