- MindTap: In C#, Write a program named Averages that includes a method named Average that accepts any number of numeric parameters, displays them, and displays their average. Test your function in your Main(). Tests will be run against Average() to determine that it works correctly when passed one, two, or three numbers, or an array of numbers.8- Create an instance of the following class and call its methods. class Exam{ int grade; public: void seta (int b) (grade=b; } int geta () {return grade; } 9- When the word const is put before the variable definition, what does that mean? 10- How to concatenate two strings in C++ language? C++1- Write a class that allows you to define complex numbers in C++ and call it complex. The class contains two private members named real and img. It also has a constructor to initialize its members to values other than zero. Then, write a four methods that implement the basic mathematical operations (+,-.*/) for two complex numbers. 2- The purpose of the method resize() in the IntegerArray class below is to dynamically change the size of the IntegerArray instance. This methid is implemented as follows: 1. create a new array with the desired size 2. copy the data form the old to new one 3. delete the old data 4. Make the old data pointer points to the newly created data 5. update the size field your task is to write the resize() method based on the above five steps. #include int main() { IntegerArray a(2); using namespace std; class IntegerArray { public: a.data[0] = 4; a.data[1] = 2; int *data; a.resize(5); int size; cout size = size; } -IntegerArray() { delete[] data; } void…
- Assignment 4 - Car Maintenance This assignment will assess your understanding of void and value returning static methods. Your cousin owns an automotive maintenance shop that performs routine maintenance on cars. He has asked you to write a program that will provide a list of services (and their respective prices) to users and allow them to choose any, or all, services they would like and display the final price, including a 28% labor charge, a 9% markup if the car is an import, and an 8% sales tax. Task To accomplish the above, do the following: • Write the two methods outlined below. • Test your program and screenshot your successful test. carMaintenance method This method should accept the make of the car as a parameter (e.g., BMW, Ford, Ferrari, etc.). It should display the services and their prices as follows: Services: Oil Change, Tune up, Brake Job, Transmission Service, respectively: 59.99, 111.99, 189.99, 149.99 These should be stored in parallel arrays.

- C++ Program: Random Number Guesser. Write a derived class of the NumberGuesser class named RandomNumberGuesser. The derived class should override the behavior of the getCurrentGuess method. It may also add member data and its own constructor. It may also override the higher(), lower() and reset() methods as you see fit. To get everyone started off on the same page I have written a NumberGuesser class. It is defined entirely in-line in the following file: NumberGuesser.h (Links to an external site.) https://fog.ccsf.edu/~mluttrel/cs110b/NumberGuesser.h In the current NumberGuesser class the getCurrentGuess() method returns the midpoint of the range of possible values. In your RandomNumberGuesser class the getCurrentGuess() method should return a randomly generated number in the range of possible values. Note that repeated calls to getCurrentGuess() should always return the same value for both classes if neither the higher() or the lower() functions are called. Consider the…public class Product { private String name; private double cost; public Product(String n, double c) { name=n; cost=c; } public String getName() { return name; On the left is code for a class called Product.

- TRUE OR FALSE A method that uses a generic class parameter can be static or dynamic.Q. Can I have a static method in a class that implements a data type?// The language is java Part I: Use of recursive method (4 points for students who need recursion/extracredit) Description: Code a class called RecursiveMultiply in which it will accept two integer arguments entered from user; pass these integers to a recursive method that returns the multiplication result of these two integers. The multiplication can be performed as repeated addition, for example, if two integers are 7 and 4: 8 * 4 = 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 You will write the application with GUI and recursion to display the result in a noneditable text field, based on the user’s entry from two text fields, while an OK button is pressed. You will utilize the exception handling code as you did in your Lab 4 and Lab 5 to verify if data entered in the text fields are valid (numerical and positive data only). You will make your own decision if there is any explanation that is not described in this specification. Finally, code a driver program that will test your class…
