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;^~ ...

gcc编译出现:error: dereferencing pointer to incomplete type 使用gcc编译c文件出现如下错误:getIP.c:14: warning: implicit declaration of function ‘gethostname’ getIP.c:20: warning: implicit declaration of function ‘getaddrinfo’ getIP.c:21: error: dereferencing pointer to incomplete type getIP....
你这段代码问题可多了 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 p=...
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...
tcpclient.c:59:46: error: dereferencing pointer to incomplete type 源码是: // set params of sockaddr_in instances serv_addr.sin_family = AF_INET; serv_addr.sin_port = htons(PORT); serv_addr.sin_addr = *((struct in_addr*)host->h_addr); ...
The name of the array is a pointer to the first element of the array. printf("%s",pntr)(NOTE %s) treats the pointer to char as a string pointer and will output all the char's till it finds a \0. In other words in the two statements below pntr and array are both p...
编译c时提示“dereferencing type-punned pointer will break strict-aliasing rules”如何处理? 1. 示例如下: char my_array[10]; *(int *)my_array = 0xaabbccdd; 2. 修改如下即可解决此问题: char my_array[10]; int tmp = 0xaabbccdd; memcpy(my_array, &tmp, sizeof(tmp));...
struct ages才是类型，only是变量名 所以是 int age_search(struct ages *head, int x)
