Programming Concepts Quiz

What is a subroutine?

• A named, out of line block of code that may be executed (called) by simply writing its name in a program statement

• A data item that is passed to a subroutine when it is called

• A named, out of line block of code that returns a value

• A way that the module can be accessed and used

What is a parameter in programming?

• A named, out of line block of code that may be executed (called) by simply writing its name in a program statement

• A data item that is passed to a subroutine when it is called

• A named, out of line block of code that returns a value

• A way that the module can be accessed and used

What is the key difference between a function and a procedure?

• A function returns a value to the calling routine and uses the RETURN keyword, while a procedure does not return a value

• A function is a named block of code, while a procedure is not

• A function is used for structured programming, while a procedure is not

• A function is a data item passed to a subroutine, while a procedure is not

What does structured programming involve?

• Decomposition of the program into small manageable modules

• Passing data items to subroutines

• Returning values to the calling routine

• Accessing and using modules

What is an interface in programming?

• A named, out of line block of code that may be executed (called) by simply writing its name in a program statement

• A data item that is passed to a subroutine when it is called

• A way that the module can be accessed and used

• A named, out of line block of code that returns a value

What is the primary benefit of using subroutines in programming?

• They make the code run faster.

• They allow code to be reused and reduce repetition.

• They increase the complexity of the code.

• They make the code harder to maintain.

Which of the following is NOT a benefit of using subroutines?

• Code is easier to test.

• Code is easier to maintain/update.

• Code is harder to follow.

• Development time can be sped up.

What is the purpose of local variables in subroutines?

• They are accessible from anywhere in the program.

• They exist only within the scope of the subroutine.

• They are used to store global constants.

• They are used to store the return value of the subroutine.

Which of the following is a benefit of using local variables in subroutines?

• They increase the memory usage.

• They can be accessed from other subroutines.

• They reduce the chance of errors or changes being made to values unintentionally.

• They make the code run slower.

What is indicated by the term "parameters" in the context of subroutines?

• The return value of the subroutine.

• The variables declared within the subroutine.

• The values passed to the subroutine.

• The name of the subroutine.
