incomplete type

technologist (607)
Keep getting the following compile errors.

..\src\main.cpp:36:13: error: field 'card_rank' has incomplete type 'Card_Deck'
Card_Deck card_rank;
^
..\src\main.cpp:37:13: error: field 'card_suit' has incomplete type 'Card_Deck'
Card_Deck card_suit;

I think its something simple, but am at a loss to explain. What's going on here and fix it how?

You can't have Variables of type Card_Deck inside the Card_Deck struct? I mean, what's the logic here?

You are correct. Fixed in this revison but a new one popped up:

\src\main.cpp:46:25: error: invalid conversion from 'int' to 'Card_Rank' [-fpermissive]

I am trying to link an array of structs to card rankings and suits. Error location:

card_ptr[ctr].rank = ctr; in "fill_card_deck function"

int and Card_Rank are two different types. Simply assigning an int to a Card_Rank will not work.

I was going to say you could solve this by adding an explicit cast, or by changing the type of rank to int, but when I look closer i see there are problems with the code other than just what the compilation errors show. You loop ctr from 0 up to 52, so ctr is not really the rank, is it? It looks like you will have to do some calculations on ctr to get the rank and suit out of it.
