嘿，我需要创建这个程序，要求用户输入宠物的名称，年龄，体重和类型。可用的两种类型是狗和猫。然后它将询问用户他们感兴趣的药物。有镇静剂和止痛药。无论您选择哪个选项，程序都应该应用数学公式来根据宠物的体重确切找到给您的宠物多少药物。您以磅为单位输入宠物的体重，但会将其转换为公斤。我也不完全确定petType的决策结构是否是字符串变量。我需要检查用户输入的是“狗”还是“猫”，并且我一直在使用if（petType.Contains（“ Dog”“ Cat”）== true），但这似乎正常了，但我我不确定到底每种宠物的药物使用量是否不同。我最麻烦的地方是应该为用户显示以ML为单位的金额，但是它是空白的，根本不显示任何内容。有任何想法吗？谢谢！PS：我是这个网站的新手，并认为我可以上传多少代码是有限制的。我将为您上传整个程序。抱歉！

正如评论中指出的那样，工作程序更容易进行故障排除。我已经放任自流，并稍加修改了您的代码，以消除重复的逻辑并允许更轻松的扩展（请参见SOLID）。希望这可以为您带来一些思考。
