After i updated my iPhone i realized i do not have my camera anymore how to get it back? I also using a new notebook so I do not have a back up to transfer it from. Please help

I'm assuming you mean you don't have your camera application (which is not saved on any backup anyway).

One way to find it is to get to your home screen, swipe the screen from right to left, and type "Camera" in the search field. Camera is a core Apple app and cannot be deleted, so it must be there somewhere.

An alternate approach is to do Settings > General > Reset > Reset Home Screen Layout
