本人新手，自己编的代码，但是为什么不能输出结果？求大牛指点！急急急！！感激不尽哈
#include<stdio.h>
#include<stdlib.h>
typedef int Elemtype;
#define M 100
typedef struct
{
    Elemtype data[M];
    int top;
}sqstack;
void Initsqstack(sqstack *&s)
{
    s=(sqstack *)malloc(sizeof(sqstack));
    s->top=-1;
}
bool stackEmpty(sqstack *s)
{
    return(s->top==-1);
}
bool push(sqstack *&s,Elemtype e)
{
    if(s->top==M-1)
        return false;
    s->top++;
    s->data[s->top]=e;
    return true;
}
bool pop(sqstack *&s,Elemtype &e)
{
    if(s->top==-1)
    return false;
    e=s->data[s->top];
    s->top--;
    return true;
}
int main()
{
    Elemtype e,n;
    sqstack *st;
    scanf("%d",&n);
    st=(sqstack *)malloc(sizeof(int));
    if(st==NULL)
        return 0;
    Initsqstack(st);
    while(e!=0)
    {
        push(st,e=n%2);
        n=n/2;
    }
    while(e!=0)
    {
        pop(st,e=n%2);
        n=n/2;
        printf("%d",e);
        }
    }

为了练习栈的基本操作

我已经懂了~~~
