Answer 3

Classes are nothing but custom datatypes. Objects are just instances of those datatypes.

Consider 'int a' and 'MyClass obj'. Both of them imply the same thing. Integer is a built in datatype whereas MyClass is a datatype that you defined. Similarly, 'a' and 'obj' are objects of their respective classes/datatypes.
