I'm a student stuck on this problem.  The attached short portion of a
C++ program won't let me invoke the constructor in "Var" from main as
long as the class Bexp contains virtual methods.  The error I get points
to the last line and says " undefined reference to Var:Var(char *)"
Almost all of the code is given (I must add to it but can't get past
this problem.  I am not supposed to alter main or workout.  When I
remove the "virtual labels" the constuctor works but "workout" won't.
