C++ Generic Linked List

Question

For the code below:

#include 
#include 

using namespace std;

class Foo2;
class Foo3;

template 
class Foo1 {
  pub         


        

Answer 1

Combining the bits, it seems like this should work:

int main() {
  std::list > list;
  list.push_back(Foo2());
  list.push_back(Foo3());
  printAll(list); // You'd still need to write this obviously.
  return 0;
}
