Explanation of Solution
Function declaration:
// Declaration of subtract() function
friend Money subtract(Money amount1, Money amount2);
The above function declaration is the “subtract()” friend function.
- In the class “Money”, add the declaration part in the “public” section below the “equal()” function declaration.
Function definition:
// Definition of substract() function
Money subtract(Money amount1, Money amount2)
{
// Create an object for Money class
Money temp;
// Compute amount and assign to temp...

Create a class called Name that contains data members of type string called first name, middle
name, last name, and salutation. Add a constructor that takes four parameters which are used to
initialize the four data members and a member function called to-string that returns the person's full
name in the form of “Salutation First name Middle name Last name”. Finally add set and get functions
for all the data members. Add a destructor to the program displaying a suitable msg.
Write a program that contains variables to hold employee data like; employee Code, employee Name and date Of Joining. Write a function that assigns the user defined values to these variables. Write another function that asks the user to enter current date and then checks if the employee tenure is more than three years or not. Call the functions in main.Now write a runner class that declares two employee objects and check their tenure periods.
Novice: How can i access a main class objects from outside the function? / Better Alternative?
If i have 4 Student objects how can i print the information for the specific object given one parameter about the class, like the students Idnumber.
What i came up with was making a checkId void function that takes the user input and runs an if else chain checking if the Id belongs to student 1-4 then printing the details of that classes object with the void function print. ideally i would want the if-else chain in the checkId function to call the print( student1-4) class object but im not sure how to properly do that.
i dont think this is the best way to go about it, if you have any recommendations or alternatives please help me out.

- Create a class Employee with following data members, name, id, and salary as private datamember. Create array of objects for four employees, compare their salary using operatoroverloading, and display the records of the student who is getting less salary. by c++arrow_forwardWrite a C++ class to represent an Employee. Each employee is given a name, an age, a NIC number, anaddress, and a salary. Furthermore: The Employee class should keep track of how many employees (objects) have been created inthe system. Your Employee class should initialize all of its fields via a constructor. Create function prototypes to set and get an employee's zip code. Declare a print_employee() function that prints all of an employee object's details.(Whenever possible, use constant functions.)arrow_forwardWrite in python. Write a class named Employee that has **private** data members for an employee's name, ID_number, salary, and email_address. It should have an init method that takes four values and uses them to initialize the data members. It should have get methods named get_name, get_ID_number, get_salary, and get_email_address.Write a separate function (not part of the Employee class) named **make_employee_dict** that takes as parameters a list of names, a list of ID numbers, a list of salaries and a list of email addresses (which are all the same length). The function should take the first value of each list and use them to create an Employee object. It should do the same with the second value of each list, etc. to the end of the lists. As it creates these objects, it should add them to a dictionary, where the key is the ID number and the value for that key is the whole Employee object. The function should return the resulting dictionary.For example, it could be used like…arrow_forward
- Write a program which have a class named as “Student”, while the data members of the class are, a. char name[10], b. int age; c. string color; d. string gender; e. double cgpa; and the member function “print()”, is just to display these information. 1. You need to create 3 objects of the “Student” class. 2. Initialize one object by the default constructor having some static values. 3. Initialize the second object by the parameterized constructor, while you need to pass values for initialization. 4. Initialize the third object by copy constructor. 5. Display the values of all the objects by using the “print()” method. 6. At the end destroy the objects via destructor. 2. Write a C++ program that creates a class called laptop. The data members of the class are Ø brand (string) Ø serial (int) Ø color (string) Ø price (float) Ø processor_speed (double) 1. The constructor should accept the laptop brand, model, serial, color, price, processor speed, ram…arrow_forwardIn C++ Create a class called Pencil. Pencil has a type. Create another class called Customer. The customer class should have a ID number, array (using pointers) called purchases, and a Pencil variable. Make sure to create the purchases array in the constructor. Create a function to fill in purchase amount. Create a way to output all the information about a customer, including all the details about their type of pencil.arrow_forwardI am trying to create a class called Car in Python with yearModel, make, and speed as attributes. I want to create a two-element constructor that accepts values to set yearModel and make. I need getter/setter functions for each attribute. An accelerate function to increment speed by 5 and a brake function to decrement by 5. I also want a main driver function to accept user input for a year and make of the car. I want to repeatedly call the accelerate and brake functions. I need to output the incrementing speed and decrementing braking speeds. As well as the cars year and make and starting 0 speed. This is the code I have so far, I mainly need help figuring out how to ask for user input at the end. class Car: def __init__(self, yearModel, make, speed): self.yearModel = yearModel self.make = make self.speed = 0 def getyearModel(self): return(self.yearModel) def getmake(self): return(self.make) def getspeed(self):…arrow_forward
- IN C++ In your previous class, move the member variables (student name and grades) as private. Create the proper functions to fill data in them. In main, create an instance of that array and fill that instance with data. Call the DisplayInfo() function from main so it prints the content of the object.

Write a class definition for a class named Fraction that contains two integer fields named numerator and denominator. Include in the class a prototype for a method (function) named add that takes two Fraction objects as input arguments and returns a Fraction object as output. You do not need to provide an implementation of the add method.arrow_forward1. Short questions: a. What is the difference between having a function return type being "const dataType &" and it being "dataType&"? b. When is it necessary to make a function or a class a friend of another class? c.

- Write a class called rectangle. Your task is to store the length and width of the rectangle. Write a member function called increment that will add 1 to the value of length and width. Also write a funnynction that will compute the area of the rectangle. Finally write an accessor function that will display the length, width and area of the rectangle. Demonstrate the use of the object in the main function. Make sure that the function names are meaningful and self-descriptive. class rectangle { Private: Int length, width, area; Public: }arrow_forwardUsing Cpp/C++ Create an Account class that a bank might use to represent customers’ bankaccounts. Include a data member of type int to represent the account balance. [Note: In subsequentchapters, we’ll use numbers that contain decimal points (e.g., 2.75)—called floating-point values—to represent dollar amounts.] Provide a constructor that receives an initial balance and uses it to initializethe data member. The constructor should validate the initial balance to ensure that it’s greaterthan or equal to 0. If not, set the balance to 0 and display an error message indicating that the initialbalance was invalid. Provide three member functions. Member function credit should add anamount to the current balance. Member function debit should withdraw money from the Accountand ensure that the debit amount does not exceed the Account’s balance. If it does, the balanceshould be left unchanged and the function should print a message indicating "Debit amount exceededaccount balance."
