vector

I have some questions about vector in STL to clarify.....

1 Where are the objects in vector allocated? heap?

2 does vector have boundary check? If the index out of the boundary, what error will happen?

3 Why array is faster than vector?

4 Is there any case in which vector is not applicable but array is a must?
