C# number guessing game.

Let's create a number guessing game.

class NumberGuessingGame
{
    static void Main()
    {
        Random random = new Random();
        int targetNumber = random.Next(1, 101); // Generates a random number between 1 and 100
        int guess = 0;
        int attempts = 0;

        Console.WriteLine("Welcome to the 'Guess the Number' game!");
        Console.WriteLine("I have chosen a number between 1 and 100. Try to guess it!");

        while (guess != targetNumber)
        {
            Console.Write("Enter your guess: ");
            string input = Console.ReadLine();

            if (int.TryParse(input, out guess))
            {
                attempts++;
                if (guess < targetNumber)
                {
                    Console.WriteLine("The number is higher.");
                }
                else if (guess > targetNumber)
                {
                    Console.WriteLine("The number is lower.");
                }
                else
                {
                    Console.WriteLine($"Congratulations! You guessed the number {targetNumber} in {attempts} attempts.");
                }
            }
            else
            {
                Console.WriteLine("Please enter a valid number.");
            }
        }
    }
}

That's the code for this game.
Now let me explain the whole code.

• Generates a random number between 1 and 100.

• Prompts the user to guess the number.

• Provides hints if the guessed number is higher or lower than the target number.

• Notifies the user of the number of attempts when the correct number is guessed.

1. Random Number Generation:

• Random random = new Random(); creates a new instance of the Random class.

• int targetNumber = random.Next(1, 101); generates a random integer between 1 and 100.

1. Initial Setup:

   • int guess = 0; initializes the guess variable.
   • int attempts = 0; initializes the attempts counter.

2. Welcome Messages:

   • Console.WriteLine("Welcome to the 'Guess the Number' game!"); prints a welcome message.
   • Console.WriteLine("I have chosen a number between 1 and 100. Try to guess it!"); prints instructions for the game.

3. Guessing Loop:

   • The while loop continues until the user guesses the correct number (guess != targetNumber).
   • Inside the loop, the user is prompted to enter a guess with Console.Write("Enter your guess: ");.
   • The input is read using string input = Console.ReadLine();.

4. Input Validation and Feedback:

   • if (int.TryParse(input, out guess)) checks if the input is a valid integer.
   • If the input is valid, the number of attempts is incremented (attempts++;).
   • The program then checks if the guess is less than, greater than, or equal to the target number and provides feedback accordingly:
     • Console.WriteLine("The number is higher."); if the guess is less than the target number.
     • Console.WriteLine("The number is lower."); if the guess is greater than the target number.
     • Console.WriteLine($"Congratulations! You guessed the number {targetNumber} in {attempts} attempts."); if the guess is correct.
   • If the input is not valid, the user is prompted to enter a valid number with Console.WriteLine("Please enter a valid number.");.
