Question

Program 1: Blackjack

Part of the card game Blackjack involves dealing two cards from a shuffled deck of cards; to each of the players. (There’s more to it than that, but we’ll start with this).

Create a function that returns a string representing a randomly chosen card, for example, “6 of Clubs” or “King of Hearts”.

Your program should ask how many players there are. Then, it should use the function to “deal” two random cards to each player. Print the cards each player gets on the screen.

Extra question there’s more work to do before this program will play a game with you. Think about what you would need to do to turn this into a program that can play Blackjack.

Program 2:

Rock, Paper, Scissor Game

Write a program that lets the user play the game of Rock,Paper, Scissors against the computer.

The program should work as follows.

1. When the program begins, a random integer number in therange of 1 through 3 is generated. If

the number is 1, then the computer has chosen rock. If thenumber is 2, then the computer has

chosen paper. If the number is 3, then the computer has chosenscissors. (Don’t display the

computer’s choice yet)

2. The user enters his or her choice of “rock”,“paper”, or “scissors” at the keyboard.(You can use a

menu if you prefer)

3. The computer’s choice is displayed.

4. A winner is selected according to the followingrules:

If one player chooses rock and the other player choosesscissors, then rock wins.

If one player chooses scissors and the other player choosespaper, then scissors wins.

If one player chooses paper and the other player chooses rock,then paper wins.

If both players make the same choice, the game must be playedagain to determine the winner
