Question

为什么输入一个字符串之后按回车没有用，还是能输入，怎么搞的？ C语言单向链表

#include<stdio.h>
#include<stdlib.h>
struct stu{
char a;
struct stu *next;
};

struct stu *createlist()
{
char ch;
struct stu *head;
struct stu *t;
head=NULL;
ch=getchar();
while(ch!='\0')
{
t=(struct stu*)malloc(sizeof(struct stu));
t->a=ch;
t->next=head;
head=t;
ch=getchar();
}
return head;
}

void main()
{
struct stu *p,*q;
p=createlist();
while(p)
{
printf("%c\t",p->a);
q=p->next;
free(p);
p=q;
}
return;
}

Answer 1

while(ch!='\0')

换成拦亩这个试试简虚森誉备
while(ch!='\n')
