C++ Blackjack Example

I created a simple blackjack example using C++ that allows the player to play against a CPU opponent and whoever gets closest to 21 without going over wins. This is a simple blackjack example because players only have the option to hit or stay each turn.

//Specification: This program plays a version of

//the card game of 21.

//A human player is pitted against the computer.

//The player who is the closest to 21 without

//going over wins the hand.

play21(void);

dealCards(int, string);

main(){

char keepPlaying = 'n'; //loop control variable

do {

play21();

//keep playing?

cout <<

'Do you want to play another hand (y/n)?';

cin >> keepPlaying;

}

while(keepPlaying 'Y' keepPlaying 'y');

}

void

play21(void){//play one hand of 21//randomize the cards

srand((

int) time(0));// deal the cardsint person = dealCards(2, 'Your Cards:');

cout <<

' = ' << person << endl;int house = dealCards(2, 'Computers Cards:');

cout <<

' = ' << house << endl;// Ask if human wants a hit

hit(person);

cout << endl;

//Determine if computer takes a hitwhile ((house < person) && (house <= 21) && (person <= 21)) {

house += dealCards(1,

'The Computer takes a card ');

cout << endl;

}

//show who won....

determineWinner(person, house);

}

void

determineWinner(int humanScore, int houseScore) {//compare the scores to see who won//Both the human and the house score totals are provided as arguments//Display total scores and indicate winner//possible outcomes: human wins, computer wins, tie//display the scores

Now I’d like to share one of my experience of programming C. Our teacher gave us a task: to finish a small but not so useless program by our own in C.
