if you change it so it should compile, but it is not the best way

struct item_info
{
      char *itemname;
      int quantity;
...

You have than the problem that itemname is only a pointer and you need to alloc and free it. And manage it somehow.

I would write an "Setter"

Set(struct *item_info, char*name, ...)
{
 strncpy( item_info->name, sizeof(item_info->name), name);//check length!!!

...
}

Solution 1

You cannot initialise a structure like that at run time. If you are using constant values then you can get the compiler to set it up by coding:

C++

struct item_info
{
      char itemname[15];
      int quantity;
      float retail;
      float wholesale;
      //int quatityonorder;
}item[NOOFITEM] =
{
    {"rice",10,40,30},
    {"sugar",10,40,30},
    {"soap",10,40,30}
};

But if you want to assign values at run time then you have to do it manually like:

C++

strcpy(item[0].itemname, "rice");
item[0].quantity = 10;
item[0].retail = 40;
item[0].wholesale = 30;

What about pointer to the structure?

Richard MacCutchan 19-Aug-14 15:15pm

What?

Maciej Los 19-Aug-14 15:45pm

Is it possible to initiate structure via pointer?
item_info *ii;

Richard MacCutchan 20-Aug-14 3:24am

Sorry, yes of course, you can either use a pointer, incrementing it through the loop, or use the index value. It just takes different syntax, thus:


struct item_info* pInfo = item;
strcpy(pInfo->itemname, "rice");
pInfo->quantity = 10;
// etc
pInfo++; // point to next entry
