Scala & Spark-Master Big Data with Scala and Spark - Prompting the Menu

This video tutorial guides viewers through setting up a basic project structure, focusing on user input handling and menu options. It explains how to use a do-while loop for repeated user interactions and demonstrates variable declaration and input handling. The tutorial also covers implementing conditional logic to process user choices and exit the loop when needed. The next video will introduce functions for specific tasks like checking balance and withdrawing funds.

What does the 'if' statement in the project structure primarily check?

• If the user has entered the correct password

• If the user has successfully entered credentials

• If the user has sufficient balance

• If the user wants to quit the program

Why does the instructor initially write the code in a single main function?

• To avoid using any loops

• To make the code more complex

• To prevent user input errors

• To allow for easier refactoring into functions later

What is the purpose of the do-while loop in the menu system?

• To limit the number of user inputs

• To execute the menu options only once

• To ensure the program runs without errors

• To allow users to repeatedly choose actions until they quit

Which action is NOT part of the menu options presented to the user?

• Deposit amount

• Withdraw amount

• Transfer funds

• Check balance

What is the role of the variable 'input' in the user interaction process?

• To display the user's transaction history

• To save the user's menu choice

• To calculate the user's withdrawal amount

• To store the user's balance

How does the program determine when to exit the do-while loop?

• When the user enters '0'

• When the user enters an invalid option

• When the user enters '3'

• When the user enters '4'

What is the primary function of the if-else statements in the menu logic?

• To display error messages

• To process different menu options based on user input

• To validate user credentials

• To initialize the program variables
