Which of the following is the root of the .NET type hierarchy?

1. The program did not handle an exception called IndexOutOfRangeException.
2. The program execution continued after the exception occurred.
3. The exception occurred in line number 14.
4. In line number 14, the program attempted to access an array element which was beyond the bounds of the array.
5. The CLR could not handle the exception.

1. Freeing memory on the stack.
2. Avoiding memory leaks.
3. Freeing memory occupied by unreferenced objects.
4. Closing unclosed database collections.
5. Closing unclosed files.

   int[][][] intMyArr = new int[2][][];

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); 
        } 
    } 
}

namespace CuriousTabConsoleApplication
{ 
    class SampleProgram
    { 
        static void Main(string[ ] args)
        { 
            int a = 5;
            int s = 0, c = 0; 
            s, c = fun(a); 
            Console.WriteLine(s +" " + c) ;
        }
        static int fun(int x)
        {
            int ss, cc;
            ss = x * x; cc = x * x * x; 
            return ss, cc;
        } 
    } 
}

1. An error will be reported in the statement s, c = fun(a); since multiple values returned from a function cannot be collected in this manner.
2. It will output 25 125.
3. It will output 25 0.
4. It will output 0 125.
5. An error will be reported in the statement return ss, cc; since a function cannot return multiple values.

String s1="Kicit";
Console.Write(s1.IndexOf('c') + " "); 
Console.Write(s1.Length);

1. String s = "123"; 
   int i;
   i = (int)s;

2. String s = "123";
   int i;
   i = int.Parse(s);

3. String s = "123"; 
   int i;
   i = Int32.Parse(s);

4. String s = "123"; 
   int i;
   i = Convert.ToInt32(s);

5. String s = "123"; 
   int i;
   i = CInt(s);

    int[][]a = new int[2][];
    a[0] = new int[4]{6, 1 ,4, 3};
    a[1] = new int[3]{9, 2, 7}; 
    foreach (int[ ] i in a)
    {
        /* Add loop here */
        Console.Write(j + " ");
        Console.WriteLine(); 
    }
