void List_sort (struct nodeStruct **headRef){
struct nodeStruct *tempNode = *headRef;
struct nodeStruct *nextNode, *smallestNode;
while (tempNode != NULL){
nextNode = tempNode->next;
smallestNode = tempNode;
while (nextNode != NULL){
if (nextNode->item < smallestNode->item) {
smallestNode = nextNode->next;
}
nextNode = nextNode->next;
}
int tempInt = tempNode->item;
tempNode->item = smallestNode->item;
smallestNode->item = tempInt;
tempNode = tempNode->next;
}
}
不知道它为什么会产生seg错误,因此不应该编辑NULL。
Segmentation fault. 0x00000000004008d4 in List_sort (headRef=0x7fffffffe458) at list.c:130 130 tempNode->item = smallestNode->item;
任何人都知道为什么要这样做?
更新 执行了建议而没有更多的seg错误,但是没有正确排序。

答案 0 :(得分:1)
这是不对的:
if (nextNode->item < smallestNode->item) {
smallestNode = nextNode->next;
}
它应该是:
if (nextNode->item < smallestNode->item) {
smallestNode = nextNode;
}
