18. Function Description System Main Function
The main function will carry out the execution of the project files.
The different functions will be integrated in conformity with the BlackJack Game rules. The main function:
1. Initializing and starting new game.

The shuffling process is displayed during which the following takes place:
1. An array of numbers p=[1,2,3,...51,52] is generated.
2. Mixing the cards r times (r=Randomize()+16) using ACUAS instruction RANDOM(0,51) at least 16 times.
3. A control subroutine checks whether already dealt cards are not generated again.
4. A progress bar is displayed to simulate the shuffling progress.

20. Function Description Player Hand Function
It processes, executes and displays the Player's play.

- calculates the Player's hand points
- displays the Player's play and result
- checks if the Player busts
- checks the number of cards condition
- checks the BlackJack condition

The TakeCard() function represents the dealing process. It proceeds as following:
1. The pack is shuffled.

It calculates the points of the Player's hand.
This function will calculate how much in points the Player's hand is. It does that by the following steps:
1. Each card in the pack has been indexed. The card index is represented by the variable uint8_t CardID.
2. From the card index the integer value Number=((CardID-1)/4)+1 is calculated from which the CardValue is deduced.
3. PlayerPoints is calculated Pp+=CardValueAccording to the value of Pp, the ace value is determined.
PAce11=0 => Ace equals 1
PAce11=1 => Ace equals 11

24. Function Description DealerHand Function
It processes, executes and displays the Dealer's play
It takes Player BlackJack flag as input and does the following:
resets the Dealer points
as long as Dp<17:

This function will calculate how much points the Dealer has. It does that by the following steps:
- Each card in the pack has been indexed. The card index is represented by the variable uint8_t CardID.
- From the card index the integer value Number=((CardID-1)/4)+1 is calculated from which the CardValue is deduced.
- DealerPoints is calculated Dp+=CardValue
According to the value of Dp, the ace value is determined.
DAce11=0 => Ace equals 1
DAce11=1 => Ace equals 11
