读取一个整数n ，它最大为25 ，然后读取n 个数的表，并且以逆序打印这个表.

#include <stack>
#include <iostream>
using namespace std;


int main()
    /*Pre:The user supplies an integer n and n decimal numbers.
    Post: The numbers are printed in reverse order.
    Uses: The STL class stack and its methods*/
{
    int n;
    double item;
    stack<double>numbers;   //   deckares and initializes a stack of numbers
    cout <<"Type in a integer n followed by n decimal numbers."<<endl
         <<"The numbers will be printed in reverse order."<<endl;
         cin>>n;
         for(int i = 0;i<n;i++)
         {
             cin>>item;
             numbers.push(item);
         }
         cout<<endl<<endl;
         while (!numbers.empty())
         {
             cout<<numbers.top()<<" ";
             numbers.pop();
         }
         cout<<endl;
