New to C++ Looking for help revising a program by using arrays

I'm not expecting anyone to just hand me the answer, but I am looking for some guidance. For my C++ class we wrote a program last week where we had 5 judges each had a score that the user had to put in, then we needed to find the average without the highest and lowest score being used. I did this using loops and a lot of if statements. Now my teacher asked us to go back and use arrays, and said we should be able to just modify the original code a bit, but to now have it so there can be 5 to 20 judges, the user should be able to input that number in. I'm just having a hard time figuring out which spots could be replaced with arrays. I already have it where a person can put in the amount of judges, but I'm not sure how to put that in an array either, so judges is an unused variable at the moment.This is what my code looks like right now. Thanks in advance!

 #include <iostream>

using namespace std;

//Function prototypes

void getJudgeData(double &x);

double findLowest(double ,double ,double ,double,double);

double findHighest(double,double,double,double,double);

void calcAverage(double,double,double,double,double);

double judges;
//Program begins with a main function

int main()

{

//Declare variables

double judgeScore1,judgeScore2,judgeScore3;

double judgeScore4,judgeScore5;

cout<<"Scores given by all five judges: \n\n";

//Function calls to get each judge data
cout<< "How many Judges are there? (Must be 5 to 20): ";
cin>> judges;
while(judges<5||judges>20){
    cout<< "Sorry there must be 5 to 20 judges\n";
    cout<< "How many Judges are there? (Must be 5 to 20): ";
    cin>> judges;

getJudgeData(judgeScore1);

getJudgeData(judgeScore2);

getJudgeData(judgeScore3);

getJudgeData(judgeScore4);

getJudgeData(judgeScore5);

//Function call to obtain average

calcAverage(judgeScore1,judgeScore2,judgeScore3,

judgeScore4,judgeScore5);

//Pause the system for a while



}
