Last update on December 20 2024 12:42:33 (UTC/GMT +8 hours)

Write a program in C# Sharp to display the characters and frequency of each character in a given string.

Sample Solution:

C# Sharp Code:

using System;
using System.Linq;
using System.Collections.Generic;

class LinqExercise5
{
    static void Main(string[] args)
    {
        string str; // Declare a string variable to store user input

        // Display a message prompting the user to input a string
        Console.Write("\nLINQ : Display the characters and frequency of character from giving string : "); 
        Console.Write("\n----------------------------------------------------------------------------\n");	
        Console.Write("Input the string : ");

        // Read the string input from the user
        str = Console.ReadLine();
        Console.Write("\n");

        // Group the characters in the string by their values and count occurrences
        var FreQ = from x in str  
                    group x by x into y  
                    select y;  

        // Display the frequency of characters
        Console.Write("The frequency of the characters are :\n");
        foreach(var ArrEle in FreQ)  
        {  
            Console.WriteLine("Character " + ArrEle.Key + ": " + ArrEle.Count() + " times");  
        }  
    }
}
 

Sample Output:

LINQ : Display the characters and frequency of character from giving string :                                                                 
----------------------------------------------------------------------------                                                                  
Input the string : w3resource                                          
                                                                       
The frequency of the characters are :                                  
Character w: 1 times                                                   
Character 3: 1 times                                                   
Character r: 2 times                                                   
Character e: 2 times                                                   
Character s: 1 times                                                   
Character o: 1 times                                                   
Character u: 1 times                                                   
Character c: 1 times
