Consider the following C code.
#include <stdio.h>
#include <math.h>
void main()
{

         double pi = 3.1415926535;
         int a = 1;
         int i;

  for(i = 0; i <3; i++)
         if(a = cos(pi * i/2) )
                         printf("%d ",1);
         else printf("%d ", 0);
}
What would the program print?

A

0 0 0

B

0 1 0

C

1 0 1

D

1 1 1
