程序代码：

#include<iostream>
using namespace std;

int main()
{  
   const int MAX=100; 
   float f_var[MAX]={0};
   double sum=0.0;
   for (int i=0;i!=MAX;++i)
   {
     cin>>f_var[i];
     sum+=f_var[i];    
   }
   float avg=sum/MAX;
   cout<<avg<<endl;
   for (int i=0;i!=MAX;++i)
   {
     cout<<(f_var[i]-avg>0?f_var[i]-avg:-(f_var[i]-avg))<<" ";
     if (i%10==0) cout<<endl;    
   }  
   return 0;   
}
