Understanding Subprograms and Subroutines

What is another term for sub-programs?

• Subfields

• Subsections

• Subclasses

• Subroutines

What does a sub-program or subroutine do?

• Creates new variables

• Deletes data

• Starts the program

• Performs a specific task

How often can sub-programs be used in a program?

• Repeatedly

• A limited number of times

• Twice

• Only once

What is the main advantage of using sub-routines in programming?

• They make programs run faster

• They reduce the size of the code

• They can be reused

• They are only used in large programs

How would you define a subroutine called Add in Python ?

• def add():

• def add()

• Def Add()

• def Add():

What are parameters used for?

• To run a subroutine

• To define a subroutine

• The number of lines of code in a subroutine

• To pass data to a subroutine

Data can be passed out of a subroutine by using the following command

• pass

• return

• export

• output

A local variable used in a subroutine is defined as (select all that apply)

• A variable that only exisits while the subroutine is executing

• A variable that can be used outside of the subroutine

• A variable that is only accessed within the subroutine

• A variable that can be used in the subroutine and in the main program as well

A global variable is defined as (select all that apply)

• A variable that can be used in any part of your program including subroutines

• A variable that can only be used within the scope of a subroutine

• A variable that can only be used in your main program and not in subroutines

• A variable whose value does not change

5. Why is it generally better to use local variables instead of global variables?

• They prevent accidental modification of global variables from different parts of your code.

• They improve code readability by making it clear where variables are used.

• Because Mrs Milliner said so

• The code will run faster
