iterators and pointers to lists.

[arathalion]

ok. So i'm having a little problem iterating through a list of mine.

typedef std::list<item*> inventory;

...

//prints the contents of an inventory.
void printInv(inventory* const inv){
        for (std::list<item*>::iterator iter=inv->begin();
                iter <= inv->end; ++iter)
                puts((*iter)->getName());
}

so i want printInv takes a pointer to a constant inventory (std::list<item*>) and then trys to iterate throught it, putting the string returned from the items getName() on the screen.

and i get the error

src/renderer/renderer.cpp: In function ‘void printInv(inventory*)’:
src/renderer/renderer.cpp:31: error: no match for ‘operator<=’ in ‘iter <= ((inventory*)inv)->std::list<_Tp, _Alloc>::end [with _Tp = item*, _Alloc = std::allocator<item*>]’

so in the second line of the for statement its complaining about my use of <=.

if i change it to != then it just complains about 'operator!='.

can someone please tell me what im doing wrong?

thanks in advance.

When dealing with iterators, always use != .
But the reason it is complaining is that end() is supposed to be a method. :-)
