Question

C++, using Visual Studio

Redo program using dynamic arrays. You must ask the user for the number of candidates and then create the appropriate arrays to hold the data.

//header//
#include <iostream>
#include <iomanip>
#include <string>

using namespace std;
//function declaration//
int voteamount(int list[], int size);
int wintally(int list[], int size);
//main start//
int main()
{
    //variables//
    string candidates[5];
    int votes[5] = {0};
    int totalVotes;
    int i;
    cout << fixed << showpoint;
    //decimal precision//
    cout << setprecision(2);
    cout << "Enter candidate's name and the votes received by "
         <<"the candidate." << endl;

    for (i = 0; i < 5; i++)
        //user input candidates//
        cin >> candidates[i] >> votes[i];
    //calculate sum of votes//
    totalVotes = voteamount(votes, 5);
    //print votes received//
    cout << "Candidate    Votes Received   % of Total Votes" << endl;
    for (i = 0; i < 5; i++)
        cout << left << setw(10) << candidates[i]
             << right << " " << setw(10) << votes[i] << "   " << setw(15)
             << (static_cast<double>(votes[i]) / static_cast<double>(totalVotes)) * 100
             << endl;
    cout << "Total            " << totalVotes << endl;
    cout << "The Winner of the Election is "
         << candidates[wintally(votes, 5)]
         << "." << endl;
   system("PAUSE");
    return 0;
}
//method for vote amount//
int voteamount(int list[], int size)
{
   int sum = 0;
   for (int i = 0; i < size; i++)
        //calculates the sum of votes//
       sum = sum + list[i];
    //returns the value//
   return sum;
}
//method for winner tally//
int wintally(int list[], int size)
{
    int winInd = 0;

    for (int i = 0; i < size; i++)
        //checks list with the index value//
        if (list[i] > list[winInd])
            winInd = i;
    return winInd;
}

Explanation / Answer

#include #include #include #include #include using namespace std; int main() { //variable declarations. //NOTE: pointer variables are declared later ofstream outfile; int array_size; double next, winner_votes(0), sum(0), percent; string candidate, winner_name; outfile.setf(ios::fixed); outfile.setf(ios::showpoint); outfile.precision(2); cout.setf(ios::fixed); cout.setf(ios::showpoint); cout.precision(2); //opens output file outfile.open("results.txt"); if(outfile.fail()) { cout next; votes[i] = next; sum = sum + next; if(next > winner_votes) { winner_votes = next; winner_name = candidate; } } cout
