解决办法:包含对应头文件。 第二种情况:已有结构体定义在.c文件中。 解决办法:将该结构体定义到.h文件中,然后再包含该头文件,或者直接将该结构体定义到当前.c文件中。 #include<stdio.h>#include<stdlib.h>#include<malloc.h>#ifndef __linkedList__H#define__linkedList__H//防止头文件被多次包含#defineMax...
1 结构体 node 是在哪里定义，是否包含了定义 node 的头文件 2 p=(struct node*)malloc(sizeof(char)); /*p为new指针*/ ，应该是 p=(struct node*)malloc(sizeof(node)); /*p为new指针*/ 3 if(head=NULL) head=p; 应该是 head==NULL 吧 ...

Here, an incomplete struct is used as if it is a complete struct, which causes the compiler to throw the error. 1035906452/source.c: In function 'main':1035906452/source.c:6:5: error: dereferencing pointer to incomplete type 'struct round'*x;^~ ...

struct ages才是类型，only是变量名 所以是 int age_search(struct ages *head, int x)
1 开始的定义修改成：typedef struct Node{int ID;struct Node* next;}Node;2 InitList函数 body没有使用，void InitList(Node**head,int n){*head = (Node*)malloc(sizeof(Node));(*head)->next = NULL;(*head)->ID = 1;Node* list = *head;int i;for ( i=1;i<n;i++){Node...
