What will be the output of the C#.NET code snippet given below?

int num = 1, z = 5;

if (!(num <= 0))
    Console.WriteLine( ++num + z++ + " " + ++z ); 
else
    Console.WriteLine( --num + z-- + " " + --z ); 

1. Data
2. Class
3. Enum
4. Structure
5. Namespace

namespace CuriousTabConsoleApplication
{ 
    class SampleProgram
    { 
        static void Main(string[] args)
        { 
            int[]arr = newint[]{ 1, 2, 3, 4, 5 }; 
            fun(ref arr);
        }
        static void fun(ref int[] a)
        { 
            for (int i = 0; i < a.Length; i++)
            { 
                a[i] = a[i] * 5; 
                Console.Write(a[ i ] + " "); 
            } 
        } 
    } 
}

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;

int[ , ] intMyArr = {{7, 1, 3}, {2, 9, 6}};

1. intMyArr represents rectangular array of 2 rows and 3 columns.
2. intMyArr.GetUpperBound(1) will yield 2.
3. intMyArr.Length will yield 24.
4. intMyArr represents 1-D array of 5 integers.
5. intMyArr.GetUpperBound(0) will yield 2.
