刚才的有点问题，这个可以了，不过输入不能为相同的数字等我再该下 #include"stdio.h" #include<malloc.h> typedef struct node { int data; struct node *next; }NODE; int x,i; NODE *creat() { NODE *head,*p,*s; int x; head=(NODE*)malloc(sizeof(NODE)); p=head; printf("输入整数,以0标志结束\n"); scanf("%d",&x); while(x!=0) { s=(NODE*)malloc(sizeof(NODE)); s->data=x; p->next=s; s->next=NULL; p=s; scanf("%d",&x); } p->next=NULL; p=head; head=head->next; free(p); return head; } NODE * delete(NODE *head,int x) { NODE *p,*q; if(head==NULL) printf("链表下益\n"); if(head->data==x) { p=head; head=head->next; free(p); } else { q=head; p=head->next; while(p!=NULL&&p->data!=x) if(p->data!=x) { q=p;p=p->next; } if(p!=NULL) { q->next=p->next; free(p); } else printf("没找到\n"); } return head; } main() { NODE *hea,*p; hea=creat();p=hea; while(p!=NULL) { printf("%d ",p->data); p=p->next; } printf("输入要删除的节点:"); scanf("%d",&x); p=delete(hea,x);

while(p!=NULL) { printf("%d ",p->data); p=p->next; } ;getch(); }

q=head; p=head->next; while(p!=NULL){ while(p!=NULL&&p->data!=x) if(p->data!=x) { q=p;p=p->next; } if(p!=NULL) { q->next=p->next;r=p;p=p->next; free(r); } else printf("没找到\n"); } return head; } main() { NODE *hea,*p; hea=creat();p=hea; while(p!=NULL) { printf("%d ",p->data); p=p->next; } printf("输入要删除的节点:"); scanf("%d",&x); p=delete(hea,x);

----------------解决方案--------------------------------------------------------

#include"stdio.h"

typedef struct node { int data; struct node *next; }NODE; NODE *creat() { NODE *head1,*p,*s; int a; p=(NODE*)malloc(sizeof(NODE)); head1=p; printf("Input the number a:\n"); scanf("%d",&a); while(a!=0) { s=(NODE*)malloc(sizeof(NODE)); s->data=a; p->next=s; p=s; scanf("%d",&a); } p->next=NULL; return head1; } void delete(NODE *head,int x) { NODE *p,*q,*s; if(head==NULL) printf("error!\n"); else { q=head;p=head->next; while(p!=NULL) { if(p->data==x) { s=p; p=p->next; q->next=p; free(s); break; } q=p; p=p->next; if(p->next==NULL) { printf("can't find x\n"); break; } } } } void main() { int x; NODE *head,*p; head=creat(); printf("Input the number x which you want to delete:"); scanf("%d",&x); delete(head,x); p=head; while(p->next!=NULL) { printf("%d ",p->next->data); p=p->next; } getch(); } 这样应该可以了。
