我试图写一个抽象的数据类型来表示使用链表的整数项集。
我收到以下错误:
ERROR undeclared identifier 'linkedListSet'
error #2152: Unknown field 'code' of '(incomplete) struct LinkedListSet'.
并且觉得我一定在打破一些关于函数,结构和指针的基本规则,但是我真的不明白。下面是我的代码,其中注释了错误消息行。
#include<stdio.h>
#include<stdlib.h>
struct linkedListElement{
int data;
struct linkedListElement * next;
};
struct linkedListSet {
//struct linkedListElement * firstElement;
struct linkedListElement * header;
struct linkedListElement * current;
struct linkedListElement * temp;
int code;
};
struct linkedListSet * createdSet (){
struct linkedListSet * newSet = malloc(sizeof(linkedListSet));
//ERROR undeclared identifier 'linkedListSet'
newSet->header->data = 0;
newSet->header->next = NULL;
return newSet;
}
int addItem (struct LinkedListSet * setPtr, int info){
struct linkedListElement * newElementPtr;
setPtr->code = 3;
//error #2152: Unknown field 'code' of '(incomplete) struct LinkedListSet'.
return 1;
};
int main(){
return (0);
最佳答案
linkedListSet
应为struct linkedListSet
:
struct linkedListSet * newSet = malloc(sizeof(struct linkedListSet));
LinkedListSet
应该是linkedListSet
。int addItem (struct linkedListSet * setPtr, int info)
关于c - C套链表(抽象数据类型),我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/19840070/
