C#: Create a new string from a given string with the first character added at the front and back

C# Sharp Basic: Exercise-17 with Solution

Write a C# program to create a string from a given string (length 1 or more) with the first character added at the front and back.

Sample Solution:-

C# Sharp Code:

using System;
using System.Text;

// This is the beginning of the Exercise17 class
public class Exercise17 {
    // This is the main method where the program execution starts
    static void Main(string[] args)
    {
        string str; // Declaring a variable to store the input string

        // Prompting the user to input a string
        Console.Write("Input a string : ");
        str = Console.ReadLine(); // Reading the input string from the user

        // Checking if the input string has a length of at least 1 character
        if (str.Length >= 1)
        {
            var s = str.Substring(0, 1); // Extracting the first character of the string

            // Printing the string with the first character added at the beginning and end
            Console.WriteLine(s + str + s);
        }
    }
}

Sample Output:

Input a string : The quick brown fox jumps over the lazy dog.          
TThe quick brown fox jumps over the lazy dog.T
