Question

"Gambling Greg" Assignment

Outcomes:

• Demonstrate the ability to create and use structs
• Demonstrate the ability to create and use menus
• Demonstrate the ability to create and use an array of structs
• Demonstrate the ability to generate and use random numbers

Program Specifications:

Assume that gambling Greg often goes to the Dog Racing Track. Greg loves to bet on the puppies. In each race Greg will place a wager and pick a dog. The dog information will be stored in a structure name DOG as follows:

Name, amount to pay out if Greg wins, and the odds of this dog winning the race.

The program should have the following menu:

[G]amble

[R]esults of All Races

[L]eave the Dog Track

If Greg selects [G] the program will ask Greg for his wager and allow Greg to pick a dog from a list. The program will then run the race. The result will be shown to Greg. The results of the race will be stored for future use.

If Greg selects [R] the program will show Greg the results of all previous races entered during this run of the program.

If Greg selects [L] the program will end.

The dogs:

You will create 9 different dogs. See below:

Dog Name	Payout	Odds of Winning
You name the dogs	2 to 1	40%
	5 to 1	10%
	10 to 1	8%
	15 to 1	6%
	50 to 1	1%
	20 to 1	4%
	10 to 1	8%
	5 to 1	10%
	3 to 1	13%

Submission Requirements:

You must follow the rules from the first assignment. Don't forget your design tool!

DO NOT:

• Use global variables
• Use the goto command
• Use the break command outside a case statement
