通过修改链接对链接列表进行排序

我试图通过修改链接而不是交换data.i’m使用选择sort来排序链表。我不知道我哪里出错。我是初学者请帮助我。

struct node { int data; node* link; }; node* p; void sort() { node* temp = p; node* save; node* prev; node* tprev; node* push = new node; tprev = NULL; for (; temp != NULL; temp = temp->link) { push = temp->link; for (; push != NULL; push = push->link) { if (push->datadata) { save->link = temp->link; temp->link = push->link; push->link = save->link; prev->link = temp; tprev->link = push; } prev = push; } tprev = temp; } }

 void sort(){ node *temp, *push; node *tprev, *pprev; node *save; tprev = NULL; for (temp = p; temp != NULL; temp = temp->link){ pprev = temp; for (push=temp->link; push != NULL; push = push->link){ if (push->data < temp->data){ save = temp->link; temp->link = push->link; if(save == push) push->link = temp; else push->link = save; if(pprev != temp) pprev->link = temp; if(tprev) tprev->link = push; else p = push; save = temp; temp = push; push = save; } pprev = push; } tprev = temp; } }
