#include <iostream>
#include <iomanip>
using namespace std;

int main()
{
string *names;
double *votes;
double sum=0;
double winner=-1;
string winnerName="";
int total=0;
int size;
cout<<"Enter the number of candiates: ";
cin>>size;
names=new string[size];
votes=new double[size];
//reading votes
for(int i=0;i<size;i++){
cout<<"Enter candidate's name :";
cin>>names[i];
  
cout<<"Enter votes received :";
cin>>votes[i];
sum+=votes[i];
//finding the winner
if(winner<votes[i]){
winner=votes[i];
winnerName=names[i];
}
}
  
cout<<endl;
//printing the data
cout << setprecision(2)<<fixed;

cout<<setw(20) << left <<"Name"<<setw(20) << left <<"Votes"<<setw(20) << left <<"Percentage"<<endl;
for(int i=0;i<5;i++){
cout<<setw(20) << left<<names[i]<<setw(20) << left <<votes[i]<<votes[i]/sum*100<<"%"<<endl;
total+=votes[i];
  
}
cout<<setw(20) << left<<"Total"<<setw(20) << left <<total<<endl;
cout<<"The Winner of the Election is "<<winnerName;
  
return 0;
}
