The Program in C# Program to Check Whether Given word is Plural or not is given below:

using System;

namespace PluralChecker
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Hello Codeauri Family ,enter a word here to check whether the word is plural or not!: ");
            string inputWord = Console.ReadLine();

            if (inputWord.EndsWith("s"))
            {
                Console.WriteLine("Okay, the word is plural.");
            }
            else
            {
                Console.WriteLine("Okay,the word is not plural.");
            }
        }
    }
}

Output:

Hello Codeauri Family ,enter a word here to check whether the word is plural or not!: codes
Okay, the word is plural.

Pro-Tips💡

Here are the step by step execution of above program:

1. We start by including the System namespace, which provides access to various types and methods used in the program, including the Console class for reading input from the user and writing output to the console.
2. We define a Program class, which contains the Main method that is the entry point of the program.
3. In the Main method, we write a prompt to the console asking the user to enter a word using Console.WriteLine("Hello Codeauri Family ,enter a word here to check whether the word is plural or not!: ").
4. We then read the user’s input using string inputWord = Console.ReadLine();. The ReadLine method is used to read a line of text from the console, which in this case will be the word entered by the user.
5. Next, we use an if statement to check if the word ends with the letter ‘s’ using inputWord.EndsWith("s"). If it does, the word is considered plural, and we write “Okay, the word is plural.” to the console using Console.WriteLine("Okay, the word is plural."). If it doesn’t, we write “Okay, the word is not plural.” to the console using `Console.WriteLine(“Okay, the word is not plural.”)
