C Puzzles

In this site, there is a bunch of C programming questions. Enjoy!

First puzzle:

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<stdio.h>
#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("%dn",array[d+1]);
      return 0;
  }

Find out what’s going wrong.
