Scala & Spark-Master Big Data with Scala and Spark - Project Overview - Functions

This video tutorial guides viewers through creating a simple ATM program. It covers user input for card numbers and PINs, checking credentials, and providing options like checking balance, withdrawing, depositing, and quitting. The tutorial emphasizes using variables, loops, and functions, encouraging viewers to practice and apply learned concepts.

What is the first step in creating the ATM program?

• Ask the user to enter their name

• Ask the user to enter a five-digit card number

• Ask the user to select a language

• Ask the user to enter their email address

What should the program do if the user enters incorrect credentials?

• Automatically reset the PIN

• Allow the user to try again up to three times

• Lock the user out immediately

• Send an alert to the bank

How should the program handle a withdrawal request that exceeds the account balance?

• Cancel the transaction without any message

• Automatically transfer funds from another account

• Prompt the user with a message about insufficient funds

• Allow the withdrawal and show a negative balance

What is the purpose of using global variables in the ATM program?

• To store temporary data that is not needed after the program ends

• To allow different parts of the program to access and modify shared data

• To make the program run faster

• To ensure data is only accessible within a single function

What should happen when the user chooses to quit the program?

• The program should restart

• The program should display a farewell message and exit

• The program should log the user out and return to the main menu

• The program should save the user's session for later
