An electricity board charges the following rates to domestic users to discourage large consumption of energy : For the first 100 units − 50 P per unit Beyond 300 units − 60 P per unit If the total cost is more than Rs.250.00 then an additional surcharge of 15% is added on the difference. Define a class Electricity in which the function Bill computes the cost. Define a derived class More_Electricity and override Bill to add the surcharge.
The topic of this homework is operator overloading. The class ElectronicDevice is given with the corresponding functions as show below. class ElectronicDevice{friend std::ostream& operator<<(std::ostream&, const ElectronicDevice& device_ref);public:ElectronicDevice(const std::string& name_ref, double consumption, double price, bool repairable) : name_(name_ref), consumption_(consumption), price_(price), repairable_(repairable){};double operator+(const ElectronicDevice& rhs_ref) const;double operator-(const ElectronicDevice& rhs_ref) const;ElectronicDevice operator<(const ElectronicDevice& rhs_ref) const;std::string name() const { return name_; };double consumption() const { return consumption_; };double price() const { return price_; };bool repairable() const { return repairable_; };private:std::string name_;double consumption_;double price_;bool repairable_;}; A short main() program is also provided. All necessary libraries have been included.…

Given the Class Definition for ClockType discussed extensively in class, write what would have to be added to the IMPLEMENTATION FILE for the Class ClockType to overload the “= =”, i.e., the comparison “equal-equal sign,” here: That is, write the FULL FUNCTION DEFINITION for THE FUNCTION associated with Class ClockType to overload the “= =” remembering the private members are: b) int hr; // that contains the hours int min; // that contains the minutes int sec; // that contains the seconds
write a program c++ Define a class rectangle with the following data members: L,W and the following memelber functions: 1. Set_data that stores parameters values into data members. 2. Area that returns the area of the rectangle. 3. Ret_Lw that returns the length and width of the rectangle. # Let your main Function declares two objects of the length (L) and the width (W) of the rectangle of largest area.
Consider a class named Calculator with typical four specific functionalities i.e. addition, subtraction, multiplication, and division. Implement these functionalities as four functions with two parameters. It is also required to overload all these functions for int and double data types. In the main function, create an object of class Calculator and invoke its member functions while passing parameters of int and double type.

IN JAVA intends to auto generate test cases for a function foo that has k integers as input arguments, i.e., foo(int n1, int n2, …, int nk). Each argument belongs to a different equivalence class, which are stored in a downloadable Eq.txt file. The content is shown below and may be modified to handle more inputs and equivalence classes. 1, 15; 16, 30 1, 10; 11, 20; 21, 30 1, 5; 6, 10; 11, 15 1, 3; 4, 6; 7, 9; 10, 12 1, 12; 13, 24 For this file, the nth row describes the nth input. Take the second row for example. There are five input arguments. The data 1, 10; 11, 20; 21, 30 indicates that argument n2 has three equivalence classes separated by the semi-colons. Develop an internal method “private int check(int val)” that returns the equivalence class the val is in. The result of check(val = 3) for n2 will be 1 and check(val = 25) for n2 will be 3. Regarding the function foo, it computes the sum of the returned values by the check function for all input arguments. Follow the contents…
Consider the following inheritance hierarchy: class A{ protected: int x, y; public: int z; }; class B: private A{ private: int a, b, c; public: void set(int x, int y, int z, int a, int b, int c); }; Int main(){ Aobja; B objb; } a) If the protected Access specifier in A is changed to public, then how many members of B will be accessed in main() and how? b) Define the function set() without changing its signature as given above. c) Write a default constructor for the class B that does not have an empty parameter list. d) If the data members of A become private, then how they be initialized? e) Add a static data member in class B. Can we use this pointer with static members? If yes how?
