Accessing std::vector data through pointer to first element.

[Pete Becker]

That's not from experience. It was a little before my time. It's from

(The first
program I ever wrote was for an IBM 1401.)

Mine was a GE 635. We didn't get to run anything, but we did get to go
into the room where the machine was located.
