Summing 100 data values

#include <stdio.h>

int main()

  double data[100];
  double sum = 0.0;
  int i = 0;
  double sign = 1.0;

  printf("\nYou entered the values:\n");
  for(i = 1 ; i<=100 ; i++){
    data[i-1] = 1.0/(2*i*(2*i+1)*(2*i+2));
  }

  for(i = 0 ; i<100 ; i++)
  {
    sum += sign*data[i];
    sign = -sign;
  }
  printf("\nResult is %.4lf\n", 4.0*sum+3);
