Scala & Spark-Master Big Data with Scala and Spark - Basic Functions

This video tutorial covers the implementation of basic banking functions using global variables. It explains how to create functions for checking balance, withdrawing, and depositing amounts. The tutorial also demonstrates handling user input and updating the balance accordingly. The use of global variables allows these functions to access and modify the balance variable within the global scope.

What is the initial value assigned to the global variable 'balance'?

• $50

• $100

• $150

• $200

What is the main purpose of the 'check balance' function?

• To deposit money

• To display the current balance

• To withdraw money

• To update the balance

Which parameter is expected by the 'withdraw' function?

• The account number

• The deposit amount

• The amount to withdraw

• The user's name

What happens if the withdrawal amount exceeds the available balance?

• A message is displayed indicating insufficient funds

• The amount is partially withdrawn

• The balance is updated

• The transaction is completed

What is the return type of the 'withdraw' function?

• Unit

• Boolean

• Integer

• String

What does the 'deposit' function do with the user-entered amount?

• Subtracts it from the balance

• Adds it to the balance

• Ignores it

• Multiplies it with the balance

How is the user prompted to enter the amount for deposit?

• By selecting from a list

• By entering it in a text field

• By clicking a button

• Through a dropdown menu
