For d we have ...
Size = 10
Contents: 1 2 3 4 5 6 7 8 9 10
Press Enter to continue ...

First, we delete the third component of d using this call to erase():
p = d.erase(d.begin()+2);
and then display the remaining values in d.
Size = 9
Contents: 1 2 4 5 6 7 8 9 10
Press Enter to continue ...

The iterator returned by the above call to erase() points to 4.

Next, we delete the 3rd through 7th components of d using this call to erase():
p = d.erase(d.begin()+2, d.begin()+7);
and then display the remaining values in d.
Size = 4
Contents: 1 2 9 10
Press Enter to continue ...

The iterator returned by the above call to erase() points to 9.

Now we remove a component from the end of d (using d.pop_back()),
and display again to confirm.
Size = 3
Contents: 1 2 9
Press Enter to continue ...

Then we remove a component from the front of d (using d.pop_front()),
and display again to confirm.
Size = 2
Contents: 2 9
Press Enter to continue ...

Finally, we clear d and display once again to confirm:
Size = 0
