Question

(Write a program for C++ )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

Analyze and design this program. Implement the design. Compile and test the program. Submit your analysis and design document, and your source code.

Answer 1

#include <cstdlib>
#include <iostream>

using namespace std;

int main()
{
   string array1[5];
   int votes[5];
   int i;
   float total=0.0;
   for(i=0;i<5;i++)
   {
   cout<<"enter last name"<<endl;
   cin>>array1[i];
                cout<<"enter votes received"<<endl;
                   cin>>votes[i];
      total=total+votes[i];          
   }

cout<<total;

cout<<"Result"<<endl;
cout<<"Candidate"<<" Votes Received % of Total Votes"<<endl;
    for(i=0;i<5;i++)
   {
   cout<<array1[i]<<"           "<<votes[i]<<"                "<<(float)(votes[i]/total)*100.0<<endl;
          
   }
  
    system("PAUSE");
    return EXIT_SUCCESS;
}
