Question

What kind of loop should be used in a game where the user is guessing a secret code and the message"guess again" appears until the user guesses correctly?

Answer 1

While loop

Step-by-step explanation:

It should be noted that the number of times which the computer will ask the user to take a guess is not known.

When we have a condition like this, the while loop (or in some programs; the do-while loop) is to be used.

To further back my point, see the following program in python.

secret_code = 1234

user_guess = int(input("Take a guess: "))

while user_guess != secret_code:

user_guess = int(input("guess again: "))

print("You guessed right")

The above program will keep asking the user to take a guess until the user enters 1234.

This may or may not be possible with a for loop.
