My whole code is below. I need to print an alphabetically sorted list towards the end right now, that's where I'm at... you can see my measly attempt, but I clearly don't really know what I'm doing with this sorting algorithm... Do I need to make a new vector comprised of only the names/strings in order to do this? How is this going to work.

Thank you kindly in advance.

IIf you are going to use sort() then you need to overload the less than operator for the Records class or create some other function to compare two Record objects----say compareNames() or something.

The thing is I'm pretty sure I need to have THIS vector array sorted -- i.e., the one I already have set up with all the employees' info.

If you are going to do some othe sort routine, say a bubble sort or whatever, to sort alphabetically by name, then compare names directly, but swap the respective record objects.
