Why my program got CE?
// Timus 1020
#include "iostream.h"
#include "math.h"
void main()
{
int i,n;
double r,L,x[100],y[100];
cin>>n>>r;
for (i=1;i<=n;i++)
{ cin>>x[i]>>y[i];}
x[0]=x[n]; y[0]=y[n];
L=0;
for (i=0;i<n;i++)
{ L+=(sqrt(pow(x[i]-x[i+1],2)+pow(y[i]-y[i+1],2)));
}
L+=2*r*M_PI;
cout.precision(2);
cout<<L;
}

Thanks.
But there isn't this problem.
