Purpose: Use data types/variables, various selection structures, random number generation, input/output, performing calculations and formatting output.
Description: You have just been given the opportunity to win prizes from a sweepstakes entry you made at the county fair! The opportunity includes winning 4 prizes, each will be determined by a different game of chance. You may create your own descriptions for the prizes and values as you like, just make sure they are patterned as follows. Each of these requires a random number generation.
Flip a coin: Depending upon the heads or tails result, you will get prize1:
Heads: A smartphone charger worth $9.99
Tails: A 9-volt battery and a wire worth $0.49 (the booby prize)
Roll a six-sided die: Depending upon the number that comes up, you will get prize2:
1: A refrigerator magnet worth $1.49
2: A handy grocery bag worth $.59 (the booby prize)
3: A half-price ticket to next year’s fair worth $4.00

Number 14: (Ace): Get $10.00
After counting the number of booby prizes one person may get, use the following scale to award a consolation prize:
1 booby prize: $1.00
2 booby prizes: $2.00
3 booby prizes: $3.00
4 booby prizes: $4.00
As you generate the random numbers (use any method you like), here are suggested variables:
Store the following double values as prize1Value, prize2Value, prize3Value, prize4Value;
Store the following string values as prize1Desc, prize2Desc, prize3Desc, prize4Desc;
Store the following string values as result1Desc, result2Desc, result3Desc, result4Desc;
You should shorten the descriptions when storing them, keeping them to 20 chars or less.
Store the count of booby prizes;
Accumulate the total dollar value of all prizes;
Utilize as many other variables as you like
You can experiment with validation loops (optional).
Generate a report the information with a header and 4 detail lines formatted as such:
Example Output:
