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	% of Total Votes
Johnson	5000	25.91
Miller	4000	20.73
Duffy	6000	31.09
Robinson	2500	12.95
Ashtony	1800	9.33
Total	19300

The Winner of the Election is Duffy.

Algorithm

// sore the maximum no of votes

for i = 1 to 5

BEGIN

            str = ask user to enter name

            // add values into array

            name.add(str)

            votes.add(v)

            total_votes += v

            // update the max votes

            if v > max

            BEGIN

            END

END

for i = 1 to 5

BEGIN

            // calculate the percentage of votes of current candidate

            Per = votes[i] / total_votes * 100.0

            print(name[i], votes[i], per)

END

For I = 1 to 5

BEGIN

            If votes[i] == max

            BEGIN
