Result:

Your job is to write a program that will help us keep track of the donations to these candidates. You will assume that the program is written for this election where Anders and Valerie are running. It is OK to hard code these into your program. Don't worry about case sensitivity of names Here are the features of the program Feature #1: Contribute to a Campaign [60 points] When someone wants to make a contribution we use this feature to enter the contribution information to the system. Program asks for which candidate the contribution is, and the amount of the contribution, along with the name of the person making the contribution To make things easier for you - You may assume that the name of the donor is just the last name. No spaces allowed in the last name and assume that no two donors will ever have the same last name.:-) According to US laws, no individual is allowed to make political contributions exceeding $2700 per election. The program should not accept the contribution if the total amount of contribution of that individual (go by last name) exceeds $2700 [50 points] The candidate that will be entered by the user will always be either Anders or Valerie -you do not need to error check for this The program supports up to 1000 donations. Feature #2: Report per Candidate a) Displays how many contributions are in the system for each candidate. [30 points] b) The total amount contributed for each candidate. [30 points] c) The average contribution amount for each candidate. This is basically the number you found for a) divided by the number you reported for b) for each candidate. [30 points] File I/O [60 points]: Make sure that you have file l/O in place so we do not loose information when we close the program Classes [40 points]: Make sure that you are using a class representing a donation Election Contributions v1.0 Anders vs. Valerie 1- Contribute to a Campaign 2- Report per Candidate 0- Exit Make a choice (1-3): 1 Candidate (Anders or Valerie): Anders Donation Amount: 1300 Your Name: Jackson Election Contributions v1.0 Anders vs. Valerie 1- Contribute to a Campaign 2- Report per Candidate 0- Exit Make a choice (1-3): 1 Candidate (Anders or Valerie): Anders Donation Amount: 1500 Your Name: Jackson You cannot exceed $2700 per election Election Contributions v1.0 Anders vs. Valerie 1- Contribute to a Campaign 2- Report per Candidate 0- Exit Make a choice (1-3): 2 Anders Total: $1300 # of Donations: 1 lvg.
