#include <iostream>
#include <math.h>
using namespace std;
int main ()
{
float x,y,r,x1,y1,distance;
int n,people,out;
cin >> x >> y >> r;
cin >> n;
for (int cnt=1;cnt<=n;cnt++)
{
cin >> x1 >> y1;
distance=sqrt(((y1-y)*(y1-y))+((x1-x)*(x1-x)));
if (r-distance>=0);
}
cout << " " << people << endl;
return 0;
}

`people' is uninitialized
`people' is never modified
