C Puzzles

1.The expected output of the following C program is to print the elements in the array. But when actually run, it    doesn't do so.
   #include
   #define TOTAL_ELEMENTS (sizeof(array) / sizeof(array[0]))
   int array[] = {23,34,12,17,204,99,16};
   int main()
   {
   int d;
   for(d=-1;d <= (TOTAL_ELEMENTS-2);d++)
   printf("%d\n",array[d+1]);
   return 0;
   }
Find out what's going wrong.

2.I thought the following program was a perfect C program. But on compiling, I found a silly mistake. Can you find it out (without compiling the program :-) ?
#include

void OS_Solaris_print()
{
printf("Solaris - Sun Microsystems\n");
}

void OS_Windows_print()
{
printf("Windows - Microsoft\n");

}
void OS_HP-UX_print()
{
printf("HP-UX - Hewlett Packard\n");
}

int main()
{
int num;
printf("Enter the number (1-3):\n");
scanf("%d",&num);
switch(num)
{
case 1:
OS_Solaris_print();
break;
case 2:
OS_Windows_print();
break;
case 3:
OS_HP-UX_print();
break;
default:
printf("Hmm! only 1-3 :-)\n");
break;
}

return 0;
}

3.What's the expected output for the following program and why?
enum {false,true};

int main()
{
int i=1;
do
{
printf("%d\n",i);
i++;
if(i < 15)
continue;
}while(false);
return 0;
}
