problem with displaying doubles in array

ok during this program whenever i try to display this "inventory" i get a string of numbers that doesnt match the numbers inputted...

heres the structure for the inventory

Code:

---

typedef struct
  {
  int  day;
  int  month;
  int  year;
  } DATE_S;

typedef struct
  {
  char    bname[MAXN];  /* brand name  */
  char    bcomp[MAXN];  /* bottling company */
  int    qty;          /* quantity in stock */
  double    cost;        /* the current cost of the item */
  DATE_S  date;        /* the date of the last shipment */
  double    price;        /* the selling price of the item */
  } ITEM_S;

---

heres the function for adding the inventory:

Code:

---

void  add_new_item(ITEM_S items[], int *pnitem)
{
ITEM_S  *pnew;
char    *p;
char    buf[MAXN];


if ( *pnitem >= MAXITEMS )
  {
  printf("Out of memory [ Max items in list %d]\n", MAXITEMS);
  return;
  }

pnew = &items[*pnitem];


/* 1 */
for ( ; ; )
  {
  printf("Enter brand name [Enter to abort] \n");
  if ( fgets(pnew->bname, MAXN, stdin) == NULL )
      return;
  if ( pnew->bname[0] == '\n' )
      return;
  if ( p = strrchr(pnew->bname, '\n') )
      *p = '\0';
  if ( find_item_in_list(items, *pnitem, pnew) )
      printf("Brand name already in list\n");
  else
      break;
  }

/* 2 */
printf("Enter bottling company\n");
fgets(pnew->bcomp, MAXN, stdin);
if ( p = strrchr(pnew->bcomp, '\n') )
  *p = '\0';

/* 3 */
printf("Enter quantity in stock\n");
fgets(buf, MAXN, stdin);
pnew->qty = atoi(buf);

/* 4 */
printf("Enter the current cost of the item\n");
fgets(buf, MAXN, stdin);
pnew->cost = atoi(buf);

/* 5 */
printf("Enter the selling price of the item \n");
fgets(buf, MAXN, stdin);
pnew->price = atoi(buf);

/* 6 */
printf("Enter the day of the last shipment \n");
fgets(buf, MAXN, stdin);
pnew->date.day = atoi(buf);

printf("Enter the month of the last shipment \n");
fgets(buf, MAXN, stdin);
pnew->date.month = atoi(buf);

printf("Enter the year of the last shipment \n");
fgets(buf, MAXN, stdin);
pnew->date.year = atoi(buf);

++*pnitem;

printf("\n\n");
}

---

heres the function for displaying the code...

Code:

---

void  print_list(ITEM_S items[], int nitem)
{
int  i;


if ( nitem == 0 )
  printf("The list is empty\n\n");
else
  for ( i = 0 ; i < nitem ; ++i )
      printf("%8s %8s %4d %2d %2d %d/%d/%d\n",
          items[i].bname, items[i].bcomp, items[i].qty, items[i].cost,items[i].price,
          items[i].date.day,
          items[i].date.month,
          items[i].date.year);   
printf("\n");
}

anybody know why the numbers arent saving correctly?

Use atof instead of atoi to convert a string to double

Try %f instead of %d to printf a double

(%lf to scanf a double)

for the item[i].cost and item[i].price i still dont get doubles... ='(

Use sscanf(), with %lf. Remember printf() takes %f.

how would that look in code.. i dont really know how to use sscanf with this function.. sry...

Well, look it up on google. The first hit for "sscanf" is this: http://www.cplusplus.com/ref/cstdio/sscanf.html

Use something like this:

Code:

---

sscanf(buffer, "%lf", &adouble);
