Exercise 7a

Objective:

In your team, explain why the compiler won't allow the second call in the C++ code section below. Give an example of bad things that could happen if the compiler did allow the second call.

C++ code section:

#include <list>

using std::list;

class foo { ...

class bar : public foo { ...

static void print_all(list<foo*> &L) { ...

list<foo*> LF;

list<bar*> LB;

...

print_all(LF); // works fine

print_all(LB); // static semantic error

Submitting your solution:

You may write submit your solution as a textual narrative explanation with possible code output for illustration. Since this is a group assignment, write each team member's name along with "Exercise 7a" on your solution.
