using namespace std;
int main()
{
string name="";
double testscore;
double avearge;
int sum=0;
int count=0;
char grade;

ifstream inFile;
ofstream outFile;

inFile.open("Grades.txt");
if(!inFile)
{
  cout << "Cannot open input file"<<endl;
  return 1;
}

inFile >> name;

while(inFile)
{
inFile >> testscore;
sum = sum + testscore;
count++;
    sum=sum/10;

cout<<left<<setw(12) << name
   << setprecision(2)<<setw(12) << fixed << testscore <<endl;

inFile >> name;
}

system("pause");
return 0;
