namespace IndiabixConsoleApplication
{ 
    struct Sample
    {
        public int i;
    }
    class MyProgram
    { 
        static void Main(string[] args)
        {
            Sample x = new Sample();
            Sample y;
            x.i =            y = x;
            y.i =            Console.WriteLine(x.i + " " + y.i); 
        } 
    } 
}

The space required for structure variables is allocated on stack.

Which of the following will be the correct output for the C#.NET program given below?

namespace IndiabixConsoleApplication
{ 
    struct Sample
    { 
        public int i;
    }
    class MyProgram
    { 
        static void Main(string[] args)
        {

        }
        public static void fun(ref Sample y)
        {

Which of the following statements is correct?

Which of the following statements are correct about Structures used in C#.NET?

1. A Structure can be declared within a procedure.
2. Structs can implement an interface but they cannot inherit from another struct.
3. struct members cannot be declared as protected.
4. A Structure can be empty.
5. It is an error to initialize an instance field in a struct.

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();

Creating empty structures is allowed in C#.NET.

Which of the following statements are correct about the structure declaration given below?

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

Which of the following will be the correct result of the statement b = a in the C#.NET code snippet given below?

    private String city; 
}
Address a = new Address(); 
Address b; 
b = a;

Which of the following will be the correct output for the C#.NET program given below?

    }
    class MyProgram
    { 
        static void Main()
        {
            Sample x = new Sample(); 
            x.i =
            fun(x); 
            Console.Write(x.i + " ");
        }
        static void fun(Sample y)
        {
            y.i =
            Console.Write(y.i + " ");
        } 
    } 
}

Which of the following statements are correct?

2. A struct can contain constructors.
3. A struct can contain protected data members.
4. A struct cannot contain methods.

Which of the following is the correct way to define a variable of the type struct Emp declared below?

struct Emp
{
    private String name; 
    private int age; 
    private Single sal;
}

1. Emp e(); e = new Emp();
2. Emp e = new Emp;
3. Emp e; e = new Emp;
4. Emp e = new Emp();
5. Emp e;
