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.

Which of the following is the correct output of the C#.NET code snippet given below?

int[ , , ] a = new int[ 3, 2, 3 ];
Console.WriteLine(a.Length);

How will you complete the foreach loop in the C#.NET code snippet given below such that it correctly prints all elements of the array a?

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();
}

If a is an array of 5 integers then which of the following is the correct way to increase its size to 10 elements?

Which one of the following statements is correct?

Which of the following statements are correct about the C#.NET code snippet given below?

int[] a = {11, 3, 5, 9, 4};

1 The array elements are created on the stack.

2 Refernce a is created on the stack.

3 The array elements are created on the heap.

4 On declaring the array a new array class is created which is derived from System.Array Class.

5 Whether the array elements are stored in the stack or heap depends upon the size of the array.

Which of the following statements are correct about the C#.NET code snippet given below?

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

2 intMyArr represents rectangular array of 2 rows and 3 columns.

3 intMyArr.GetUpperBound(1) will yield 2.

4 intMyArr.Length will yield 24.

5 intMyArr.GetUpperBound(0) will yield 2.
