一是,假设第一个链表结点是头结点(不包含实际数据,方便后续操作),那么这个结点的一个成员变量prev就不好赋空,因为NULL是赋给指针的,int a=NULL编译器会警告. 二是根本原因,The error means that you try and add a member to thestructof a type that isn't fully defined yet, so the compiler cannot k...
cpp报错:C-struct error-Field has incomplete type 程序定义如下代码: structNode { Nodeson; }; 1. 2. 3. 4. The error means that you try and add a member to the struct of a type that isn’t fully defined yet, so the compiler cannot know its size in order to determine...
variable has incomplete type 'struct stat' 文心快码 1. 解释“incomplete type 'struct stat'”错误信息的含义 “incomplete type 'struct stat'”错误信息意味着编译器在编译时遇到了对struct stat的引用,但尚未看到该结构体的完整定义。在C或C++中,结构体必须在使用前被完整定义,否则编译器无法确定其大小和布局...

hides any previously declared meaning for the name name in the tag name space and declares name as a new struct name in current scope, which will be defined later. Until the definition appears, this struct name has incomplete type.
