LINKED LIST question C++ ...Can we make TWO different node types in one program? -

-

i have project finish off regarding linked lists. wanted know if possible write in 2 struct nodetype codes create 2 nodes. if how , should place them? code going contain of 1 node type "videos" in list. , node type "customer" details in list.

i plan use functions every other operation enable program do. wanted know code making 2 nodes , how , should specify these nodes when make functions them?(such inserting new video video node , inserting video customer node(showing rented video) etc etc)...

can please explain code's details can understand it?

because instantiation of class template yields new type, can make list node template:

template<class tag> struct listnode {     listnode *prev, *next; };

and derive multiple times same template instantiating different tag type:

struct videotag; struct customertag;  struct item      : listnode<videotag>     , listnode<customertag>  {};

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

(the array 7 rows 9 columns, btw). mov cx, 7; cx = number of rows outer: ; outer loop walk through rows push cx mov cx, 9 mov row, cx ;rows middle: ; middle-loop walk through columns push cx sub cx, 1 ;cx = cx-1 mov column, cx ;columns inner: ;inner loop - compare , exchange column values cmp marray[row*9 + column], marray[row*9 + column+1] xchg marray[row*9 + column+1], marray[row*9 + column] ; compare , exchange values marray table inc column loop inner pop cx loop mid...
