实在是不清楚为何，输入字符串后，就不在输出了？出现了什么问题？#include<stdio.h>#include<stdlib.h>#include<malloc.h>struct List{ char ch; List *next;};struct List *creat(){ List *head,*p1,*p2; char n; int i=0; head=NULL; printf("输入字符串:\n"); n=getchar(); while(n!='\n'); { p1=(List *)malloc(sizeof(List)); p1->ch=n; if(i==0) { i++; head=p1; } else p2->next=p1; p2=p1; n=getchar(); } p2->next=NULL; printf("字符串已完全存入链表\n"); return (head);}int main(){ List *head,*p1,*p2; char n; head=creat(); printf("输入的字符串为:\n"); n=getchar(); return 0;}
