Sample Solution:

C# Sharp Code:

using System;

// Namespace declaration
namespace exercises
{
    // Class declaration
    class Program
    {
        // Main method - entry point of the program
        static void Main(string[] args)
        {
            // Calling the 'test' method with different strings and displaying the returned values
            Console.WriteLine(test("C# Sharp")); // Output: True
            Console.WriteLine(test("C#"));       // Output: True
            Console.WriteLine(test("C++"));      // Output: False
            Console.ReadLine();                  // Keeping the console window open
        }

        // Method to test conditions based on the given string
        public static bool test(string str)
        {
            // Check if the length of the string is less than 3 and it equals "C#"
            // or if the string starts with "C#" and the third character is a space ' '
            return (str.Length < 3 && str.Equals("C#")) || (str.StartsWith("C#") && str[2] == ' ');
        }
    }
}

Sample Output:

True
True
False

Previous: Write a C# Sharp program to create a new string taking the first 3 characters of a given string and return the string with the 3 characters added at both the front and back.If the given string length is less than 3, use whatever characters are there.
Next: Write a C# Sharp program to check if one given temperatures is less than 0 and the other is greater than 100.
