There are two string operators in C#: Equality and Inequality.ExampleLet us see an example of Equality operator − Live Demousing System; public class Demo {    public static void Main() {       string str1 = "Amit";       string str2 = " ";       Console.WriteLine("Is string1 null or empty? = "+string.IsNullOrEmpty(str1));       Console.WriteLine("Is string2 null or empty? = "+string.IsNullOrEmpty(str2));       Console.WriteLine("Is string1 equal to str2? = "+str1 == str2);    } }OutputIs string1 null or empty? = False Is string2 null or empty? = False FalseExampleLet us now see an example of C# Inequality operator − Live Demousing System; public class Demo {    public ...

The Queue.TrimExcess() method in C# is used to set the capacity to the actual number of elements in the Queue, if that number is less than 90 percent of current capacity.Syntaxpublic void TrimExcess ();Example Live Demousing System; using System.Collections.Generic; public class Demo {    public static void Main() {       Queue queue = new Queue();       queue.Enqueue(100);       queue.Enqueue(200);       queue.Enqueue(300);       queue.Enqueue(400);       queue.Enqueue(500);       queue.Enqueue(600);       queue.Enqueue(700);       queue.Enqueue(800);       queue.Enqueue(900);       queue.Enqueue(1000);       Console.WriteLine("Queue..."); ...

The Object.GetTypeCode() method in C# is used to get the Type of the current instance.SyntaxThe syntax is as follows −public Type GetType ();Example Live Demousing System; public class Demo {    public static void Main() {       Object ob = new Object();       String str = "Jim";       Type type1 = ob.GetType();       Type type2 = str.GetType();       Console.WriteLine("Type = "+type1);       Console.WriteLine("Type = "+type2);       Console.WriteLine("Hash Code = "+type1.GetHashCode());       Console.WriteLine("Hash Code = "+type2.GetHashCode());    } }OutputType = System.Object Type = System.String Hash Code = 30015890 Hash Code = 21083178Example Live Demousing System; ...

The BitConverter.ToString() method in C# is used to convert the numeric value of each element of a specified array of bytes to its equivalent hexadecimal string representation.Syntaxpublic static string ToString (byte[] val);Above, val is the byte array.Example Live Demousing System; public class Demo {    public static void Main() {       byte[] arr = {0, 10, 2, 5, 32, 45};       int count = arr.Length;       Console.Write("Byte Array... ");       for (int i = 0; i < count; i++) {          Console.Write(""+arr[i]);       }       Console.WriteLine("Byte ... Read More

The Single.Equals() method in C# is used to return a value indicating whether two instances of Single represent the same value.Syntaxpublic bool Equals (float ob); public override bool Equals (object ob);The parameter ob for the both the syntaxes is an object to compare with this instance.Example Live Demousing System; public class Demo {    public static void Main() {       float f1 = 15.9f;       float f2 = 40.2f;       Console.WriteLine("Value1 = "+f1);       Console.WriteLine("Value2 = "+f2);         Console.WriteLine("Are both the values equal? = "+f1.Equals(f2));    } }OutputValue1 = 15.9 Value2 = 40.2 Are both the values equal? = FalseExample Live ...

The BitConverter.ToChar() method in C# is used to returns a Unicode character converted from two bytes at a specified position in a byte array.Syntaxpublic static char ToChar (byte[] value, int begnIndex);Above, val is the byte array, whereas begnIndex is the beginning position within val.Example Live Demousing System; public class Demo {    public static void Main() {       byte[] arr = { 0, 20, 50, 65 };       Console.WriteLine("Array = {0} ",       BitConverter.ToString(arr));       for (int i = 1; i < arr.Length - 1; i = i + 2) {     ...

The Boolean.GetHashCode() method in C# is used to return the hash code for this instance.Syntaxpublic override int GetHashCode ();Example Live Demousing System; public class Demo {    public static void Main(String[] args){       string str = "JackSparrow!";       bool val = true;       char[] arr = { 'J', 'a'};       Console.WriteLine("String = "+str);       Console.WriteLine("String (after trim) = " + str.Trim(arr));       Console.WriteLine("String (Hashcode) = "+str.GetHashCode());       Console.WriteLine("Bool (Hashcode) = "+val.GetHashCode());    } }OutputString = JackSparrow! String (after trim) = ckSparrow! String (Hashcode) = -203134198 Bool (Hashcode) = 1Example Live Demousing System; public class Demo {    public static void ... Read More

Pod is a simple-to-use markup language used for writing documentation for Perl, Perl programs, and Perl modules. There are various translators available for converting Pod to various formats like plain text, HTML, man pages, and more. Pod markup consists of three basic kinds of paragraphs −Ordinary Paragraph − You can use formatting codes in ordinary paragraphs, for bold, italic, code-style , hyperlinks, and more.Verbatim Paragraph − Verbatim paragraphs are usually used for presenting a codeblock or other text which does not require any special parsing or formatting, and which shouldn't be wrapped.Command Paragraph − A command paragraph is used for ...

Perl kill('KILL', (Process List)) function can be used to terminate a pseudo-process by passing it the ID returned by fork().Note that using kill('KILL', (Process List)) on a pseudo-process() may typically cause memory leaks, because the thread that implements the pseudo-process does not get a chance to clean up its resources.You can use kill() function to send any other signal to target processes, for example following will send SIGINT to a process IDs 104 and 102 −#!/usr/bin/perl kill('INT', 104, 102); 1;

Perl provides a fork() function that corresponds to the Unix system call of the same name. On most Unix-like platforms where the fork() system call is available, Perl's fork() simply calls it. On some platforms such as Windows where the fork() system call is not available, Perl can be built to emulate fork() at the interpreter level.The fork() function is used to clone a current process. This call create a new process running the same program at the same point. It returns the child pid to the parent process, 0 to the child process, or under if the fork is ... Read More
