嗨bado，


我可以问一个反问题：我可以猜测它会在没有运行的情况下打印出来，即使它不是程序只是一段代码 - 这会对你有所帮助吗无论如何？另一方面，这段代码没有独特的含义（我假设classA是一个引用类型，但是谁知道你可能做过类似的事情：



struct classA {}



假设你是学生/学习者我会说试着理解这个例子给你看的是什么（指针，参考，别名）。任何具体的理解问题？ - >提出具体问题....



亲切的问候

Hi bado,

May I ask a counter question: I can guess what this will print without running it, even if it's not a "Program" just a snippet of code - will this help you in any way? On the other hand this code has no unique meaning (I'd assume classA is a reference type, but who knows maybe you did something like that:

struct classA { }

Assuming you are a studend/learner I'd say try to understand what this example is showing you (pointers, references, alias). Any specific understanding problems? -> Ask a specific question....

Kind regards

Johannes
