UC知道能通过编译,但却不能成功运行

#include <stdio.h>
#include <stdlib.h>
typedef struct node
{
char data;
struct node* next;
}stacknode;
typedef struct stack{
stacknode *top;
int length;
}linkstack;
void InitStack(linkstack *s)
{
s->top=NULL;
s->length=0;
}//初始化堆栈
void push(linkstack *S,int value)
{
stacknode *newptr=(struct stacknode *)malloc(sizeof(stacknode));
if (newptr!=NULL) /*如果有可用的内存*/
{
newptr->data=value;
newptr->next=S->top;
S->top=newptr;
}
else printf("%d not inserted. No memory available.\n",value);
}
char pop(linkstack *S)
{
stacknode *temp;
temp=S->top;
char elem=temp->data;
S->top=temp->next;
通不过MS VC++ 编译器。
（1）stacknode *newptr=(struct stacknode *)malloc(sizeof(stacknode));
应当是：
stacknode *newptr=(stacknode *)malloc(sizeof(stacknode));
（2）linkstack *s; s->top=NULL;
s没有初始化，就使用了。
（3）char elem;
scanf("%d",&elem); char 型不能用%d 格式
要么改成 unsigned char elem
要么改成 %s
我用DEV C++跟VC++ 6.0测试,也不能通过编译
Compiling...
