## Introduction: Programmers for a Better Tomorrow

Programmers for a Better Tomorrow is an organization dedicated to helping charities, medical
societies, and scholarship organizations manage various tasks so that they can focus on making
the world a better place! They have asked you and your classmates to help them develop some
new programs to benefit their organizations.

## Problem: Scholarship Endowment Fund Part 2 (fund2.c)

One division of Programmers for a Better Tomorrow is their Scholarship Endowment Fund. They
provide yearly scholarships to students who need a hand in amounts of 1000, 500, and 250
dollars.

The money for these scholarships comes from interest made on previous donations and
investments. You will create a program to track the amount in the Fund as various donations
and investments are made. Donations are a one-time increase to the amount. Investments are
listed as one-time decreases with the return on investment (ROI) being calculated at a later
time. ROI is not within the scope of this assignment.
To begin the program, ask the user for the starting balance of the fund.

## Then, your program should allow the user the following options:

1) Make a donation
2) Make an investment
3) Print balance of fund
4) Quit

Option 1:
Prompt the user for their donation amount. Add this amount to the balance of the fund.
Option 2:
Prompt the user for their investment amount. In order to continue to provide scholarships, the
fund cannot be allowed to fall below its initial amount. If an investment would bring the fund
below that value, then simply print out “You cannot make an investment of that amount.” If
the amount is valid, deduct it from the balance of the fund.
Option 3:
Print the current balance of the fund, the current total number of donations, and the current
total number of investments.
2

After options 1, 2, and 3 prompt the user with the menu again.
Option 4:
Print the final balance of the fund, the final total number of donations, and the final total
number of investments.

## Input Specification

1. Menu responses are guaranteed to be integers greater than zero
2. Each monetary value will be a numerical value between -20,000 and 20,000.

## Output Specification

Any monetary values should be formatted to two decimal places.

## Output Sample

Below is a sample output of running the program. Note that this sample is NOT a
comprehensive test. You should test your program with different data than is shown here based
on the specifications given above.

In the sample run below, for clarity and ease of reading, the user input is given in italics while
the program output is in bold. (Note: When you actually run your program no bold or italics
should appear at all. These are simply used in this description for clarity’s sake.)
