(a) Draw a class diagram representing the classes declared below (b) Declare these classes in a file entitled "BinaryOperators.h", inserting appropriate pre-compilation directives. Define all the non-abstract methods in a source file entitled "BinaryOperators.cpp". Include also the definition of the function Test0. In this function use polymorphism to compute the following: 3+7, 3-5,3*7,3/5,3/0 (c) Define mainO in a source file entitled "main.cpp". Call TestO in mainO (d) Run you program and turn in the header files, source files, and the output of your program. class Binaryoperator public: BinaryOperator double opl, double op2: fOpl opl, EOp2 op2 virtual double Doop () const - 0; protected: const double EOpl; const double EOp2; II class BinaryOperator class Adder public BinaryOperator ( public: Adder double opl, double op2 virtual double Doop const: Binaryoperator opl, op2 i I/ class Adder class Subtractor public Binaryoperator public: Subtractor double opl, double op2 virtual double DoOp consti Binaryoperator opl, op2 i II class Subtractor class Multiplierpublic BinaryOperator l public: Multiplier double opl, double op2Binaryoperator opl, op virtual double Doop consti II class Multiplier class Divider : public BinaryOperator public: Divider double opl, double op2Binaryoperator opl, op2 virtual double Doop const: i I/ class v void Test
