Structure in C - Access value

I am trying to play around with structure and this is what I have: 

  #DEFINE LINEAR 1
  int val;
  struct Item
  {
      double price;
      int weight;
      char Tax;
      int quant;
      int minQuant;
      char namel[30];  
  };

  double totalAfterTax(struct Item item);

 int main() {
   struct Item I[21] = 
   {
     { 4.4,275,8,10,2,"Royal Apples" },
     { 5.99,386,18,20,4,"Melon"},
   };
   val = display(I[0], LINEAR);
   return 0;
 } //main end


   void display(struct Item item, int linear){

   struct Item i1; 
   printf ("%d ", i1.quant); 
   return;
   }

Now, problem is i1.quant is not printing 8 as it is supposed to. I am not sure why?

Please advise?

I think the line below should be removed

struct Item i1;

and you should replace printing line with the following:

printf ("%d \n",item.quant);

According to your program it should give you an error or warning and after making above changes, output should be "10" not 8. As you are printing item.quant.

Inside the display function, you define an 'empty' (uninitialized) struct Item. I believe what you wanted to print should be item.quant:

void display(struct Item item, int linear){
    printf ("%d ", item.quant); 
}
