CS Unit 5: Functions and Subroutines

What is an advantage of using subroutines?

• Faster execution time

• Limited code organization

• Easier to reuse code

• Easier to spot errors

What is the difference between a function and a procedure?

• Functions are faster than procedures

• Procedures return values, functions do not

• Functions return values, procedures do not

• Procedures are used for input only

What does a function do in a program?

• Handle user input errors

• Execute a specific set of commands

• Print statements to the console

• Calculate or process a value

What happens when the return line is executed in a function?

• Function terminates and returns a value

• Function continues executing code

• Function prints a message to the console

• Function restarts from the beginning

What is the main benefit of using functions in programming?

• Code obfuscation

• Code duplication

• Code complexity

• Code reusability

What is the purpose of an argument in a function?

• Values returned by the function

• Values passed into the function

• Values printed to the console

• Values stored in memory

What is the significance of using trace tables in functions?

• Investigate function behavior

• Handle user input errors

• Terminate the program

• Print messages to the console

XOR is another logical operator. It stands for exclusive or. It will only output as True if one input is True. If they are both True, then it will evaluate as False.

• True

• False

Unlike AND and OR, Python does not have a built-in operator for XOR. You would need to create your own function to evaluate XOR.

• True

• False

What is a subroutine?

• A sequence of instructions with an identifiable name

• A random set of code lines

• A type of variable

• A loop structure
