Overview

The rate at which something grows along with the amount of time the growth is allowed to continue has a significant impact on the final result. A classic demonstration of exponential growth outpacing linear growth can be observed in the output produced by the solution to this laboratory assignment.

Details

Suppose you have a wealthy uncle who gives you two options for your inheritance. He will add to your inheritance every week until he dies according to one of two schemes:

  1. Starting with a given amount (such as $5000), he will add that amount to your total inheritance every week, or
  2. Starting with one penny, he will double your inheritance every week.

Option 2 will always outpace option 1 at some point in the future, but the question is when will option 2 be a better financial decision for you than option 1 and will it happen before your uncle dies?

For this lab you will be creating a game that explains the options briefly and allows a user to pick option 1 or option 2. For your game, you must use your creativity to describe a different scenario (not your uncle dying) to motivate the two options and the corresponding output. The starting amount for option 1 should be randomly generated (such as between 0 and 5000) each time the user runs the game. Also, the number of remaining weeks of life for your uncle (or whatever fits your scenario) should be randomly generated (such as between 0 and 40 weeks).

You should display the value of the inheritance for each option, each week until either:

  1. Option 2 exceeds option 1, or
  2. Your uncle dies

You should tell the user whether they "won" or not and how much they won or lost. They win if they chose the option that causes them to end up with more money. They lose if they chose the option that leaves them with less money. The amount won or lost is based on the total number of weeks before your uncle dies, not the number of weeks that are displayed. For instance, in the example program run below, the amount the user missed out on is $21,404,654.73 (the difference between linear and exponential at 32 weeks) not $31,249.77 (the difference between linear and exponential for the last week displayed (week 24)).

Lastly, you should give the user the option of playing the game again every time they see their results.

Here is an example run of the program:
