Ok, i have been working on this program for a LONG time and i need some major help with the main.cpp file PLEASE.
I have to design a function that Designs and implements a function void getJudgeData() that asks the user for a judge's score, stores it in a reference parameter variable, and validates it. This function should be called by your function main() once for each of the 5 judges.

I dont get the reference parameter... Could anyone please please help me out i turned in the .cpp and .h files already and he said to not modify it anymore that it is good. To only work on the main.cpp and i need major help with the void getJudgeData part.


Main.cpp file

#include <iostream>
#include "Stat.h"

using namespace std;

void getJudgeData();
double calcScore();


int main()
{
    Stat s;

	cout << "This program assignment number 4 was created by Jeremy Rice" << endl;
	cout<<  "The Next American Idol!!!"<<endl;
    cout<< "Please enter your scores below!"<<endl; 

// asking for the scores from each judge
//using the function getJudgeData
cout<<"Judge #1 ";
getJudgeData();
cout<<"Judge #2 ";
getJudgeData();
cout<<"Judge #3 ";
getJudgeData();
cout<<"Judge #4 ";
getJudgeData();
cout<<"Judge #5 ";
getJudgeData();


system("pause");
	return 0;
}

void getJudgeData()
{
     Stat s;
    s.getNum("Please enter your score ");
  
 
}

double calcScore()
{
       Stat s;
       s.getAverage= (s.getSum - s.getMin - s.getMax)/3;
}

the idol.cpp file

#include <iostream> // for cin, cout
#include "Stat.h"

using namespace std;

Stat::Stat(  ){
    reset( );
}

void Stat::setNum ( int newNum ){
    thenum = newNum;
//  update data members
    if( count==0 ) // first integer entered
        min = max = thenum;
    count++;
    sum  = sum+thenum;
    prod = prod*thenum;
    if( thenum<min )
        min = thenum;
    if( thenum>max )
        max = thenum;
    if( thenum%2==0 )
        evens++;
    else
        odds++;
}

void Stat::getNum ( string prompt ){
    int someInt;
    cout << prompt;
    cin  >> someInt;
    setNum( someInt );
}

void Stat::reset (  ){
    count = 0;
    sum   = 0;
    prod  = 1;
    evens = 0;
    odds  = 0;
}

int Stat::getNum (  ){
    return thenum;
}

unsigned Stat::getCount (  ){
    return count;
}

int Stat::getSum (  ){
    return sum;
}

long Stat::getProd (  ){
    return prod;
}

int Stat::getMin (  ){
    return min;
}

int Stat::getMax (  ){
    return max;
}

float Stat::getAverage (  ){
    return (1.0 * sum) / count;
}

unsigned Stat::getEvens (  ){
    return evens;
}

unsigned Stat::getOdds (  ){
    return odds;
}

and the header file

— the core problems are: getJudgeData creates its own Stat (so scores never accumulate in main) and calcScore tries to assign to the member accessor instead of computing with the Stat already filled in. was right to suggest using a score variable passed by reference and declaring the Stat in main; below is a compact, safe way to do that and to compute the average after dropping highest and lowest.

// add at top of main.cpp
#include <limits>

void getJudgeData(int &score);
double calcScore(const Stat &s);

// read five validated scores into the Stat in main
int main() {
    Stat s;
    int score;
    for (int i = 1; i <= 5; ++i) {
        cout << "Judge #" << i << " ";
        getJudgeData(score);   // fills score by reference
        s.setNum(score);       // commit the validated score to Stat
    }
    cout << "Final score (drop high/low): " << calcScore(s) << endl;
    return 0;
}

void getJudgeData(int &score) {
    while (true) {
        cout << "Please enter score (0-10): ";
        if (!(cin >> score)) {
            cin.clear();
            cin.ignore(numeric_limits<streamsize>::max(), '\n');
            cout << "Invalid input. Enter an integer." << endl;
            continue;
        }
        if (score < 0 || score > 10) {
            cout << "Score must be 0..10. Try again." << endl;
            continue;
        }
        break;
    }
}

double calcScore(const Stat &s) {
    if (s.getCount() < 3) return 0.0; // safety
    double middleSum = s.getSum() - s.getMin() - s.getMax();
    return middleSum / 3.0;
}

Notes: adjust the 0..10 range if the assignment expects a different one. Do not create a local Stat inside getJudgeData — that prevents main() from seeing values. Use cin.clear()/cin.ignore() to handle non-numeric input. Avoid assigning to getAverage (it's a function); compute with getSum(), getMin(), and getMax() and use 3.0 to force floating-point division.

Good day. A few points for you:
1.You need to declare a score variable and reference that in your function.
2.You need to be declaring a Stat in your main.
3.You will need a loop that will repeat your main untill a 'y' is entered in the final user input(cin).
