This program illustrates the use of member functions
clear(), erase(), and pop_back() for vector objects.

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

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

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

Now we remove a component from the end of v (using v.pop_back()),
and display again to confirm.
Size = 3  Capacity = 10
Contents: 1 2 9
Press Enter to continue ...

Finally, we clear v and display once again to confirm:
Size = 0  Capacity = 10
