给定程序中,函数fun的功能是将不带头结点的单向链表结点数据域中的数据从小到大排序。即若原链表结点 数据域从头至尾的数据为10,4,2,8,6,排序后链表结点数据域从头至尾的数据为2,4,6,8,10。 #include #include #define N 6 typedef struct node { int data; struct node *next; } NODE; void fun(NODE *h) { NODE *p, *q; int t; p = h; while (p) { q = p->next ; /**********found**********/ while (______) { if (p->data > q->data) { t = p->data; p->data = q->data; q->data = t; } q = q->next; } p = p->next; } } NODE *creatlist(int a[]) { NODE *h,*p,*q; int i; h=NULL; for(i=0; i { q=(NODE *)malloc(sizeof(NODE)); q->data=a[i]; q->next = NULL; if (h == NULL) h = p = q; else { p->next = q; p = q; } } return h; } void outlist(NODE *h) { NODE *p; p=h; if (p==NULL) printf("The list is NULL!\n"); else { printf("\nHead "); do { printf("->%d", p->data); p=p->next; } while(p!=NULL); printf("->End\n"); } } main() { NODE *head; int a[N]= {0, 10, 4, 2, 8, 6 }; head=creatlist(a); printf("\nThe original list:\n"); outlist(head); fun(head); printf("\nThe list after inverting :\n"); outlist(head); }
