C#: Find the number and its square of an array which is more than 20

C# Sharp LINQ : Exercise-3 with Solution

Write a program in C# Sharp to find the number of an array and the square of each number which is more than 20.

Sample Solution:

C# Sharp Code:

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

class LinqExercise3
{
    static void Main(string[] args)
    {
        // Define an integer array
        var arr1 = new[] { 3, 9, 2, 8, 6, 5 };

        // Display a message indicating the purpose of the LINQ operation
        Console.Write("\nLINQ : Find the number and its square of an array which is more than 20 : "); 
        Console.Write("\n------------------------------------------------------------------------\n");	

        // Create a LINQ query to find numbers and their squares greater than 20
        var sqNo = from int Number in arr1
                    let SqrNo = Number * Number
                    where SqrNo > 20
                    select new { Number, SqrNo };

        // Iterate through the result and display numbers and their squares
        foreach (var a in sqNo)
            Console.WriteLine(a);

        Console.ReadLine(); // Wait for user input before closing the program
    }
}

Sample Output:

LINQ : Find the number and its square of an array which is more than 20 :                                     
------------------------------------------------------------------------                                      
{ Number = 9, SqrNo = 81 }                                                                                    
{ Number = 8, SqrNo = 64 }                                                                                    
{ Number = 6, SqrNo = 36 }                                                                                    
{ Number = 5, SqrNo = 25 }
