Thread: Struct with a ptr to a dynamically allocated array of other structures :(

Well, that's where I'm stuck. I dynamically allocate (with calloc) the space needed for my array of country structures:

Code:

db->list = (struct Country *)calloc( countries, sizeof( struct Country ) );

After that, I don't really know how to work with that array anymore. I've never read or used anything that does this. Sorry

Some of the code provided by my teacher makes me doubt what I'm doing (not that I was ever sure):

Code:

	for( i = 0; i < db->ncountries; i++ )
	{
		delete_country( db->list+i );   // free mem alloc to a country
	}

I should be able to use that same "db->list+i" part to check the array, right? I'm just trying to find the first free element to insert my country into...
Data structures are so much easier, but I'm stuck with these parameters!

After that, I don't really know how to work with that array anymore. I've never read or used anything that does this

But anyway , using calloc , the space is initializied to zero.

to loop the array :

Code:

int  i;

for( i = 0; i < db->ncountries; i++ )
    db->list[i] = NULL;
    /* or
    *(db->list+i) = NULL;
    */

Why don't u post the all code ?
