BlackJack:
This game is played between a player and a dealer. (In this exercise there is only one player - you.)
Each person (player, dealer) draws two cards with each card's face counting towards a player's score. Picture cards: Jack, queen, and king count 10. Other cards count whatever number displays.
The object of the game is to get as close to 21 points as possible without goving over 21. (Going over 21 points is called 'BUSTING'.) The first one to bust looses that hand. 21 is the best score.
After looking at your initial 2 cards, you can choose to improve your score by taking an additional card. This is known as "taking a hit". That card is added to your total. Most players have a hidden rule that they go by, such as "I must take a hit on 17 or under." You can take hits repeatedly until you bust, or get close enough to 21.
Once the player Stops taking hits, the dealer can take a series of hits. If the dealer busts, you win. If not, you compare scores and the highest score wins.
To make this 'game' easier to program, here are a few simplying rules for our simulation:
1.) Assume an endless deck - don't worry about 52 cards or the same card being drawn twice.
2.) An ACE always has a value of 1 (one) rather 1 or 11.
3.) Don't worry about double downs or blackjack.
4.) Delaer must hit at 16 or under.
5.) Dealer can't hit at 17 or over.
6.) Player is prompted for the number that is their limit.
7.) Nobody wins ties.
8.) Keep a running total of the player's socre and the dealer's socre.
You Must Plan It out on Paper First !! This is the deliverable for project 1.
Some ideas for functions and procedures:
RANDOM function or package - picks a random number --- 2 examples are given to you
PX procedure - prints stars for separation
PL procedure - to save typing DBMS_OUTPUT.PUT_LINE
GET_SUIT function - Use a random number from 1 - 4 to return one of four suits ('Hearts', 'Clubs', etc..)
GET_CARD_NAME function - turns a 1 into an ACE, a 2 into TWO, 11 into Jack, 12 into Queen, etc..
NORMALIZE function - to convert jacks, queens, and Kings into a value of ten
DRAW procedure - used by a player or dealer to draw a card
CHECK_BUSTED function - see if anyone has a score over 21
