编写一个程序，使用while循环猜数字游戏。程序随机生成一个1到100之间的整数，然后要求用户猜这个数字是多少，直到猜对为止。

import random

answer = random.randint(1, 100)
guess = int(input("Guess the number between 1 and 100: "))

while guess != answer:
    if guess < answer:
        print("Too low, try again.")
    else:
        print("Too high, try again.")
    guess = int(input("Guess again: "))

print("Congratulations, you guessed correctly!")
