c# - Understanding default access modifiers -

i confused access modifiers, thought ask couple of quick questions clarification:

is case in absence of access modifiers data members of class, default private, though class internal?

class {     int x; }

so, int x private int x , class a internal class a?

=========================================

also, why following code not compile?

class {     protected int x; }  public class b : {}

as documentation states, classes , structs default internal , members private.

the code won't compile because, error message state, cannot inherit less accessible class. in case child class public , parent internal.
