help with program

[LhbM92yv]

I am trying to pull each grade from the void getData() Function but it's only pulling the last grade. I understand that the grades are in a while loop and all but the last grade may not show in the rest of the program... but i was wondering if it was possible for it to print each grade in the void getData Function.
Please and Thank you

#include <iostream>
#include <fstream>
#include <cmath>
#include <iomanip>

using namespace std;

void getData(string fileName, int scores[], int &grade, int &numStudents)
{
ifstream inFile;
inFile.open(fileName.c_str());

string key;
inFile >> key;

scores[11];

for( int i = 0; i<scores[i]; i++)
{
scores[i] = 0;
}

numStudents = 0;
string exam;
while(( inFile >> exam) && exam != "" )
{
numStudents++;
grade = 0;
for( int i = 0; i < 10; ++i )
if( exam[i] == key[i] )
grade++;

cout << "student " << numStudents << " - " << grade << endl;

}
cout << grade ;

}

double average (int scores[], int &grade, int &numStudents)
{
double avg = 0;
double sum = 0;

for (int i = 0; i < numStudents; i++)
{
sum = sum + grade;
}

avg =(sum)/(numStudents);
return avg;
}

int findHighest(int scores[], int grade ,int numStudents)
{
int Highest = 0;

for (int i = 0; i < numStudents; i++)
{
if (scores[grade] > scores[Highest])
Highest = i;
}
return Highest;
}

int findLowest(int scores[], int &grade ,int &numStudents)
{
int Lowest = 0;

for (int i = 0; i < numStudents; i++)
{
if (scores[grade] < scores[Lowest])
Lowest = i;
}
return Lowest;
}

int main()
{
const int MAX = 11;
int scores[MAX];
const string fileName = "grade_data.txt";
int numStudents = 0;
int grade = 0;

getData(fileName,scores, grade, numStudents);

int highest = findHighest(scores, grade, numStudents);
cout << "high score - " << highest << endl;

int lowest = findLowest(scores, grade, numStudents);
cout << "low score - " << lowest << endl;

double avg = average (scores, grade, numStudents);
cout << "mean score - " << avg << endl;

return 0;
}
