Answer / govind verma
there are mainly two types of inheritance--
1) Implementation inheritance--when a class is derived from
another class such that it inherits all the members of base
type.
2) Interface Inheritance--when a type inherits only
signature of functions of another type . it does not uses
constructor.

An interface has all public members and no implementation. An abstract class is a class which may have the usual flavors of class members (private, protected, etc.), but has some abstract methods.

i have a question which is quite simple but yet complicated for me my question is why do we use void, if it does not return anything to the compiler? if it is used for normal display it can also be done by what is called Console.Write() or Consol.WriteLine() and if i do not use void with my method then my compiler throws me an error. if i return a value say integer then i write public int fun() display of the result can also be done here then why is it so necessary to use void with a function and why so compiler throw us an error if v don't use void return type?
