Consider the following fragment ---

int value;
cout << "enter an integer: ";
cin >> value;
  
switch(value):
{
    case 1:
        cout << "one";
        break;
    case 2:
        cout << "two";
    case 3:
        cout << "three";
        break;
    default:
        cout << "four";
}
cout << "done" << endl;

a)   If, when this fragment is run, the 
     user types 3, what will be printed to
     the screen after this?

b)  The user runs this fragment a 
    second time. This time, the user types
    2. What will be printed to the screen 
    after this?

c)  The user runs this fragment a third 
    time. This time, the user types
    56. What will be printed to the screen
    after this?
