1. Draw a call graph describing program ScoreAverager. Each node in the graph is a class (and main() is a node in the graph), and an edge from class A to class B means that A uses B.
2. Draw a call graph describing program ScoreAverager. In this call graph each node is a method, and an edge from method A to method B means that A invokes B.
   • Show only the static information available at compile time (static class, not dynamic class).
   • Remember the constructor/destructor chaining that happens with inheritance (including interface implementation).
   • Remember that for statically allocated vars (e.g. scheduler in main()), the constructor and destructor are implicitly called when entering and exiting the scope in which they are declared.
