Which of the following is the correct way of setting values into the structure variable e defined below?

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

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.

    int[] intMyArr = {25, 30, 45, 15, 60};

1. intMyArr.GetMax;
2. intMyArr.Highest(0);
3. intMyArr.GetUpperBound(0);
4. intMyArr.Length;
5. intMyArr.GetMaxElements(0);

1. Arrays can be rectangular or jagged.
2. Rectangular arrays have similar rows stored in adjacent memory locations.
3. Jagged arrays do not have an access to the methods of System.Array Class.
4. Rectangular arrays do not have an access to the methods of System.Array Class.
5. Jagged arrays have dissimilar rows stored in non-adjacent memory locations.

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.

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

namespace CuriousTabConsoleApplication
{ 
    struct Sample
    {
        public int i;
    }
    class MyProgram
    { 
        static void Main()
        {
            Sample x = new Sample(); 
            x.i = 10; 
            fun(x); 
            Console.Write(x.i + " ");
        }
        static void fun(Sample y)
        {
            y.i = 20; 
            Console.Write(y.i + " ");
        } 
    } 
}

namespace CuriousTabConsoleApplication
{ 
    struct Sample
    {
        public int i;
    }
    class MyProgram
    { 
        static void Main(string[] args)
        {
            Sample x = new Sample();
            Sample y;
            x.i = 9;
            y = x;
            y.i = 5;
            Console.WriteLine(x.i + " " + y.i); 
        } 
    } 
}
