What will be the size of the object created by the following C#.NET code snippet?
namespace IndiabixConsoleApplication
{
class Baseclass
{
private int i;
protected int j;
public int k;
}
class Derived: Baseclass
{
private int x;
protected int y;
public int z;
}
class MyProgram
{
static void Main (string[ ] args)
{
Derived d = new Derived();
}
}
}

There is a private variable in the parent class.
So the child class can contain only 5 variables.
So, 5*4 = 20bytes.

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

Not getting this. Please explain in a correct way.

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.

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

A size of int is 4.
How to check?
Console.WriteLine(sizeof(int));
Sol- 4

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

Each integer (int) type data requires 4 bytes since in this program total 6 int data type variables are given.
Hence we can calculate the required memory for object by multiplying number of int variable and the 4 bytes memory required by each variable that is 6*4=24. :).
