Question

Write a program that allows the user to enter the last names of five candidates in a local election and the number of votes received by each candidate. The program should then output each candidate's name, the number of votes received, and the percentage of the total votes received by the candidate. Your program should also output the winner of the election. A sample output is:

Candidate            Votes Received                Percent of Total Votes
Jack                              52                                          26
Jill                                 41                                         20.5
Bob                             13                                          6.5
Bill                              74                                          37
Sam                            20                                          10
Total                                200

The election winner is Bill.
