Try this: using System; delegate int MyDelegate(int x int y); class Program { static void Main() { Console.WriteLine(Enter two integers
); Console.Write( First integer : ); int i1 = int.Parse(Console.ReadLine()); Console.Write( Second integer : ); int i2 = int.Parse(Console.ReadLine()); MyDelegate del = new MyDelegate(Minimum); Console.WriteLine(
The smaller of {0} and {1} is : {2} i1 i2 del(i1 i2)); del -= Minimum; // remove Mimimum from invocation list del += Maximum; // add Maximum to invocation list Console.WriteLine(The larger of {0} and {1} is : {2} i1 i2 del(i1 i2)); Console.ReadKey(); } static int Minimum(int x int y) { if (x return y; } static int Maximum(int x int y) { if (x > y) return x; return y; } }

add System.Linq in directives or Use below code if you are using the framework which doesn't support the LINQ. static void Main(string[] args) { string word =System.Console.ReadLine(); if (word == null) return; var arrWord = word.Split(' '); foreach (var wrd in arrWord) { int count = 0; for (int i = 0; i { if (wrd.Substring(i 1).ToLower() == e) count++; } if(count>=3) Console.WriteLine(wrd +  +count.ToString()); } Console.ReadKey(); }

Try this: using System; using System.Collections.Generic; using System.Text.RegularExpressions; class Program { static void Main() { List results = new List (); while(true) { Console.Write(
Enter a string or q to quit : ); string text = Console.ReadLine(); if (text == q || text == Q) return; results.Clear(); MatchCollection mc = Regex.Matches(text @\b\w+\b); foreach(Match m in mc) { int eCount = 0; foreach(char c in m.Value) { if (c == 'e' || c == 'E') eCount++; } if (eCount > 3) results.Add(m.Value); } Console.WriteLine(
Number of words which contain more than 3 'e's is {0}
 results.Count); if (results.Count > 0) { foreach(string w in results) Console.WriteLine( {0} w); } } } }

Great thank you !! Now i found another task To create delegate who will call two classes Maximum(int x int y) and Minimum (int x int y) with method that prints the value. To write code that will use delegate and first will get method Minimum and later Maximum.

it has an error: Error 1 'string' does not contain a definition for 'Where' and no extension method 'Where' accepting a first argument of type 'string' could be found (are you missing a using directive or an assembly reference?) It has to enter sentence with 5-6 words and print number of words that contain e more than 3 times. if the sentence has 2 words like that it will print > 2 Thanks for your fast reply

Are you looking for something like below code? static void Main(string[] args) { string word =System.Console.ReadLine(); if (word == null) return; var arrWord = word.Split(' '); foreach (var wrd in arrWord) { int count = wrd.Where((t i) => wrd.Substring(i 1).ToLower() == e).Count(); if(count>=3) Console.WriteLine(wrd +  +count.ToString()); } Console.ReadKey(); }
