Question

为啥这段代码一直通不过呀，要崩溃了，求指教，万分感谢！

```c
#include<stdio.h>
#include<stdlib.h>
#include<malloc.h>



typedef struct LNode
 {
  int data;  //建了一个整型数据域
  struct LNode *next; //指针域
 }LinkList;
LinkList *p,*q,*head;

LinkList *build(){
     head = (LinkList *)malloc(sizeof(LinkList));
     head->data = 0;
     head->next = NULL;
     int w = 1;
     int i = 0;
     char ch;
     while (w)
     {
          printf("开始输入第%d个数据\n",++i);
          p=(LinkList *)malloc(sizeof(LinkList));
          p->next = head->next;
          head->next = p;
          scanf("%d",&p->data); //输入该节点的数据域内容
          printf("是否继续呢？（y/n）");
          scanf("%c",&ch);
          if(ch == 'n'){
           break;
      }
     }
     head->data = i; //头节点数据域用来记录有多少个节点
     return head;
}

void display(LinkList *head){
 printf("当前链表共有%d个节点\n",head->data);
 q = head->next;
 while (q!=NULL)
 {
  printf("%5d",q->data);
  q = q->next;
 }
 printf("\n");
}
int main(){
 display(build());
 system("pause");
 return 0;
}

31行 scanf("%c",&ch); 之前，加一句 getchar(); 接收前面输入data之后的换行符，否则这个scanf就自动接收换行符了啊
