- In this task, we’re going to be simulating an email message. Some of the logic hasbeen filled out for you in the email.py file.● Open the file called email.py.● Create a class definition for an Email which has four variables:has_been_read, email_contents, is_spam and from_address.● The constructor should initialise the sender’s email address.● The constructor should also initialise has_been_read and is_spam to false.● Create a function in this class called mark_as_read which should changehas_been_read to true.● Create a function in this class called mark_as_spam which should changeis_spam to true.● Create a list called inbox to store all emails (note that you can have a list ofobjects).● Then create the following methods:○ add_email - which takes in the contents and email address from thereceived email to make a new Email object.○ get_count - returns the number of messages in the store.○ get_email - returns the contents of an email in the list. For this, allowthe user to input an index…Which of the following applies to destructors? Choose all that apply. A.) A destructor is a function that automatically gets called when an object of its class falls out of scope. B.) If you create a copy constructor, you must also create a copy destructor. C.) A destructor cannot take any parameters. D.) A destructor cannot return a value.Create a class MyTime which has the datamembers as follows: 1. hour: integer (1 to 12)2. minute: integer (0 to 59)3. second: integer (0 to 59)4. pm: bool variable. True means PM time and false means AM time. Implement a default constructor, a parameterized constructor and a copy constructor. Write set and get functions for all the four members of the class. Overload these operators: 1. Extraction operator >> : Prompt the user for hours, minutes, seconds and for am/pm and initialize the structure. Left operand istream object and right operand MyTime2. Assignment = : Assign the right object to the left object. Both operands are of type MyTime.3. Insertion << : Print the time in the format HH:MM SS PM. Left operand of type ostream and right operand of type MyTime. this in c++.
- Given the FirstNames Array of 5 elements Bill Jack Jim Joan Fred What would FirstNames(5) return assuming that the array starts with element 1? A function is similar to a procedure or sub-module but a function can do this _________ while a procedure or sub-module cannot. In a text file, this is written to the file after each item? Inheritance allows The creation a new class from the members of an existing class The creation of a blank new class The destruction of an old class The modification of data in a class A variable that is being access from an area of the program that the can access the variable is calledImagine a publishing company that markets both book and audiocassette versions of its works. Create a class publication that stores the title (a string) andprice (type float) of a publication. Create a default constructor and also create parameterized constructor. Also derive two other classes:book, which adds a page count(type int), and tape, which adds aplaying time in minutes (type float). Write appropriate accessor’s and mutator’s and also member functions for each class. Store all information into a file named “BookData.txt”. Read all Data from file and display it on the screen with the help of their member function. Write a main() programto test the book andtape classes by creating instances of them, asking the user to fill in data with their appropriate accessors and mutators.Identify all the classes implement inheritance between them.(Note: write data using append mode otherwise previous information will be lost).With the coding below ,Complete the part labelled ‘//2 a) i’, write the constructor function that outputs “~~Building Created~~” and labelled //2 a) ii’, write the codes to define function findLargest(…). This function will receive an array of 5 Room objects and display the area width x length) of each object. The largest room area will be determined and displayed accordingly. #include <iostream> using namespace std; class Room { int width, length; public: // 2 a)to complete void setData (int L, int T) { width = L; length = T; } friend class Building; } ; class Building { string name; public: Building() { name = "Building"; cout<<"----Buiding name : "<<name<<"-------"<<endl; } // 2 a)to complete }; int main() { Building B1; Room r[5]; int i = 0, x, y; while( i < 5 ) { cout<<"Enter the tables' width and length :\n"; cin>>x>>y; r[i]. setData(x,y); i++; } B1.findLargest(r); return 0; }
- 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.Implement the Rectangle class as discussed this week. Use the class declaration below. Your job is to implement the functions. Implement the missing functions yourself. class Rectangle{ private: double width; double length; char *name; void initName(char *); public://constructorsRectangle();Rectangle(double, double, char*);//destructor ~Rectangle(); void setWidth(double); void setLength(double); void setWidth(char *); void setLength(char *); void setName(char *); double getWidth() const; double getLength() const; void printName() const { cout << name; }}; A few notes on the functions: initName(char *): this is a private member function. It should be the only function which dynamically allocates a char array to hold the name. setName(char *): this is a public member function which changes the name of the rectangle to a new name. It does not dynamically allocate memory, it only changes name. Demonstrate your class works…Create functions to test the validity of month, day, year, and store these in a separate file called modVerifyDate:isValidMonth isValidDay isValidYear HINT: for testing the day, this method of the CALENDAR module will be useful: monthrange(year, month) Returns weekday of first day of the month and number of days in month, for the specified year and month. Create an employee class The requirements for the class are as follows: Must have at least 4 private attributes/characteristics – one must be an object of type date Must have getter methods for each of the attributes Must have setter methods for each of the attributes Must have an str method to print the object with appropriate labels for each attribute Must have a constructor ( __init__) Must have a method which calculates using date objects If your class is about employees, calculate the number of years worked given the startDate. Store this in a SEPARATE file called…
