要求在每次调用中，在单独的一行中显示输入结果并且增加一级缩进
#include<iostream>
#include<iomanip>
using namespace std;
unsigned long jiecheng(unsigned long);
int main()
{
    for(int counter=0;counter<=10;counter++)
    {
          cout<<setw(2)<<counter<<"!="<<endl;
          int count=5,num=counter;
          while(num>=2&&num<=10)
          {           
               cout<<setw(count)<<num<<"*"<<num-1<<"!"<<endl;
               count+=2;
               num--;           
          }
          cout<<setw(count+2)<<"="<<jiecheng(counter)<<endl;
    }      
    system("pause");
}
unsigned long jiecheng(unsigned long number)
{
         if(number<=1)
         {
           return 1;
         }  
         else
         {  
            return number*jiecheng(number-1);
         }
