To display a line, Console.Write() is used in C#.Console displays the result on the console. I have first set a string.string str = "Tom Hanks is an actor";Now displaying the above line.Console.WriteLine(str);The following is the complete code −Example Live Demousing System; namespace Program {    public class Demo {       public static void Main(String[] args) {          string str = "Tom Hanks is an actor";          Console.WriteLine("Displaying a line below");          Console.WriteLine(str);          Console.ReadLine();       }    } }OutputDisplaying a line below Tom Hanks is an actor

With C#, you can easily display the following diamond shape.$ $$$ $$$$$ $$$$$$$ $$$$$$$$$ $$$$$$$ $$$$$ $$$ $To display a diamond shape, you need to focus on the following points −Number of rows Dollar sign to be displayed Empty spacesConsidering the above you can easily create the diamond shape as shown in the below code −Example Live Demousing System; namespace Program {    public class Demo {       public static void Main(String[] args) {          int i, j, r, d, e;          // rows = 5          r = 5;          // display dollar sign          d = 1;          // empty space          e = r - 1;          for (i = 1; i < r * 2; i++) {             // display empty space             for (j = 1; j

Binary triangle is formed with 0s and 1s. To create one, you need to work around a nestes for loop and display 0s and 1s till the row entered.for (int i = 1; i

To display a line in C#, use the Console.WriteLine().Under that set a blank line −Console.WriteLine(" ");The following is the code that displays a blank line −Example Live Demousing System; namespace Program {    public class Demo {       public static void Main(String[] args) {          Console.WriteLine(" ");          Console.WriteLine("Displayed a blank line above!");          Console.ReadLine();       }    } }OutputDisplayed a blank line above!

To find the difference between two dates in C#, you need to first set two dates to be compared using the DateTime object. We will use the DateTime class in C#.Date 1DateTime date1 = new DateTime(2018, 09, 15); Console.WriteLine("Date 1 : {0}", date1);Date 2DateTime date2 = new DateTime(2018, 09, 28); Console.WriteLine("Date 2 : {0}", date2);Now let us compare both the dates in C#. The following is an example to compare dates in C#.Example Live Demousing System; namespace Program {    class Demo {       static int Main() {          DateTime date1 = new DateTime(2018, 09, 15); ...

To display multiplication table, you need to set the numbers and format the output property. Let’s say you want to find the table of 4 from 1 to 10. For that, set a while loop first till 10.while (a

Set the stringstring s = "Tom Cruise";Now let’s say you need to find the substring “Tom”, then use the Contains() method.if (s.Contains("Tom") == true) {    Console.WriteLine("Substring found!"); }The following is the code to learn how to find a substring from a string −Example Live Demousing System; public class Demo {    public static void Main() {       string s = "Tom Cruise";       if (s.Contains("Tom") == true) {          Console.WriteLine("Substring found!");       } else {          Console.WriteLine("Substring not found!");       }    } }OutputSubstring found!

Firstly, set the string to be replaced.string str = "Demo text!";Now use the replace() method to replace the above string.string res = str.Replace("Demo ", "New ");The following is the complete code to replace a word in a string.Example Live Demousing System; public class Demo {    public static void Main() {       string str = "Demo text!";       Console.WriteLine(str);       string res = str.Replace("Demo ", "New ");       Console.WriteLine("After replacing...");       Console.WriteLine(res);    } }OutputDemo text! After replacing... New text!

To find a number in a string, use Regular Expressions.We have set the Regex pattern to get number from a string.Regex r = new Regex(@"\d+");Now, use Match class in C# to set the string.Match m = r.Match("Welcome! We are open 365 days in a year!");Use the Success property now to display the result if number is found in the string as shown in the following complete code −Example Live Demousing System; using System.Text.RegularExpressions; class Demo {    static void Main() {       Regex r = new Regex(@"\d+");       Match m = r.Match("Welcome! We are open ... Read More

Firstly, set the first two numbers −double val1, val2; val1 = 10; val2 = 5;Now use the Math.Sqrt function to use Pythagoras Theorem.res = Math.Sqrt(val1 * val1 + val2 * val2);Example Live Demousing System; public class Program {    public static void Main(string[] args) {       double val1, val2, res;       val1 = 10;       val2 = 5;       res = Math.Sqrt(val1 * val1 + val2 * val2);       Console.WriteLine("Result = {0}", res);       Console.ReadLine();    } }OutputResult = 11.1803398874989
