Doubt regarding size

#1

as it has been said that class does not take any space.
but this code is showing size of class as 28.
why

#2

data members that you used i.e price , model_no they use space when u declare object of class Car.

#3

Yes , Class is just a way to (Programming paradigm -OOPS) wrap up data together and use as a single entity. And that can be done using objects/instance of the class.

#4

but here I have not created any object still it is giving size.
if memory gets allocated only when object is created and here I have not created any object…so why is output

#5

Hi Gaurav, the size that is being shown on output screen is the number of bytes Car class will take when an object of it is instantiated.
