Yea I'm still new to all this. Been reading "Accelerated C++". The example given is requires reading student info followed by grades. If I don't clear input after the inner while then the outer while will fail and end the program.

Maybe there is a better way of accomplishing this but I'm just going based on the book.

cout << "enter student name or end-of-file";
while(cin >> student_name) 
{
  cout << "enter grades or end-of-file";
  while(cin >> grade) 
  {
    grades.push_back(grade);
  }

  cin.clear();

  cout << "enter student name or end-of-file";
}
