Question

Please code in C# (C-Sharp)

Assignment Description

A pirate needs to do some accounting and has asked for your help. Write a program that will accept a

pirate’s starting amount of treasure in number of gold pieces. The program will then run one of two

simulations, indicated by the user:

1) The first simulation runs indefinitely, until one of two conditions is met: the pirate’s treasure

falls to 0 or below, or the pirate’s treasure grows to 1000 or above.

2) The second simulation runs for a number of years set by the user.

For both simulations, each year the pirate has an equal chance to either gain or lose 50 gold pieces. At

the end of each year, the pirate’s total gold and the year is displayed to the user. Validate all user input.

Tasks

1) The program needs to contain the following

a.

A comment header containing your name and a brief description of the program

b. At least 5 comments besides the comment header throughout your code

c.

A prompt for the starting treasure amount

d. A prompt to choose a simulation

i. The first simulation continues until the treasure amount becomes 1000 or more

or 0 or less

ii. The second simulation will prompt the user for number of years, then simulate

that many years. The gold amount can go below zero

e. For both simulations, treasure amount has an equal chance to increase by 50 or

decrease by 50 each year

f.

Output the year and treasure amount after each year

g.

“Press enter to continue” and Console.ReadLine(); at the end of your code

h. Validate all user input. Either through exception handling or boolean logic.

2) Upload a completed .cs file onto the Assignment 5 submission folder and a word document

containing the following six (6) screenshots:

a.

One run of the first simulation, starting amount 500

i. Your screenshot only needs to show up to the last 10 years

b. Two runs of the second simulation, starting amount 300 for 10 years and starting

amount 500 for 20 years

c.

Three test runs with invalid input for the following: starting treasure amount, simulation

choice, number of years
