In this lab, you will start the process of building a blackjack game. In order to complete this task, you must make the following modifications to our Hand class:
Put the Hand class in its own file called "Hand.h". Remember to include #ifndef blocks!
Add the following public functions to the hand class:
void addCardToHand – adds a new card to the player's hand
int getHandValue – returns the total value of the player's hand. This is used to determine whether or not the player has busted.
Once you implement these functions, you are ready to implement the game logic:
Begin by dealing the player 2 starting cards.
Until the player no longer wants any more cards OR the player has busted (gone over 21):
Deal the player a new card. Add this card to the player's current hand.

In this lab, you will complete the game of blackjack that we started in Lab 3. Note that this lab does not require you to use classes, but it would be a very good idea as it will help when implementing PA2. Here's the complete flow of the game:
Program Start
Output an introduction
Starting with the player, do the following
Deal the player a card.
Add the card's value to the player's total hand.
Output the value of the card just dealt and the player's current hand total (score)
Ask the player if he would like to hit or stand
If the player hits, go back to #1
After the player busts (goes over 21) or stands
If the player has not busted, begin computer's play
Deal the computer a card
Add the value of the card to the computer's hand total (score)
If a card causes the computer to bust (go over 21), output a message. Go to step #7.
If the computer's hand total is less than 17, it must take another card (hit). Go to step #2.
If the computer's hand is 17 or more, the computer stands.
Stop computer play
When both player and computer are done
If the player has not busted (gone over 21) and the computer busted, the player wins
If the player has not busted, the computer has not busted, and the player's hand total is greater than the computer, then the player wins
If the player has not busted, the computer has not busted, and the player's hand total is less than the computer's then the computer wins
If the player has busted, then the computer wins.
