Which of the following loop correctly prints the elements of the array?

char[ ] arr = new char[ ] {'k', 'i','C', 'i','t'} ;

namespace CuriousTabConsoleApplication
{ 
    class SampleProgram
    {
        static void Main(string[] args)
        { 
            int num = 1;
            funcv(num); 
            Console.Write(num + ", "); 
            funcr(ref num); 
            Console.Write(num + ", ");
        }
        static void funcv(int num)
        { 
            num = num + 10; Console.Write(num + ", ");
        }
        static void funcr (ref int num)
        { 
            num = num + 10; Console.Write(num + ", ");
        } 
    } 
}

1. true
2. false
3. new
4. ~
5. sizeof

int i = 20 ;
for( ; ; )
{
    Console.Write(i + " "); 
    if (i >= -10)
        i -= 4; 
    else 
        break;
}

1. static
2. protected
3. private
4. shared
5. public

1. Integer
2. Array
3. Single
4. String
5. Long

byte a = 11, b = 22, c;
