- C++ Dynamic Programs Hoskins College offers both curriculum and continuing education courses. Write a program that dynamically tracks these courses using an array of object pointers. Every course (both curriculum and continuing education) has a course id, title, room number, and number of contact hours. A curriculum course has credit hours and tuition rate. Tuition is calculated by multiplying the course's credit hours by tuition rate. A continuing education course has a flat fee (cost). Implement a show() function in every class that displays the data in the object. Part A: Create an inheritance-based collection of classes to represent these different courses. Include code in main to test your work by instantiating objects of the two derived classes. Part B: Modify your program. Remove the objects you created in main to test the classes. Modify the base class so that show() becomes a virtual class. In main, create a single array capable of holding pointers to objects of both…Fractran interpreter def fractran(n, prog, giveup=1000): John Conway, who was quite a character among mathematicians, is best known for The Game of Life, not to be confused with the family board game sharing the same name. That achievement eclipsed basically all other wacky and original creations of Conway, so in the name of fairness, we ought to give his less appreciated creations an occasional turn in the flashing lights of the red carpet fame. This lab has you write an interpreter for the simple esoteric programming language called FRACTRAN, named as a pun of the word “fraction” and the FORTRAN programming language. (Things used to be all in uppercase back in when real scientists wore horn-rimmed glasses and their cars were equipped with tail fins, with occasional dollar signs interspersed as separators to keep the pampered prices of the military-industrial complex happy.) A program written in such mysterious and hard-to-decipher form consists of nothing but a list of positive…Object can’t be used with pointers because they belong to user defined class, and compiler can’t decide the type of data may be used inside the class. a) True b) False
