利用栈将输入的十进制数及一些基本的栈操作

import java.io.BufferedReader;

import java.io.InputStreamReader;
import java.util.Stack;

  int temp=Integer.parseInt(strin.readLine());
  do{
  //用堆栈 10 % 2 把余数压入堆栈后 再弹出
  stk.push(temp%2);
  temp=temp/2;

  }while(temp!=0);
  while(!stk.empty()){

/*一些对栈的基本操作

#define StackSize 100
typedef int ElemType;
typedef struct{
            ElemType  data[StackSize];
            int top;
}SqStack;
/*初始化
void  InitStack(SqStack *s)
{
  s->top=-1;
}
*/
/*压栈
int push(SqStack *s,ElemType e)
{
  if(s->top<StackSize-1)
  {
     s->top=s->top+1;
     s->data[s->top]=e;
     return 1;
  }
  else
  {
     printf("overflow!/n");
     return 0;

/*出栈

ElemType pop(SqStack *s)
{
  ElemType e;
  if(-1==s->top)
  {
     printf("underflow/n");
