With C++ Implement a Complex class and overload the equals (==), not equal (!=), unary minus (-), and right shift operator (>>) for the Complex class. Complex numbers z1=a+bi and z2=c+di are equal if and only if a equals c and bequals d. If z = a+bi is a complex number, -z equals -a-bi. Overload the right shift operator for input.

Create two classes of your choice (a parent and a child) and access their properties as shownabove.

Write an oop program to represent(average function) as friend function between two classes (positive class and negative class)

Write a C++ a class definition for an abstract data type called Graph that models anundirected graph. Some implementation details: Create code for a .cpp file with main function and code for a .h file with classes • Loops are allowed but multiple edges are not allowed.• Vertices are labeled by number from 0 to n-1 where n is the number of vertices in thegraph.Implement the following public member functions.• A constructor that creates an empty graph.• An appropriate destructor.• void load(char *filename): Creates the graph using the file passed into thefunction. The format of the file is described later. You may assume load is only calledonce for a graph. • void display(): Displays the graph's adjacency matrix to the screen.• void displayDFS(int vertex): Displays the result of a depth first searchstarting at the provided vertex. When you have a choice between selecting two vertices,pick the vertex with the lower number.• void displayBFS(int vertex): Displays the result of a breadth…

Implement in C Programing 7.10.1: LAB: Product struct Given main(), build a struct called Product that will manage product inventory. Product struct has three data members: a product code (string), the product's price (double), and the number count of product in inventory (int). Assume product code has a maximum length of 20. Implement the Product struct and related function declarations in Product.h, and implement the related function definitions in Product.c as listed below: Product InitProduct(char *code, double price, int count) - set the data members using the three parameters Product SetCode(char *code, Product product) - set the product code (i.e. SKU234) to parameter code void GetCode(char *productCode, Product product) - return the product code in productCode Product SetPrice(double price, Product product) - set the price to parameter product double GetPrice(Product product) - return the price Product SetCount(int count, Product product) - set the number of items in inventory…

Define the class RectangularCube in C++. A RectangularCube has three sides length(L), width (W), and Height (h), define the sides as private data fields. Include a no-argument constructor that sets all three sides to 1. The class must also have a constructor that receive parameters to initialize sides of the RectangularCube. Include get and set functions for all three data fields. Finally define the functions volume () and surfaceArea () in the class RectangularCube that use the formulas given below to calculate and return the volume and the surface area of the RectangularCube. Give the UML diagram of the class, you may use the MSOffice/Visio to create the UML class diagram (best to download and use Visual paradigm tool, or any other free UML tool). Implement the class using separate files for definition and implementation, use inclusion guard to avoid duplicate code. Make sure to include at least one inline function implementation. Do not Implement the volume () and the SurfaceArea…
