Project : 1. ATM Machine

- We are writing a program for an ATM Machine

- Ask the user to enter the 5 Digit Card Number

- Ask the user to enter the 4 Digit Pin

- Ift the user provides the credentials correctly prompt him the following opotions

- CHECK BALANCE

- WITHDRAW THE AMOUNT

- DEPOSIT THE AMOUNT

- QUIT THE PROGRAM

Project : 2. Furtune Game

-The Player will be given 5 Turns to guess a number lets say "X"

-After Each Attempt Your Program will do:-

-If the player's entered number is less than the actual number X then show the output the player that his guess is less than the actual number X and show him the remaining guess out of 5.

-If the player's entered number is Greater than the actual number X then show the output the player that his guess is Greater than the actual number X and show him the remaining guess out of 5.

-If he has no tries left show output message player lost the GAME and show him the number X.

-If players entered number is equal to X then show output that he won and shoe him th number of tries taken.

-The Number X will be Between - 0 to 100.

code-

      import scala.io.StdIn.readLine
      import scala.util.control.Breaks._

      object Main{
      def main(args: Array[String]): Unit = {
      var X = 50
      var gamestatus = "Lost"
      breakable() 
      {
      for (w <- 1 to 5) 
      {
      var x = readLine("Enter Your Number")
      var guess = x.toInt


    if (guess < X) {
      println("Your guess is less than X")
      println(5 - w)
    } else if (guess > X) {
      println("Your guess is Greater than X")
      println(5 - w)
    } else {
      println("You guessed it Correctly!!")
      println(w)
      gamestatus="Won"
      break()
    }

  }
}

       println("you lost the Game ")
