我是想用链表来存放一串字符的啊，为什么通不过呢？？

#include"stdio.h" #include"malloc.h" struct string { char a; char *next; }; void main() { struct string *p1,data; char *p; p1=&data; p=(char*)malloc(sizeof(struct string)); p1->next=p; printf("please Enter the string."); scanf("%c",p1->a); if(p1->a!='\n') { p=(char *)malloc(sizeof(struct string)); p1->next=p; scanf("%c",p1->a); } else p1->next=NULL; }

改成结构体了还是不行啊！！

#include"stdio.h" #include"malloc.h" #include"string.h" #define getnode(type) (type*)malloc(sizeof(type)) struct string { char a; struct string *next; }; void main() { struct string *top,*p; char c; top=NULL; while((c=getchar())!='\n') { p=getnode(struct string); p->a=c; p->next=top; top=p; } //top=top->next; while(top) { p=top; putchar(p->a); top=top->next; free(p); } }

改成这样就好多了，把输入的字符逆序放在链表里，还可以输出来啊，呵呵！谢谢各位了！！
