- (ii) By using your own example, declare a class with a static data field together with the accessor to that static data.module 7: suppose corporation is a base class and PublicCorporation is a derived class.Also suppose that each class defines a head() member function, that ph is a pionter to the Corporation type, and that ph is assigned the address of a PublicCorporation object. how is ph->head() interpreted if the base class defines head() as a a. Regular nonvirtual method b. virtual method9.Think of at least one constructors and the fitting mutator and accessor techniques for the class' fields. Exhibit an object of the Client class in a basic program..
- Consider the definition of the class product Type as given in Exercise 8. Which function members are accessors and which are mutators? (4)Suppose that you have the declarations of Exercise 7. Write the definitions of the member functions of the classes circle and cylinder. Identify the member functions of the class cylinder that overrides the member functions of the class circle. (2, 3, 4)Assume the definition of class foodType as given in Exercise 6. Answer the following questions? (1, 2, 3, 5, 6) Write the definition of the member function set so that private members are set according to the parameters. The values of the int and double instance variables must be nonnegative. Write the definition of the member function print that prints the values of the data members. Write the definitions of the member functions getName, getcalories, getFat, getSugar, getCarbohydrate, getPotassium to return the values of the instance variable. Write the definition of the default constructor of the class foodType so that the private member variables are initialized to 0, 0. 0, 0, 0. 0, 0. 0, respectively.
