Computing Grade for a course
So my program is supposed to calculate the course grade by finding the average.
ex.
Input

Lady Gaga 10 7 7 0 8 2 3 4 8 10
Mary Johnson 9 8 9 9 8 10 6 5 9 8
Robert Park 0 0 0 0 0 0 0 0 0 0
Al Robertson 10 10 10 10 10 10 10 10 10 10

Lady Gaga 10 7 7 0 8 2 3 4 8 10 (5.9)
Mary Johnson 9 8 9 9 8 10 6 5 9 8 (8.1)
Robert Park 0 0 0 0 0 0 0 0 0 0 (0)
Al Robertson 10 10 10 10 10 10 10 10 10 10 (10)

#include <iostream>
#include <fstream>

using namespace std;

{
int i, count;
string first, last;
double average, a[10], sum=0;
fin >> first;
while(fin)
{
fin >> last;
count = 0;
for(i=0; i<10; i++)
{
fin >> a[i];
sum = sum + a[i];
count++;
}
fout << first << " " << last << " ";
for(i=0; i<10; i++)
{
fout << a[i] << " ";
}
average = sum / count;
fout << average << endl;
fin >> first;
}
}
