This assignment is a review of loops. Do not use anything more advanced than a loop, such as programmer-defined functions or arrays or classes.
If you know blackjack, you may be tempted to change the specifications below to make the game more "blackjack-like". Please don't. Be sure to follow these specs exactly and don't try to improve on them. You will be penalized if the specs are not met exactly.
In the card game named 'blackjack' players get two cards to start with, and then they are asked whether or not they want more cards. Players can continue to take as many cards as they like. Their goal is to get as close as possible to a total of 21 without going over. Face cards have a value of 10.
Write a command line game that plays a simple version of blackjack. The program should generate a random number between 1 and 10 each time the player gets a card. Each of the values (1 through 10) must be equally likely. (In other words, this won't be like real black jack where getting a 10 is more likely than getting some other value, because in real black jack all face cards count as 10.) It should keep a running total of the player's cards, and ask the player whether or not it should deal another card. If the player hits 21 exactly, the program should print "Congratulations!" and then ask if the player wants to play again. If the player exceeds 21, the program should print "Bust." and then ask if the player wants to play again. Sample output for the game is provided below. Your program should produce the same output.
If you'd like a little refresher on random number generation, see lesson 7.3.
In order to make your code pass the zyBooks tests, you will need to comment out the line where you seed the random number generator (using srand()).
First cards: 3, 2 Total: 5 Do you want another card (y/n)? y Card: 6 Total: 11 Do you want another card (y/n)? y Card: 7 Total: 18 Do you want another card (y/n)? n Would you like to play again (y/n)? y First cards: 10, 2 Total: 12 Do you want another card (y/n)? y Card: 6 Total: 18 Do you want another card (y/n)? y Card: 7 Total: 25 Bust. Would you like to play again (y/n)? n
Be sure to use iterative development. Start with a small amount of functionality, and then grow it gradually. This way you can compile and run your program after each statement that you write.
You might start by just generating a single card. The program execution might look like this:
First card: 3
Then generate two cards
First cards: 3, 2
Next add a variable to store the total, and a statement to show its value:
First cards: 3, 2 Total: 5
Next read in a user response and print out the value that was entered
First cards: 3, 2 Total: 5 Do you want another card (y/n)? y You entered: y
Next you might add a loop, without yet adding the blackjack logic
First cards: 3, 2 Total: 5 Do you want another card (y/n)? y Do you want another card (y/n)? y Do you want another card (y/n)? n
Now move the display of the total to the loop
First cards: 3, 2 Total: 5 Do you want another card (y/n)? y Total: 5 Do you want another card (y/n)? y Total: 5 Do you want another card (y/n)? n
Your next steps might be something like this:
In order to get full credit for this assignment, your code will need to be well-structured. For example, in well-structured code, output such as "Congratulations!", "Bust.", and "Would you like to play again (y/n)?" will only occur once. (The question "Do you want another card?" may occur twice if you need it to prime a loop.) Also, the statements to output the result of a game ("Congratulations!" or "Bust.") should not occur inside the game-playing loop, because it is code that is only executed once, after the game has ended.
