Questions related to C#. When you build a class in C#.NET, how many sub classes can inherit from the class that you just built? In Object Oriented Development, there are 3 primary concepts that define Object Oriented Programming. What are these concepts? Function/Method Overloading is when you build 2 or 3 functions with the same name but different argument lists. T/F?

You must alter the Queue class you created in L5 to make it a CIRCULAR Queue class . Call your class Queue. it must be a template class. public class Queue <T>{ } I have put a driver program in the module . It is called CircularQueue.java This driver program should then run with your Queue class (no modifications allowed to the driver program). Your Queue class should have at least the following methods: one or more constructors, enqueue, dequeue,...

Here is a C++ class definition for an abstract data type LinkedList of string objects. Implement each member function in the class below. Some of the functions we may have already done in the lecture, that's fine, try to do those first without looking at your notes. You may add whatever private data members or private member functions you want to this class. #include #include typedef std::string ItemType; struct Node { ItemType value; Node *next; }; class LinkedList { private:...

Create a c++ class called Fraction in which the objects will represent fractions. Remember: do not reduce fractions, do not use "const," do not provide any constructors, do not use three separate files. You will not receive credit for the assignment if you do any of these things. In your single file, the class declaration will come first, followed by the definitions of the class member functions, followed by the client program. It is required that you provide these member...

c++ The above Account class was created to model a bank account. An account has the properties (keep the properties private) account number, balance, and annual interest rate, date created, and functions to deposit and withdraw. Create two derived classes for checking and saving accounts. A checking account has an overdraft limit, but a savings account cannot be overdrawn. Define a constant virtual toString() function in the Account class and override it in the derived classes to return the account...

Hello, I need this is C++. Thank you! (1B) Write a Fraction class whose objects will represent Fractions. Note: this is the first part of a multi-part assignment. For this week you should not simplify (reduce) fractions, you should not use "const," and all of your code should be in a single file. In this single file, the class declaration will come first, followed by the definitions of the class member functions, followed by the client program. You must provide...

please do this in C++! I want to understand it, it must be done before the evening or nightime. Follow instructions exactly as it says. Please send a screenshot also with your code so I can see how it is supposed to be formatted. Since typing it a chegg answer, makes it look a bit messy. Your program will read in a file of commands.
