The second one is not correct. &p is the addr of p, then you use its value to point to CString.

同学，人家那个是C++。第二个是指向reference的Cstring 指针。类似第一个是CString **, 第二个是Cstring *。

引用就是静态指针，这2个函数并无本质不同，调用参数不同。CString *p;
func(&p) //func(CString** p)
func(p) // func(CString*&p)

正解,问问题的朋友可以试这样解决:化几分钟写一段测试小程序,运行比较看看.

func(CString *&);function-wise, is the same as func(CString *) that allows you to operate CString object.
For object-access, is the same as func(CString **) that allows operate both CString object and CString * object.
