Scala & Spark-Master Big Data with Scala and Spark - Solution (Default Arguments)

The video tutorial guides viewers through creating a series of functions to handle bill and discount calculations. It starts with functions to get user input for bill and discount amounts, then moves to applying discounts using default arguments. Finally, it covers printing the results and testing the functions with example inputs.

What is the primary purpose of the function to get the bill amount?

• To ask the user for the bill amount and return it

• To calculate the total bill

• To apply a discount to the bill

• To print the bill amount

Which function is responsible for asking the user to enter the discount amount?

• get_discount_amount

• print_bill

• get_bill_amount

• apply_discount

What happens if the discount entered is zero in the apply discount function?

• The discount is set to 5

• The discount is ignored

• A default discount of 10 is applied

• The user is asked to enter a new discount

What is the default discount value used in the apply discount function?

• 5

• 10

• 15

• 20

How does the apply discount function handle the discount parameter?

• It doubles the discount if it is zero

• It always uses the provided discount

• It uses a default discount if none is provided

• It ignores the discount if it is zero

What is the role of the print bill function?

• To calculate the total bill

• To apply a discount to the bill

• To ask the user for the bill amount

• To display the total and discounted bill amounts

In the print bill function, what is the expected output?

• Both the total and discounted bill amounts

• Only the discounted bill

• A message asking for the bill amount

• Only the total bill
