Question

I posted this earlier but the answer did not provide three methods. Can you please post the answer with three methods. Also if possible can it be in C#. Java is also fine but please have three methods in the code. Also the main method.

Exercise #3 Guess the Number Write a "Guess the Number" game that randomly assigns a secret number [1,20] for the user to guess. I recommend hard coding your secret number at first to make testing your code easier You can write this a number of ways,but try to stick to the instructions outlined here. Write three methods to make your game work . The first method should generate a random number and return the value to main to store in the secret number variable. The second method should ask your user what his first guess is. Return this information to main. The third method should take in the guess and the secret number via parameters, then evaluate whether or not the guess is correct. Return a string to let the user know if their guess was too high, too low, or correct . You will need a nested loop in main. You'll want the outer loop to ask if the user wants to play again. You'll also need to think about how to include an inner loop that continues to call the third method until the user guesses correctly.
