Learn Challenge: Number Guessing Simulation | While and Do-While Loops: Control and Flexibility

In this challenge, you will apply your understanding of do-while loops by simulating a simple number guessing game. The key feature of this task is that the guessing loop must always execute at least once, regardless of whether the guess is correct on the first try. This ensures you gain practical experience using a do-while loop, which guarantees the loop body runs before any condition is checked.

            int guess = 7; // The guess is correct on the first try
            bool guessedCorrectly = false;

            do
            {
                Console.WriteLine("Guessing...");
                if (guess == secretNumber)
                {
                    guessedCorrectly = true;
                    Console.WriteLine("Correct guess!");
                }
                else
                {
                    Console.WriteLine("Wrong guess.");
                    // In a real game, the guess could be updated here
                }
            } while (!guessedCorrectly);
        }
    }
}

Task

Swipe to start coding

Simulate a number guessing game using a do-while loop. The loop should always run at least once, even if the first guess is correct.

Use the guesses array to represent a series of guesses.
Compare each guess to the secretNumber.
If a guess matches the secret number, set guessedCorrectly to true.
After each guess, increment the index variable.
Print "You guessed it!" if the guess is correct, or "Try again." if not.
