Program 2: Coin Toss Simulator
For this program, please implement Problems 12 and 13 in a single program (Gaddis, p812, 9E). Scans of these problems are included below.

Your program should have two sections that correspond to Problems 12 and 13:

1) As described in Problem 12, implement a Coin class with the specified characteristics. Run a simulation with 20 coin tosses as described and report the information requested in the problem. 2) For the second part of your program, write and instantiate a Game class. The Game class should contain Coin objects for a quarter, dime, and nickel, as described in the problem. Your Game class should have at least the following two public member functions:

a) void playGame(); This function will begin an individual game at the start and play it to completion (i.e., the balance is either $1 or greater than $1). It will report whether that particular game was won or not.

b) void runSimulation(); This function will play 50 games to completion and keep track of the number of wins and losses. It will then report that information to the user.   

Note that you will need the random number generator for these problems.   

12. Coin Toss Simulator Write a class named Coin. The Coin class should have the following field .A String named sideUp. The sideUp field will hold either "heads" or "tails" indicating the side of the coin that is facing up The Coin class should have the following methods .A no-arg constructor that randomly determines the side of the coin that is facing up (heads" or "tails") and initializes the aideUp field accordingly .A void method named toss that simulates the tossing of the coin. When the toss method is called, it randomly determines the side of the coin that is facing up ("heads" or "tails") and sets the sideUp field accordingly. A method named getSideUp that returns the value of the sideUp field Write a program that demonstrates the Coin class. The instance of the class and display the side that is initially facing up. Then. use a loop to toss the coin 20 times. Each time the coin is tossed, display the side that is facing up The program should keep count of the number of times heads is facing up and the number of times tails is facing up, and display those values after the loop finishes program should create an

13. Tossing Coins for a Dollar For this assignment you will create a game program using the Coin class from Programming Challenge 12. The program should have three instances of the Coin class: one representing a quarter, one representing a dime, and one representing a nickel When the game begins, your starting balance is $0. During each round of the game, the program will toss the simulated coins. When a coin is tossed, the value of the coin is CISC-185 Prof. M. Kadri added to your balance if it lands heads-up. For example, if the quarter lands heads-up 25 cents is added to your balance. Nothing is added to your balance for coins that land tails-up. The game is over when your balance reaches one dollar or more. If your balance is exactly one dollar, you win the game. You lose if your balance exceeds one dollar
