	{
		cout << "Enter name student:" << endl;
		cin >> name;
		id++;
		for (int i = 0; i < size; i++)
		{
			cin >> grade;
			if (grade > 0 && grade < 40)
			{
				arr[i] = "F";
			}
			else if (grade >= 40 && grade < 50)
			{
				arr[i] = "D";
			}
			else if (grade >= 50 && grade < 60)
			{
				arr[i] = "C";
			}
			else if (grade >= 60 && grade < 70)
			{
				arr[i] = "B";
			}
			else if (grade >= 70 && grade < 101)
			{
				arr[i] = "A";
			}
			else
			{
				cout << "Error" << endl;
				break;
