Question

1. All members may be public for this example
2. You will need three data members:
a. An array of 3 doubles to keep the votes

b. An array of 3 strings to place the candidates names

c. An array of 3 doubles to place the calculates vote breakdown

3. You will need three methods:
a. A constructor that receives three strings and sets the names of the candidates to these strings and set all the votes initially to zero.
b. A "calcPercentages" method that has no arguments or return values and simply calculates each vote percentage as one vote count divided by the sum times 100
c. A "display Results" method that has no arguments and displays each candidate's names and vote percentage.

****This requires some effort so please drop a like if you are satisfied with the solution****

I have satisfied all the requirements of the question and I'm providing the screenshots of code and output for your reference...

Code:

#include <iostream> //for cout
#include <string> //for string
#include <stdlib.h> //for rand, srand
#include <time.h> //for time
using namespace std;
class CElection
{
public:
    double votes[3];
    string candidateNames[3];
    double votePercentages[3];
    CElection(string candidate1,string candidate2,string candidate3){
        this->candidateNames[0]=candidate1;
        this->candidateNames[1]=candidate2;
        this->candidateNames[2]=candidate3;
        for(int i=0;i<3;i++)
            this->votes[i]=0;
   }
void calcPercentages(){
   double sum=0;
   for(int i=0;i<3;i++)
       sum+=this->votes[i];
   for(int i=0;i<3;i++)
       this->votePercentages[i]=(this->votes[i]/sum)*100;
   }
   void displayResults(){
       for(int i=0;i<3;i++)
           cout<<"\n"<<candidateNames[i]<<" "<<votePercentages[i];
   }
};
//DO NOT EDIT ANY CODE BELOW THIS LINE!
int main(void)
{
//Instantiate a CElection object with three names:
CElection TOOP("Alice","Bob","Other");
//First display a hello message
cout << "\n\n* Welcome to Decision 2019 *\n";
//Randomize the PRN
srand(time(NULL));
int vote;
for (int i=1;i<=10000;i++)
{
vote = rand()%5;
switch (vote)
{
case 0:
case 1:
TOOP.votes[0]++;
break;
case 2:
case 3:
TOOP.votes[1]++;
break;
case 4:
TOOP.votes[2]++;
}
}
TOOP.calcPercentages();
TOOP.displayResults();
}
