C#: Find the strings for a specific minimum length

C# Sharp LINQ : Exercise-22 with Solution

Write a program in C# Sharp to find the strings for a specific minimum length.

Sample Solution:

C# Sharp Code:

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

class LinqExercise22
{
    static void Main(string[] args)
    {
        string[] arr1; // Declare an array to store strings
        int n, i, ctr; // Declare variables to store the count, loop index, and minimum length

        // Display a message indicating the purpose of the program
        Console.Write("\nLINQ : Find the strings for a specific minimum length : ");
        Console.Write("\n------------------------------------------------------\n");

        // Ask user for the number of strings to store in the array
        Console.Write("Input number of strings to store in the array :");
        n = Convert.ToInt32(Console.ReadLine());
        arr1 = new string[n]; // Initialize the array based on user input

        // Prompt user to input strings into the array
        Console.Write("\nInput {0} strings for the array  :\n", n);
        for (i = 0; i < n; i++)
        {
            Console.Write("Element[{0}] : ", i);
            arr1[i] = Console.ReadLine(); // Store user input into the array
        }

        // Ask user for the minimum length of the item they want to find
        Console.Write("\nInput the minimum length of the item you want to find : ");
        ctr = Convert.ToInt32(Console.ReadLine());

        // Use LINQ to find strings that meet the minimum length criteria
        IEnumerable<string> objNew = from m in arr1
                                     where m.Length >= ctr
                                     orderby m
                                     select m;

        // Display the items that meet the minimum length criteria
        Console.Write("\nThe items of minimum {0} characters are : \n", ctr);
        foreach (string z in objNew)
            Console.WriteLine("Item: {0}", z);

        Console.ReadLine(); // Wait for user input before exiting
    }
}
  

Sample Output:
