Question

I have a program where the user is prompted to either list inventory, search inventory, or enter inventory. In the main program parts is declared as: inventory parts[num], where num is defined as 5.

The getInventory() function works fine. However i cannot get the displayInventory function to work when passing "parts". The function HAS to be passed (inventory parts, int num).

I also need a function to search inventory, also passing (inventory parts, int num)

#ifndef _INVENTORY
#define _INVENTOR
#include <stdio.h>




typedef struct INVEN
{
char PN [7];
char DES[165];
char MAN [4];
double cost;
double price;
int qty;
int reo;} inventory;



//prototypes
void getInventory(inventory *, int);
void displayInventory(inventory, int);
void ignor_to_nl(void);

#endif


void getInventory (inventory *parts, int num)
{

inventory *part;
part=parts;


printf("Enter the part number (up to 6 characters): ");
scanf(" %6[^ ]", part->PN);
ignor_to_nl();

printf("Enter the description (up to 15 characters): ");
scanf(" %15[^ ]", part->DES);
ignor_to_nl();

printf("Enter the manufacturer code (up to 3 characters): ");
scanf(" %3[^ ]", part->MAN);
ignor_to_nl();

printf("Enter the cost: ");
scanf("%lg", &(part->cost));
ignor_to_nl();

printf("Enter the price: ");
scanf("%lg", &(part->price));
ignor_to_nl();

printf("Enter the qty on hand: ");
scanf("%i", &(part->qty));
ignor_to_nl();

printf("Enter the reorder level: ");
scanf("%i", &(part->reo));
ignor_to_nl();

puts("");

return;
}

//function to display inventory
//parameters must be (inventory parts, int num)

void displayInventory(inventory part, int num)
{



printf("Part number: %s ", part.PN);
printf("Part description: %s ", part.DES);
printf("Part manufacturer: %s ", part.MAN);
printf("Cost $%6.2f selling price: $%6.2f "
" ", part.cost, part.price);
printf("Quantity %i reorder level %i ", part.qty, part.reo);

return;
}



//function to search inventory
//parameters must be (inventory parts, int num)

void searchInventory (inventory parts, int num)
{


}


void ignor_to_nl(void)
{
while(getchar()!=' ');
return;
}
