[LCP]printf Question

[sasidhar p]

Hi,
Can somebody explain me this behaviour, I am all confused....
main()
{
   while(1)
   {
      printf("Hi\n");
      getchar();
   }
}

Out put :

[psasi at jldev 2]$ ./a.out
Hi
a
Hi
Hi
b
Hi
Hi
c
Hi
Hi
d
Hi
Hi

[psasi at jldev 2]$

I am using gcc on Linux 2.2.14
why is the "Hi" getting printed twice...

I tried the following variants, but the o/p pattern is same...
#include <stdio.h>
#include <unistd.h>

main()
{
   char buf[]="Hi\n";
   while (1)
   {
      write(1,buf,3);  /* I tried writing to fd 2 also*/
      getchar();
   }
}
