and this is my program code:

#include <stdio.h>

{
    float a = 1, b = n;

    int i = 1000;
    while (i--) {
        a = (a+b)/2;
        b = n/a;
    }

    return a;
}

int main()
{

    float nail_radius;
    fscanf(stdin, "%d %f", &nail_num, &nail_radius);

    struct fcoord * nail = (struct fcoord *) malloc(sizeof (struct fcoord) * nail_num);
    for (i = 0; i < nail_num; i++)
        fscanf(stdin, "%f %f", &(nail[ i ].x), &(nail[ i ].y));

    float rope_lenght = 0, a, b;

    rope_lenght += (2 * PI * nail_radius);
