我应该创建一个程序，提示用户输入一个整数作为机密的最高值，并对其进行一些猜测。该程序生成一个秘密号码。在他们用尽所有猜测或猜测正确后，我的程序应该询问用户是否想再次播放。目前，我对if语句有问题，该语句用于确定某人是否回答正确，然后询问他们是否愿意查看秘密号码。目前，当我这样做时，无论我猜测是否正确，它仍然会导致密码询问用户是否希望显示它。我不知道该怎么办。同样在while循环结束时，在程序接近结束时，我想在第二轮比赛后询问用户是否愿意再次比赛。但由于某些原因，它被忽略了，同时将下一个布尔值输入设置为false为下面的TrueOrFalse布尔值。如果有人能就如何缩短代码提出建议，那就太好了！抱歉问了这么多问题，我真的被卡住了。如果你能帮忙的话，谢谢你。

首先，if(loop = false)应该是if(loop == false)，您还忘记在if语句后面添加括号{}。此外，您的播放语句位于seeSecretNumber if语句中。我也没有看到if(playAgain)的声明。我建议重新看一下节目的结尾。
