All arrays consist of contiguous memory locations. The lowest address corresponds to the first element and the highest address to the last element.Firstly, declare an array −int[] rank;But declaring an array does not initialize the array in the memory. When the array variable is initialized, you can assign values to the array.Array is a reference type, so you need to use the new keyword to create an instance of the array. For example, int[] rank = new int[5]; You can assign values to an array at the time of declaration −int[] rank = { 1, 2, 3, 4, 5};With that, ... Read More

Bitwise Left shift operatorThe left operands value is moved left by the number of bits specified by the right operand.Bitwise Right shift operatorThe left operands value is moved right by the number of bits specified by the right operand.The following is an example showing how to work with Bitwise left and right shift operators −Example Live Demousing System; namespace Demo {    class Program {       static void Main(string[] args) {          int a = 60; /* 60 = 0011 1100 */          int b = 13; /* 13 = 0000 1101 */          int c = 0;          c = a > 2; /* 15 = 0000 1111 */          Console.WriteLine("Value of c is {0}", c);          Console.ReadLine();       }    } }OutputValue of c is 240 Value of c is 15

Like any other object-oriented language, C# also has object and classes. Objects are real-world entities and instance of a class. Access the members of the class using an object.To access the class members, you need to use the dot (.) operator after the object name. The dot operator links the name of an object with the name of a member, for example, Box Box1 = new Box();Above you can see Box1 is our object. We will use it to access the members −Box1.height = 7.0;You can also use it to call member functions −Box1.getVolume();The following is an example showing how ... Read More

Example Live Demousing System; using System.Collections; namespace Demo {    class Program {       static void Main(string[] args) {          SortedList s = new SortedList();          s.Add("S1", "Electronics");          s.Add("S2", "Clothing");          s.Add("S3", "Applicances");          s.Add("S4", "Books");          s.Add("S5", "Accessories");          s.Add("S6", "Musical Instruments");          Console.WriteLine("Count = " + s.Count);       }    } }OutputCount = 6

To find how many elements are added in the Stack class, you need to use the Count property.Let us first add elements in the Stack −Stack st = new Stack(); st.Push('H'); st.Push('I'); st.Push('J'); st.Push('K'); st.Push('L'); st.Push('M'); st.Push('N'); st.Push('O');Now count the number of elements in the Stack −Console.WriteLine("Count: "+st.Count);Let us see the complete code −Example Live Demousing System; using System.Collections; namespace Demo {    class Program {       static void Main(string[] args) {          Stack st = new Stack();          st.Push('H');          st.Push('I');          st.Push('J'); ...

Use the Count property to find the count of elements of the Queue class. Set elements like the following declaration −Queue q = new Queue(); q.Enqueue(1); q.Enqueue(2); q.Enqueue(3); q.Enqueue(4);Then use the Count property to count the elements −q.CountThe following is an example showing how to work with Count property in Queue Class −Example Live Demousing System; using System.Collections; namespace Demo {    class Program {       static void Main(string[] args) {          Queue q = new Queue();          q.Enqueue(1);          q.Enqueue(2);          q.Enqueue(3);          q.Enqueue(4);          Console.WriteLine("Total elements: {0} ", q.Count);              Console.ReadKey();       }    } }OutputTotal elements: 4

To find the count of elements of Hashtable class, use the Count property. Firstly, set the Hashtable class with elements −Hashtable ht = new Hashtable(); ht.Add("One", "Tom"); ht.Add("Two", "Jack"); ht.Add("Three", "Peter"); ht.Add("Four", "Russel"); ht.Add("Five", "Brad"); ht.Add("Six", "Bradley"); ht.Add("Seven", "Steve"); ht.Add("Eight", "David");Now, count the number of elements using the Count property −ht.CountThe following is the complete example to learn about the usage of Hashtable Count property in C#.Example Live Demousing System; using System.Collections; namespace Demo {    class Program {       static void Main(string[] args) {          Hashtable ht = new Hashtable();     ...

Count the number of elements in the BitArray class using the Count property.Let us first set our BitArray class −BitArray arr = new BitArray(10);Now use the Count property as shown below −Example Live Demousing System; using System.Collections; public class Demo {    public static void Main() {       BitArray arr = new BitArray(10);       Console.WriteLine( "Count: {0}", arr.Count );    } }OutputCount: 10

The capacity property in SortedList class has the maximum size of the SortedList.The default capacity of a SortedList is 16.You can try to run the following the code to implement Capacity property of SortedList class in C# −Example Live Demousing System; using System.Collections; namespace Demo {    class Program {       static void Main(string[] args) {          SortedList s = new SortedList();          s.Add("S1", "Maths");          s.Add("S2", "Science");          s.Add("S3", "English");          s.Add("S4", "Economics");          Console.WriteLine("Capacity = " ...

The Count property in the ArrayList class counts the number of elements in the ArrayList.Firstly, add elements to the ArrayList −ArrayList arrList = new ArrayList(); arrList.Add(98); arrList.Add(55); arrList.Add(65); arrList.Add(34);Then get the count of the array list −arrList.CountThe following is the code to implement Count property in C# −Example Live Demousing System; using System.Collections; class Demo {    public static void Main() {       ArrayList arrList = new ArrayList();       arrList.Add(98);       arrList.Add(55);       arrList.Add(65);       arrList.Add(34);       Console.WriteLine("Count = " + arrList.Count);    } }OutputCount = 4
