For integer 4 similarly double, float, char. What is the value for this and all?

A size of int is 4.

How to check?


Sol- 4

But we cannot access the protected member in the object of derived class. So memory does not occupy by this.

So, 4+4() is base class and (4+4) is derived class.

By default, int is int32 in C# which takes 4 bytes.

6 fields get inherited to the class even though two can't be used.

So 6*4 =24 bytes.

Not getting this. Please explain in a correct way.

The size of a derived class object is equal to the sum of sizes of data members in base class and the derived class.

There is a private variable in the parent class.

So the child class can contain only 5 variables.
So, 5*4 = 20bytes.
