HDU 1065 - I Think I Need a Houseboat

又是恶心人的水题

圆周率取3.1415926就啥事没有..

 #include <iostream>
 #include <cstdio>
 #include <cmath>
 using namespace std;
 double a,b;
 int n;
 int main()
 {
     scanf("%d",&n);
     for(int k=;k<=n;k++)
     {
         for(int i=;i<=n;i++)
         {
             scanf("%lf%lf",&a,&b);
             int ans=(a*a+b*b)*(3.1415926)/;
             printf("Property %d: This property will begin eroding in year %d.\n",k++,ans+);
         }
         puts("END OF OUTPUT.");
     }
 }
