c - 当指针出现在变量(指针*)的末尾时，这意味着什么？

Question

我已经了解了指针，但是当指针出现在像这样的变量末尾时，这意味着什么。

struct student_record_node 
{
  struct class_record* record_;
  struct class_record_node* next_;
};

Answer 1

这不是变量的结尾。 student_record_node 是用户定义的数据类型，使用结构说明符 struct 关键字指定。

引自wikipedia article对此，(强调我的)

A struct in the C programming language (and many derivatives) is a complex data type declaration that defines a physically grouped list of variables to be placed under one name in a block of memory, allowing the different variables to be accessed via a single pointer, or the struct declared name which returns the same address.

在你的情况下，

struct student_record_node 
{
  struct class_record* record_;
  struct class_record_node* next_;
};

是用户定义类型struct student_record_node 的声明，您可以通过以下语句创建该类型的变量

struct student_record_node stu_record;  //stu_record is the variable name
