Getting a vector into a function that expects a vector<Base*>

Question

Consider these classes.

class Base
{
   ...
};

class Derived : public Base
{
   ...
};

this function

void BaseFoo( std::ve         


        

Answer 1

Instead of passing the container object (vector<>), pass in begin and end iterators like the rest of the STL algorithms. The function that receives them will be templated, and it won't matter if you pass in Derived* or Base*.
