This program illustrates the use of the STL copy() algorithm to copy integers
from one vector to another.

Here are the contents of v1:
1 3 5 7 9
Press Enter to continue ...

Here are the contents of v2:
0 0 0 0 0
Press Enter to continue ...

Now we copy the values from v1 to v2 and re-display v2.
Here are the new contents of v2:
1 3 5 7 9
Press Enter to continue ...

Here are the contents of v3:
10 20 30 40 50 60 70 80 90 100
Press Enter to continue ...

Now we copy all but the end values from v2 into v3,
starting at position 5 in v3, and then re-display v3.
Press Enter to continue ...

Here are the new contents of v3:
10 20 30 40 3 5 7 80 90 100
Press Enter to continue ...

This time we also recorded the iterator returned by
the copy algorithm and now display the value it points to.
Press Enter to continue ...

The value pointed to by this iterator is 80.
