48. Programming 1 : Intro to Subroutines

What is a subroutine?

• A unique type of variable

• A block of code with a unique identifiable name

• A special kind of loop

• A programming language

Why are subroutines used?

• To increase the size of the program

• To make the program run faster

• To break down a big problem into manageable parts

• To make the program more complex

What are the benefits of using subroutines?

• Makes it easier to code, test, and debug

• Makes the code harder to debug

• Increases the need to duplicate code

• Decreases code reusability

How can you identify a subroutine in a program?

• By the file size

• By the number of lines in the code

• By the color of the text

• By the use of keywords 'procedure' or 'function'

What is the typical structure of a program using subroutines?

• Main program at the top, subroutines at the bottom

• Random placement of subroutines and main program

• Subroutines in the middle, main program at the top

• Subroutines at the top, main program towards the end

What happens when a subroutine is called in a program?

• The program jumps to the subroutine, executes it, then returns

• The subroutine is deleted

• The program stops

• The program skips the subroutine

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

• A procedure returns a value

• There is no difference

• A function cannot take parameters

• A function should always return a value

What should a subroutine be designed to do?

• Perform multiple tasks

• Perform one task or action

• Connect to the internet

• Store data

How does using subroutines affect program development?

• Allows different parts to be worked on simultaneously

• Slows down development

• Makes no difference

• Prevents testing until completion
