c++ - Limitations on pointers to various types within a class family? -


suppose have 4 classes: a,b,c, , d.

a base class. b derived a. c derived a.

d derived b.

i have vectors of each type of object.

i create 5th class excluded related classes (family?), called z. z contains variable points object of class a, called purple.

can create "inter-family" universal pointer doing like: * puniversal;

and point puniversal a,b,c, or d interchangeably object stored in vector of type.. set purple variable of z puniversal?

yes, can that. it's 1 of main benefits of having derived classes.

if have functions in a should implemented b or c, make sure they're virtual.
