        // The Main method is where the program execution begins
        static void Main(string[] args)

            // Declare variables to store the three numbers
            double a, b, c;
            double result1, result2;

            // Prompt the user to enter the first number (a)
            Console.Write("Enter the first number (a): ");
            a = Convert.ToDouble(Console.ReadLine()); // Read and convert the input to a double

            // Prompt the user to enter the second number (b)
            Console.Write("Enter the second number (b): ");
            b = Convert.ToDouble(Console.ReadLine());

            // Prompt the user to enter the third number (c)
            Console.Write("Enter the third number (c): ");
            c = Convert.ToDouble(Console.ReadLine());

            // Calculate the results of the two expressions
            result1 = (a + b) * c;
            result2 = (a * c) + (b * c);

            // Display the results
            Console.WriteLine("\nResults:");
            Console.WriteLine("({0} + {1}) * {2} = {3}", a, b, c, result1);
            Console.WriteLine("{0} * {2} + {1} * {2} = {3}", a, b, c, result2);

            // Wait for the user to press a key before closing the console window
            Console.ReadKey(); // This keeps the console window open until a key is pressed
        }
    }
}

 Output

Enter the first number (a): 2  
Enter the second number (b): 3  
Enter the third number (c): 4  

Results:  
(2 + 3) * 4 = 20  
2 * 4 + 3 * 4 = 20
