If I remove protected then it show error. Why?

Ravi said:   1 decade ago
Because on removing protected keyword int I will become public by default, and now for derived there would be two i variable.

Removing protected keyword become private. Because default scope of class member is private which is not accessible by other class or type.

Here use of protected is:

Only child class access this data.

Removing protected keyword means these variable private data type. So this variable use only base class, does not inherited child class.

Private is the default access modifier for members, if you don't specify access specifier then compiler assumes it is private, private members are not accessible in derived class hence you will get error.

If we remove protected modifier by default it become private which is not accessible in child class.

By default csharp class members are private when the access specifier is absent. So, it can't access child class features (derived class features).

Where is create object name base ?

It is directly used it.

To get output as 9 13,

First you need to get the derived class i value and then you can get the base class i value by object of base class as base.i

Where base is object of BaseClass.
