        if the value entered is higher  than the number
        let the user know so that the user can reduce its value
        for the next attempt.
        if the value entered is lower than the number
        let the user know so that the user can increase its
        value.

        If the user fails to find the number,
        ask the user if he wants to stop.
        If the user enter yes, stop program.
