Learning Profile for Assignment #1, And Question #5
Name: Mo Khan
Student ID: 3431709
1. Problem Statement:
Solve the following problem using a program:
Suppose you save $100 each month into a savings account with an annual interest rate of 5%.
Thus, the monthly interest rate is 0.05/12 = 0.00417.
After the first month, the value in the account becomes 100 * (1 + 0.00417) = 100.417
After the second month, the value in the account becomes (100 + 100.417) * (1 + 0.00417) = 201.252
And after the third month, the value in the account becomes (100 + 201.252) * (1 + 0.00417) = 302.507
... and so on.
Write a program that randomly generates monthly savings amounts for the 15 runners in Problem 4.
Each monthly saving should be in the range of $100 to $800.
Extend the AddressBook class to store the monthly savings generated by the random number generator.
Then, display the final account value for each of the 15 runners.
2. Description of the Code:
I created a constructor overload that accepts the `monthlyContribution`
as a parameter. This made it easier to write unit tests rather than
depend on random monthlyContributions. The constructor that accepts a
`firstName` and `lastName` will generate a random `monthlyContribution`
and chain to the overloaded constructor.
I had no idea what `d1` and `d2` means, so I didn't use those
parameters.
I designed this class so that you could predict the future value for `n`
months from now. I did assign the `accountValue` to a prediction of 12
months from now. I would have preferred to implement an interface that
didn't require private instance variables and rather depend on
calculations on the fly but I did my best to bride the requirements with
my own preferences.
