• Which of the following are the correct ways to define an array of 2 rows and 3 columns? int[ , ] a; a = new int[2, 3]{{7, 1, 3},{2, 9, 6}}; int[ , ] a; a = new int[2, 3]{}; int[ , ] a = {{7, 1, 3}, {2, 9,6 }}; int[ , ] a; a = new int[1, 2]; int[ , ] a; a = new int[1, 2]{{7, 1, 3}, {2, 9, 6}};
• Which of the following is the correct way to define and initialise an array of 4 integers? int[] a = {25, 30, 40, 5}; int[] a; a = new int[3]; a[0] = 25; a[1] = 30; a[2] = 40; a[3] = 5; int[] a; a = new int{25, 30, 40, 5}; int[] a; a = new int[4]{25, 30, 40, 5}; int[] a; a = new int[4]; a[0] = 25; a[1] = 30; a[2] = 40; a[3] = 5;
• 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);
• Which of the following statements are correct about the C#.NET code snippet given below? int[][]intMyArr = new int[2][]; intMyArr[0] = new int[4]{6, 1, 4, 3}; intMyArr[1] = new int[3]{9, 2, 7};
• Which of the following statements is correct about the C#.NET code snippet given below? int[] intMyArr = {11, 3, 5, 9, 4};
• 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}; The array elements are created on the stack. Refernce a is created on the stack. The array elements are created on the heap. On declaring the array a new array class is created which is derived from System.Array Class. Whether the array elements are stored in the stack or heap depends upon the size of the array.
• Which of the following is the correct output of the C#.NET code snippet given below? int[][] a = new int[2][]; a[0] = new int[4]{6, 1, 4, 3}; a[1] = new int[3]{9, 2, 7}; Console.WriteLine(a[1].GetUpperBound(0));
• What will be the output of the C#.NET code snippet given below? namespace CuriousTabConsoleApplication { class SampleProgram { static void Main(string[ ] args) { int i, j; int[ , ] arr = new int[ 2, 2 ]; for(i = 0; i < 2; ++i) { for(j = 0; j < 2; ++j) { arr[i, j] = i * 17 + i * 17; Console.Write(arr[ i, j ] + " "); } } } } }
• Which of the following statements are correct about arrays used in C#.NET? Arrays can be rectangular or jagged. Rectangular arrays have similar rows stored in adjacent memory locations. Jagged arrays do not have an access to the methods of System.Array Class. Rectangular arrays do not have an access to the methods of System.Array Class. Jagged arrays have dissimilar rows stored in non-adjacent memory locations.
• Which of the following is the correct way to obtain the number of elements present in the array given below? int[] intMyArr = {25, 30, 45, 15, 60}; intMyArr.GetMax; intMyArr.Highest(0); intMyArr.GetUpperBound(0); intMyArr.Length; intMyArr.GetMaxElements(0);
