How many bytes will the structure variable samp occupy in memory if it is defined as shown below?

class Trial
{ 
    int i; 
    Decimal d;
}
struct Sample
{
    private int x; 
    private Single y; 
    private Trial z;
}
Sample samp = new Sample();

struct Book
{
    private String name; 
    protected int totalpages; 
    public Single price; 
    public void Showdata()
    {
        Console.WriteLine(name + " " + totalpages + " " + price);
    } 
    Book()
    {
        name = " "; 
        totalpages = 0;
        price = 0.0f; 
    } 
} 
Book b = new Book();

1. We cannot declare the access modifier of totalpages as protected.
2. We cannot declare the access modifier of name as private.
3. We cannot define a zero-argument constructor inside a structure.
4. We cannot declare the access modifier of price as public.
5. We can define a Showdata() method inside a structure.

struct Emp
{
    public String name;
    public int age;
    public Single sal; 
}
Emp e = new Emp();

e.name = "Amol"; 
e.age = 25; 
e.sal = 5500;

With e
{
    .name = "Amol";
    .age = 25;
    .sal = 5500; 
}

With emp e
{
    .name = "Amol";
    .age = 25;
    .sal = 5500; 
}

e -> name = "Amol"; 
e -> age = 25;
e -> sal = 5500;

name = "Amol"; 
age = 25;
sal = 5500;

1. A class is a reference type, whereas a struct is a value type.
2. Objects are created using new, whereas structure variables can be created either using new or without using new.
3. A structure variable will always be created slower than an object.
4. A structure variable will die when it goes out of scope.
5. An object will die when it goes out of scope.

1. A struct can contain properties.
2. A struct can contain constructors.
3. A struct can contain protected data members.
4. A struct cannot contain methods.
5. A struct cannot contain constants.
