What is the primary purpose of a subroutine in programming?

• To execute the main program

• To provide a set of instructions that can be called upon separately from the main program

• To enhance the graphical user interface

• To connect to the internet

What is the difference between a procedure and a function in programming?

• A function returns a value back to the main program after execution, while a procedure does not

• A procedure returns a value back to the main program after execution, while a function does not

• A function is used only in Java, while a procedure is used only in Python

• A procedure is used to terminate the program, while a function is not

What does 'parameter passing' refer to in the context of subroutines?

• Passing control to different parts of the program

• Sending arguments to subroutines to use during their execution

• The process of exiting a subroutine and returning to the main program

• The method of looping through data within a subroutine

What is one of the primary benefits of using subroutines in programming?

• Reduces program size

• Increases processing speed

• Removes repeating code

• Enhances color scheme

Which of the following is NOT a benefit of using subroutines as mentioned in the text?

• Allows for easier debugging

• Improves the overall organization of the program's logic

• Simplifies user interface design

• Provides a structured approach to programming

What problem do subroutines help to solve when programming large applications?

• Difficulty in finding errors and editing code

• Lack of programming languages

• Insufficient data storage

• Low network bandwidth

What is a subroutine in programming?

• A block of code with a unique name that executes when called

• A unique type of variable used to store data

• A method to debug programs

• A data structure used to organize information

What happens to the main program when a subroutine is called?

• The main program continues to execute other functions

• The main program terminates

• The main program pauses until the subroutine has finished executing

• The main program skips the subroutine execution

Which computational thinking strategies can be directly linked to use of subroutines?

• Decomposition and Abstraction

• Pattern Recognition and Algorithm Design

• Simulation and Evaluation

• Breaking into sperate calls

What is the main difference between a function and a procedure in programming?

• A function can execute faster than a procedure.

• A procedure can return values, but a function cannot.

• A function will return values back to the main program after it has been called, whereas a procedure will not.

• A procedure is used only in Python, while a function is used in all programming languages.
