However it should have its own methods such as square root.arrow_forward#include void main(void) { int c =2 ^3; cout<< c; }arrow_forward
- Course: Object Oriented programming Lnaguage: C++ You have to solve the Make the program correctly and in 2 hours. kindly Make program correct as much as you can. Question: Develop a polymorphic banking program using the Account hierarchy in which two types of Accounts can be created i.e.Current Account and Saving Account respectively. Each account must have to give the interest to the bank depending upon their account type. A function of name InterestRate() will calculate the interest of account and returns the interest amount. Current Account has annual interest rate of 0.1% of actual amount and SavingAccount will have to pay interest rate of 1.0% of actual amount. Also write a main function for polymorphic calls of the functions. Note: Polymorphic calls for the functions are necessary. Necessary constructor, Destructors, setters, getters and other functions should also be defined.arrow_forwardC++ Functions provide a means to modularize applications Write a function called "Calculate" takes two double arguments returns a double result For example, the following is a function that takes a single "double" argument and returns a "double" result double squareArea(double side){ double lArea; lArea = side * side; return lArea;}arrow_forwardSTRUCTURES IN C The circle has two data members, a Point representing the center of the circle and a float value representing the radius as shown below. typedef struct{ Point center; float radius;} Circle; typedef struct{ int x; int y;}Point; Implement the following functions:a. float distance (Line l1);- computes and returns the distance between the two points of the line.distance = sqrt((x2-x1)^2+(y2-y1)^2) b. float diameter(Circle circ);- computes the diameter of a circle.arrow_forward

- Problem description: in C++ (Malik,2017) Programming Exersices Problem 16, pág. 740, Cap 10 Write the definition of a class, swimmingPool, to implement the properties of a swimming pool. Your class should have the instance variables to store the length (in feet), width (in feet), depth (in feet), the rate (in gallons per minute) at which the water is filling the pool, and the rate (in gallons per minute) at which the water is draining from the pool. Add appropriate constructors to initialize the instance variables. Also add member functions to do the following: determine the amount of water needed to fill an empty or partially filled pool, determine the time needed to completely or partially fill or empty the pool, and add or drain water for a specific amount of time. Changes to do. Design a class, where its attributes are pointers Implement the copy constructor member function. Implement the waterfall effect, when entering the information. Use the this pointer to access the…arrow_forwardAssignment: Class, Constructors, Destructors 1. Write a c++ program that uses <iostream> that has a class staff having fields: Staff_id , name, salary.
