Year 10 Subroutines Quiz

What is the concept of decomposition in programming?

• Breaking down a program into smaller, manageable parts

• Combining all parts of a program into a single function

• Increasing the number of parameters in a subroutine

• Writing code without using subroutines

What is a subroutine in programming?

• A tool to debug programs

• A sequence of instructions to perform a specific task with an identifiable name

• A type of variable used to store data

• A sequence of instructions to perform a specific task

When is a subroutine executed in a program?

• When the program is compiled

• When the subroutine is defined using 'def'

• When the subroutine is called

• Subroutines are executed automatically when the program starts

What is the purpose of parameters in a subroutine?

• To define the type of subroutine

• To allow values to be passed into the subroutine

• To specify the return value of the subroutine

• To name the subroutine

In the given code snippet, what are the arguments passed to the 'calculate' subroutine?

• 'a' and 'b'

• 'num1' and 'num2'

• 10 and 15

• 'answer' and 'print'

What happens to the control flow when a subroutine call is encountered?

• The control flow continues to the next statement in sequence.

• The control flow is terminated.

• The control flow differs and runs the statements in the subroutine.

• The control flow pauses indefinitely.

What is one of the advantages of using subroutines in programming?

• To repeat a set of instructions multiple times

• To increase the complexity of the code

• To make the code less efficient

• To display output without performing any calculations

How can a subroutine return a value to the part of the program that called it?

• By printing the value inside the subroutine

• Using a global variable

• By using the return statement

• Subroutines cannot return values

Which of the following best describes the concept of 'recursion' in programming?

• A subroutine that calls another subroutine

• A subroutine that calls itself

• Breaking down a program into smaller parts

• Executing a subroutine multiple times

What is the significance of the 'scope' of a variable within a subroutine?

• It determines the variable's value throughout the program

• It restricts the variable's visibility and usage to within the subroutine

• It makes the variable accessible from any part of the program

• It has no significance in modern programming languages
