A-level Subroutine

What is a subroutine in programming?

• A type of variable used to store data.
• A block of code with a unique name.
• A method for organizing files in a project.
• A graphical representation of a program.

What is the relationship between subroutines and debugging?

• Subroutines must be removed before debugging.
• Subroutines are not relevant to debugging.
• Subroutines make debugging easier by isolating code.
• Subroutines complicate debugging.

What is a key benefit of modular programming?

• It increases the size of the code.
• It allows for easier updates and maintenance.
• It eliminates the need for testing.
• It reduces the need for comments.

Which of the following best describes the role of subroutines in programming?

• They eliminate the need for comments in the code.
• They help break down larger problems into smaller, manageable ones.
• They are only used in object-oriented programming.
• They increase the complexity of the code.

Which of the following is NOT a characteristic of a procedure?

• It can return a value.
• It carries out a specific task.
• It does not return a value.
• It is a block of code.

What is the primary purpose of using functions in programming?

• To create user interfaces.
• To perform calculations and return values.
• To store data permanently.
• To manage memory allocation.

What distinguishes a function from a procedure?

• Procedures are always shorter than functions.
• Functions carry out a task and return a value, while procedures do not.
• Procedures return a value, while functions do not.
• Functions do not require parameters.

In the context of object-oriented programming, what are procedures and functions referred to as?

• Modules
• Methods
• Attributes
• Classes

How can you identify a subroutine in a program?

• It is always written in uppercase letters.
• It starts with 'start' and ends with 'finish'.
• It contains at least one loop.
• It starts with 'procedure' or 'function' and ends with 'end procedure' or 'end function'.
