Question : Whether b.x =1 statement in class A and class B is okay or not ?

public class A

{

int x;

static void SetX(B b)

{

b.x = 1; }

}

public class B : A

{

static void SetX(B b)

{

b.x = 1;

}

}

Answer :

b.x = 1 in Class A is fine.

b.x = 1 in Class B gives compilation error

Help :

As x is private field in Class A hence accessible within Class A
As x is private field in Class A and hence not accessible in Class B
