Find out the index of a vector which has the min element

[Plissken.s]

Hi,
How can I find out the index of a vector which has the min element?
I know how to find out the * value * of a vector which has the min
element.
But how can I find out its index?

for example, [100, 98, 1, 98, 28], I would like the function to return
2.

Thank you.

return min_element( vec.begin(), vec.end() ) - vec.begin();

If you can find the value, couldn't you _remember_ the index where you
found it? How _do_ you find the "value"?

Look in the header <algorithm> for something akin to "min element".

Hm, are you sure this isn't HOMEWORK?

I'm pretty sure it is, because of the suggestive wording. I just hope
nobody writes your code for you.

I don't, so you're way ahead of me there. How do you define the value
of a vector, as something other than the vector, that is?

Of course somebody did...

This fact, that people do post homework here, and the fact that other
people actually do their homework, here, must be saying something.

I'm just not sure what.

I'm in a bad mood, what can I say. I've done three homework problems
already today. :-/

I can't always tell though.

I enjoy writing solutions to homework assignments and I post them
if I think that the solution is kind "creative". For most of these
"solutions" it should be pretty clear that they weren't written by
the student...

Well, yes, that's something else entirely. The last one I saw from you
could absolutely never be mistaken for something a student produced...
;-) I enjoy them immensely (and perhaps some homework poster will
actually hand in such a solution!), keep 'em coming!
