double average=0.0;
ifstream randomFile;
randomFile.open("Random.txt");
if (randomFile.fail())
cout << "failed to read file.";
else
{
while (randomFile >> aNumber)
{
numbers++;
sum+=aNumber;
}
if (numbers>0)
average = sum/numbers;
else
average=0.0;
cout << "Number of numbers: " << numbers << "\n";
cout << "Sum of the numbers: " << sum << "\n";
cout << "Average of the numbers: " << average;
}
randomFile.close();
return 0;
}
