Question

Write a program that scores a blackjack hand. In blackjack, a player receives from two to five
cards. (The player decides how many, but that has no effect on this exercise.) The cards 2
through 10 are scored as 2 through 10 points each. The face cards, jack, queen, and king are
scored as 10 points. The goal is to come as close to a score of 21 as possible without going
over 21. Hence, any score over 21 is called "busted." The ace can count as either 1 or 11,
whichever is better for the user. For example, an ace and a 10 can be scored as either 11 or
21. Since 21 is a better score, this hand is scored as 21. An ace and two 8' s can be scored as
either 17 or 27. Since 27 is a "busted" score, this hand is scored as 17.
The user is asked how many cards she or he has, and the user responds with one of the
integers 2, 3, 4, or 5. The user is then asked for the card values.
Card values are 2 through 10, jack, queen, king, and ace. A good way to handle input is to
use the type char so that the card input 2, for example, is read as the character '2', rather than
as the number 2. Input the values 2 through 9 as the characters '2' through '9'. Input the values
10, jack, queen, king, and ace as the characters 't ', 'j', 'q', 'k', and 'a'. An ace can also be
entered as a '1'. (Of course, the user does not type in the single quotes.) Be sure to allow
upper as well as lowercase letters as input.
After reading in the values, the program should convert them from character values to
numeric card scores, taking special care for aces. The output is either a number between 2
and 21 (inclusive) or the word Busted. Use functions where appropriate. Use a switch
statement to determine the correct value for a card. Your program should include a loop that
lets the user repeat this calculation until the user says she or he is done.

Explanation / Answer

#include using namespace std; void instructions ( ); void input (int& number_of_cards, char& card_value1, char& card_value2, char& card_value3, char& card_value4, char& card_value5); int calculate_hand (int& number_of_cards, char& card_value1, char& card_value2, char& card_value3, char& card_value4, char& card_value5); void output_result ( ); int main ( ) { char yes; int number_of_cards; char card_value1; char card_value2; char card_value3; char card_value4; char card_value5; instructions ( ); do{ input (number_of_cards, card_value1, card_value2, card_value3, card_value4, card_value5); cout
