There is no such data type. However, when we use user-defined data types of our own type, then that type of data can be stored in a variable. So as a term, you may say that user-defined data type can store any data. As the data-type used in any variable will be depending upon us.
C is not an object-oriented programming language and therefore has no objects as such. However, the term is often used in a more general sense to mean any instance of an user-defined or primitive variable/constant. In C++, the term is used specifically to mean any instance of a class.

Voltage is a measure of electric 'push'. When there's nothing to push (no circuit) it has no meaning, but that isn't to say it isn't there. Just the same as if you push a car. Take the car away and your push goes away. (or does it?)
Yes a user defined exception can have any number of methods in it. A user defined exception is nothing but a Java class created for a specific purpose. Just like ordinary Java classes, you can have any number of methods in it...

Any push or pull is defined as force.This force may or may not produce motion.It might stop the moving object,change the shape,size or direction.
is force FORCE: a push or pull on an object :)
Yes.Yes.Yes.Yes.
See Wikipedia page "Pictorial Push Pull Signs for Doors".

Any object that has a mass.
No, because a wax candle does not have any magnetic pull or push.
