Define a class for the marks (student subject marks) that includes the following data members: A (OOP) B (Data Structures) C (Calculus II) The class also contains the following member functions: Insertion function – to get three values (courses). Sum - to sum up three values (courses). Ave – to give average of the three values (courses). Display function - to display sum and average. NOTE:subject: object oriented programming(oop) Deptt:CS/IT

Q2\B\ True or false ( answer three) 1- Abstract data types cannot be implemented in procedural languages such as C and Pascal. 2- Although methods and fields can be static, constructors cannot be static. 3- One problem with OOP when create a Class it can never be changed. 4- polymorphysim is extensively used in implementing inheritance.

LANGUAGE : C++ QUESTION :  make a  class of Student with attributes StudentName, Enrollment, semester, section, course MarksObtained and Grade. Write appropriate constructors, get and set functions for data members. The data member grade is automatically calculated based on marks obtained out of 100 for each course. also print out the outputs

SUBJECT: OOPPROGRAMMING LANGUAGE: C++ ALSO ADD SCREENSHOTS OF OUTPUT.   Write a class Distance to measure distance in meters and kilometers. The class should have appropriate constructors for initializing members to 0 as well as user provided values. The class should have display function to display the data members on screen.   Write another class Time to measure time in hours and minutes. The class should have appropriate constructors for initializing members to 0 as well as user provided values. The class should have display function to display the data members on screen.   Write another class which has appropriate functions for taking objects of the Distance class and Time class to store time and distance in a file.   Make the data members and functions in your program const where applicable

Write this C++ programme. Add 3 data members to the parent class and 2 to the child class to conduct inheritance. (data members in classes make sense). Parameterized constructors are required in parent classes.  Child class constructors must give values to parent class constructors. Finally, construct a child class object and show its data on the console.

Mark the following statements as true or false. a. In single inheritance, a base class can create only one derived class. (1) b. The public members of a base class can only be inherited as public members in the derived class. (2) c. To redefine (or override) a member function of the base class in the derived class, the corresponding member function must have the same name, number, and type of parameters. (3) d. If the derived class does not override a public member function of the base class, you may specify a call to that public member function by using the name of the function and the appropriate parameter list. (3) e. The constructor of a derived class can specify a call to the constructor of the base class in the heading of the function definition. (4) f. The constructor of a derived class can specify a call to the constructor of the base class using the name of the class. (4) g. Suppose that x and y are classes, one of the member variables of x is an object of type y, and both classes have constructors. The constructor of x specifies a call to the constructor of y by using the object name of type y. (4) h. When the destructor of the derived class executes, it automatically invokes the destructor of the base class. (5) i. The class ios is the base class for all stream classes. (7) j. In protected inheritance, the private members of the base class are protected members of the derived class. (8) k. In composition, one or more members of a class are objects of another class type. (9)

QUESTION 4 (use c++ to answer the following question) Note: You need to add required constructors/destructors, member functions or data members/variables in your program to complete its execution.   Suppose we are designing a record-keeping program that has records for salariedemployees and hourly employees. There is a natural hierarchy for grouping these classes.These are all classes of people who share the property of being employees.Employees who are paid an hourly wage are one subset of employees. Anothersubset consists of employees who are paid a fixed wage each month or week. Although the program may not need any type corresponding to the set of all employees, thinking in terms of the more general concept of employees can be useful. For example, all employees have names, Social Security numbers (ssn) and net pay, and the member functions for setting and changing the name, ssn and netpay would be same for both hourly and salaried employees.   Implement the above mentioned…

OOP Homework Inheritance (PYTHON) 1. Given two classes as described in Customer.py (attached) Revise the class using inheritance to simplify the codes and to remove repetition of codes. Package-delivery services, such as FedEx®, DHL® and UPS®, offer a umber of different shipping options, each with specific costs associated. Create an inheritance hierarchy to represent various types of packages.
