How to differentiate scores between names using functions - c++

Question

I am trying to make a talent show type voting program using functions.
I have the majority of it figured out. The program prompts you to enter a name, followed by five scores, if you type "Done" rather than a name, it will close. I'm using functions for a majority of the code to practice with them.
My big issue is that there could be an infinite amount of names (as many as the user enters) and I am unaware on how to add up all 5 scores per name, I do not know how to differentiate between them. The 5 scores will be averaged and the person with the highest average of (3 scores, dropping 2) will be the winner.
Side Note: I need to drop the highest and lowest score of each person, I believe I could figure it out but an example with a function of this would be helpful to someone who is new to them.
I've researched this a lot but I could not find any examples that are similar enough to mine (having a possibly infinite amount of contestants.)
Here is my code so far, the function at the bottom is me messing around with functions to get a hang of them and see if i can get any sums of scores from a name.
#include <iostream>
#include <string>
using namespace std;
void validCheck();
void calcAvgScore();
void findHigh();
void findLow();
int main(){
int judge = 1;
double score = 0;
string name;
while (name != "done" || name != "Done"){
cout << "Enter Contestant Name, if no more, type 'done': ";
cin >> name;
if (name == "done" || name == "Done"){ break; }
for (judge = 1; judge < 6; judge++){
cout << "Enter score " << judge << " ";
validCheck();
}
}
system("pause");
return 0;
}
void validCheck(){
double score;
cin >> score;
if (score < 1 || score > 10){
cout << "Please Enter a score between 1 and 10: ";
cin >> score;
}
}
void calcAvgCheck(){
double score = 0, value = 0;
static int average;
score += value
}

Answer 1

Declare a string "winner", double "win_avg", double "avg" outside the while loop.
Have your validCheck() return the double value given as input (named score).
Declare a double array before your for loop (double[5] scores). Store each value returned from validCheck() into the array).
Call std::sort(std::begin(scores), std::end(scores)) to sort your scores ascending. Find the average (ignoring the max and min), and hold the max average as well as the names of the person with the max average.
#include <algorithm> // std::sort
...
double validCheck();
...
int main(){
string name;
string winner;
double win_avg;
double avg;
while (name != "done" || name != "Done"){
cout << "Enter Contestant Name, if no more, type 'done': ";
cin >> name;
double scores[5];
if (name == "done" || name == "Done"){ break; }
for (int judge = 0; judge < 5; ++judge){
cout << "Enter score " << judge << " ";
scores[judge] = validCheck();
}
std::sort(std::begin(scores), std::end(scores));
for(int score = 1; score < 4; ++score)
avg += scores[score];
avg /= 3;
if(avg > win_avg) {
winner = name;
win_avg = avg;
}
avg = 0;
}
std::cout << "Winner is: " << winner << "\n";
}
double validCheck(){
double score;
cin >> score;
if (score < 1 || score > 10){
cout << "Please Enter a score between 1 and 10: ";
cin >> score;
}
return score;
}
If you want to find the average in a function and return the value you can do this
double calcAvgCheck(const double& scores[5]) {
double avg = 0.0;
for(int score = 1; score < 4; ++score)
avg += scores[score];
avg /= 3;
return avg;
}
