Assignment 9

due Tuesday 5 April at 01:00 AM

In the game of blackjack, the cards 2 through 10 are counted at their face values, regardless of suit, all face cards (jack, queen, and king) are counted as 10, and an ace is counted either as a 1 or an 11, depending on the total count of all the cards in a player's hand.

The ace is counted as 11 only if the total value of all cards in a player's hand does not exceed 21, else it is counted as a 1.

Using this information, write a C program that uses a random number generator to select three cards (a 1 initially corresponding to an ace, a 2 corresponding to a face card of two, and so on), calculate the total value of the hand appropriately, and display the value of the three cards with a printed message. 

Welcome to Blackjack!
