Why can't an object of abstract class be created?

Question

Here is a scenario in my mind and I have googled, Binged it a lot but got the answer like

\"Abstract class has not implemented method so, we cant create the object\

Answer 1

every body is writing dat abstract class has some virtual function which has not defined. for dat reason we cant create object, but abstract class is a class with the key word 'abstract' which may or may not have abstract method. i think it is a concept, it does not take any memory for dat. so if we can create an object den a memory will be created which is not possible, for dat reason we can't create object of an abstract class bt we can create reference of it which does not occupy any memory location.
