推荐答案

我们做的不做你的功课：这是有原因的。它就是为了让你思考你被告知的事情，并试着理解它。它也在那里，以便您的导师可以识别您身体虚弱的区域，并将更多的注意力集中在补救措施上。



亲自尝试，你可能会发现它不是像你想的那么难！但要记住：用户输入的所有内容都是一系列字符：'A'是字符，'9'是字符。 ENTER是一个角色：'\ n'

所以我强烈建议你再次阅读你的作业问题 - 从你的描述中可以清楚地看出你老师希望你做的事情。 />


如果您遇到特定问题，请询问相关问题，我们会尽力提供帮助。但我们不打算为你做这一切！

We do not do your homework: it is set for a reason. It is there so that you think about what you have been told, and try to understand it. It is also there so that your tutor can identify areas where you are weak, and focus more attention on remedial action.

Try it yourself, you may find it is not as difficult as you think! But bear in mind: everything the user enters is a sequence of characters: 'A' is a character, '9' is a character. ENTER is a character: '\n'
So I'd strongly suggest you read your homework question again - it's not at all clear from your description exactly what your teacher expects you to do.

If you meet a specific problem, then please ask about that and we will do our best to help. But we aren't going to do it all for you!
