Next, write a class named Customer that is a subclass of the Person class. The Customer class should have a data attribute for a customer number, and a Boolean data attribute indicating whether the customer wishes to be on a mailing list. Demonstrate an instance of the Customer class in a simple program.Write a code for a banking program.a) In this question, first, you need to create a Customer class, this class should have:• 2 private attributes: name (String) and balance (double)• Parametrized constructor to initialize the attributes• Methods:i. public String toString() that gives back the name and balanceii. public void addPercentage; this method will take a percentage value andadd it to the balanceb) Second, you will create a driver class and ask the user to enter 6 customers’ informationand then you will create an array of Customer objects.c) Then you use this array used for various operations as shown in the output.• Using the array of customer objects, you need to search for all customers whohave less than $150• Using the array of customer objects, you need to get the average balance of thebalances in this array• Using the array of customer objects, you need to get the customer with thehighest balance and lowest balance• Using the array of customer objects, you need to show all…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?

Write appropriate accessor and mutator methods. Also, write a program that creates three instances of the class. One instance should hold your information, and the other two should hold your friends’ or family members’ information.

When ever engine starts it should reset the attribute TTK (Total travel kilometer) to zero and attribute Fuel to 100. On fly() it should add 10 kilometers if the Fuel attribute is greater than zero and decrement Fuel by 20.On land() it should print total distance covered. Write the code providing all necessary details. And then show working object of Plane in main().python language Write a function that overwrite the greater than method for a class. The class has a field variable called score. The lower the score, the better. INPUT: Nothing? NOTE: this method is inside the class OUTPUT: Nothing is output RETURNED: The boolean result of the new comparison
- Computer Science write a c# program code 1) Write a class with the following features: a. Two instance variables, type string and string[] b.

C++Nutritional information (classes/constructors) PYTHON ONLY Complete the FoodItem class by adding a constructor to initialize a food item. The constructor should initialize the name (a string) to "None" and all other instance attributes to 0.0 by default. If the constructor is called with a food name, grams of fat, grams of carbohydrates, and grams of protein, the constructor should assign each instance attribute with the appropriate parameter value. The given program accepts as input a food item name, fat, carbs, and protein and the number of servings. The program creates a food item using the constructor parameters' default values and a food item using the input values. The program outputs the nutritional information and calories per serving for both food items. Ex: If the input is: M&M's10.034.02.01.0 where M&M's is the food name, 10.0 is the grams of fat, 34.0 is the grams of carbohydrates, 2.0 is the grams of protein, and 1.0 is the number of servings, the output is:…Consider the following code segment and answer questions 14 and 15. class Point { public: Point (double x = -99, double y = -99) { this -> xM = x; this -> yM = y;} double getx () {return xM; } double gety () {return yM; } void setx (double x) {this -> xM = x; } void sety (double y) {this -> yM = y; } private: double xM, yM; }; 14. What is the output of the following code snippet: Point pl (100); cout << pl.getx() << " " << pl.gety(); a. The output of the program is: -99 -99 b. The output of the program is: 100 100 c. The output of the program is: -99 100 d. The output of the program is: 100 -99 e. None of the above. It doesn't compile because constructor of Point needs two arguments. 15. How many times does the constructor of class Point get called by the following code snippet: Point a (100, 200); Point b[6]; Point *c = new Point; Point *d = new Point (300, 400); a. Four times b. Three times c. Nine times d. Two times e. None of the above
