What is a subroutine in programming?

• A specific programming language

• A type of error in code

• A block of code with a unique identifiable name

• A unique type of variable

What are the two main types of subroutines covered in the video?

• Loops and Conditions

• Variables and Constants

• Classes and Objects

• Procedures and Functions

What is the difference between a procedure and a function?

• A function can only be used once, but a procedure can be used multiple times

• A procedure is used in Java, but a function is used in Python

• A function returns a value, but a procedure does not

• There is no difference

In object-oriented programming, what are procedures and functions collectively referred to as?

• Variables

• Methods

• Classes

• Objects

How can you identify a subroutine in a program?

• By the use of specific keywords like 'variable' or 'constant'

• By the color of the text in the code editor

• By the indentation level of the code

• By the use of keywords like 'procedure' or 'function' at the start

What is the purpose of using subroutines in programming?

• To increase the size of the program

• To make the code run faster

• To help break down problems into smaller, manageable parts

• To make the code look more complex

What is a 'procedure call' in programming?

• A type of data structure

• A command to stop the program

• A request to access a website

• A call to another procedure within the program

What happens when a subroutine reaches an 'end' statement?

• The program crashes

• It returns to where it was called and continues execution

• The computer shuts down

• It repeats the subroutine

Why are programs easier to debug when written using subroutines?

• Because they run faster

• Because they are written in a single block of code

• Because they require less memory

• Because they are divided into smaller, manageable blocks of code

What is the advantage of grouping functions into a library?

• It allows for easy reuse across many different programs

• It changes the programming language automatically

• It makes the program run without errors

• It reduces the cost of software development
