Thread: error with simple printf statement

Hi guys,

I tried debugging my programme with a printf statement. But it gives me the following error:tutorial_9_qn3.c:37: error: parse error at end of input. Can you please advise what's wrong?

Code:

1 #include <stdio.h>

  4 struct money {int id; int value; int weight; double valuePerWeight;};

  7 int totalItems(struct Item items[]);
  8 void takemore (struct Item items[], struct money worth[], int numItems);
  9 void sort(struct money worth[], int numItems);
 10 void printItems ( struct Item items[], int numItems);
