Define a default constructor that initializes the data members, integer áreaCode, integer number, and string greeting, with the default values 1,-1, and "Undefined", respectively. Ex: If the input is 597 6215586 Guy, then the output is: Area code: 1, Number: -1, Greeting: Undefined is not available now Area code: 597, Number: 6215586, Greeting: Guy is not available now Note: The class's print function is called first after the default constructor, then again after the inputs are passed to the setters. 5 class Voicemail { 6 7 Voicemail(); 8 void SetAreaCode (int voicemailAreaCode); 9 void SetNumber(int voicemailNumber); 10 void SetGreeting (string voicemailGreeting); void Print();. 11 12 13 14 15 16 public: private: int areaCode; int number; string greeting; 17); 18 19 Your rede es her / Scann 21 void Voicemail:: SetAreaCode (int voicemailAreaCode) { 22 areaCode = voicemailAreaCode;

Write program in C++ Language The other solutions on chegg were incorrect! Please read carefully! Write a program that defines and tests a class called COP3014. The class resembles aclassroom. It has the following grading scheme:3 quizzes 20 points each 20%Mid term 100 points 30%Final 100 points 50%Based on the total grade of any student for the course, the letter grade of each student can becomputed as follows:Any grade of 90 or more is an A, any grade of 80 or more (but less than 90) is a B, any grade of70 or more (but less than 80) is a C, any grade of 60 or more (but less than 70) is a D, and anygrade below 60 is an F.This class needs to have some member variables. The first name, last name, the Z-number, thegrades, the total grade and final letter grade are all considered to be private member variablesof this class.The class should also have the following public member functions/procedural attributes that canbring the objects (students of the class) to life and give them some…
Using C++ define the class called Student. The Student class has the following: Private data members: name(string), age(int), units(int). The units represent the number of quarter units student is enrolled in. Define a default constructor as well as a constructor with parameters for the class Student. The class must have get and set functions for all private data members. The set function for the data member units must throw “out_of_range” exception if the number of units is not between 1 and 15. Include a function called tuition (double feePerUnit) that computes and returns the cost of registering for the number of units (in the private data member). The function receives the cost per unit as a parameter. Overload the operator (<<) to display student name and age. Test the class Student by writing a main program in which a Student object is created and displayed. Call the function tution(), you may pass any value as feePerUnit parameter to this function and display the…
Rewrite the calculator program using a class called calculator. Your program will keep asking the user if they want to perform more calculations or quit and will have a function displayMenu to display the different functions e.g .(1 - addition, 2- subtraction, 3- multiplication, 4- division) Your program must have appropriate constructors and member functions to initialize, access, and manipulate the data members as well as : A member function to perform the addition and return the result A member function to perform the subtraction and return the result A member function to perform the multiplication and return the result A member function to perform the division and return the result
Write C++ code for a class named MuniBus that has the following private member variables: int totalPassengers; double faresCollected; and the following public member functions: void passengerBoard() - adds 2.50 to faresCollected and adds 1 to totalPassengers double getFaresCollected() - returns faresCollected int getPassengers() - returns totalPassengers void reset() - sets totalPassengers and faresCollected to zero MuniBus() - default constructor. Initializes both totalPassengers and faresCollected to 0 MuniBus(int tp, double fc) - constructor which initializes totalPassengers to tp, faresCollected to fc ~MuniBus() - destructor. Prints out a message saying that the bus is being destroyed, and also prints out totalPassengers and faresCollected. Write the class declaration and implement all of the constructors, the destructor, and member functions. You do not need to demonstrate using your class or show output.
Write a program in C++ to help a teacher to automate her grading system. Your program will have the following: 1 - A struct named studentInfo with the following members: • firstName, variable of type string • lastName, variable of type string • ID, variable of type string 2 - A struct named courseGrade with the following members: • total, variable of type int • Final, variable of type int • sum, variable of type int 3- A struct named student with the following members: • info, variable of type studentInfo • grade, variable of type courseGrade • status, variable of type bool 4 - A function inputData to prompt the user to enter the information of the student. The function accepts one parameter of type student. 5 - A function computeSum to compute and set the total of all grades (total+final). The function accepts one parameter of type courseGrade. 6 - A function setStatus to set the status of the course. If the sum>=50 then, the student passed the course else,…

IN C++ Lab #6: Shapes Create a class named Point. private attributes x and y of integer type. Create a class named Shape. private attributes: Point points[6] int howManyPoints; Create a Main Menu: Add a Triangle shape Add a Rectangle shape Add a Pentagon shape Add a Hexagon shape Exit All class functions should be well defined in the scope of this lab. Use operator overloading for the array in Shape class. Once you ask the points of any shape it will display in the terminal the points added.
Define a default constructor that initializes the data members, string title and integer year, with the default values "Empty" and -1, respectively. Ex: If the input is Magnolia 1989, then the output is: Title: Empty, Year: -1 Title: Magnolia, Year: 1989 Note: The class's print function is called first after the default constructor, then again after the inputs are passed to the setters. 5 class Book { 6 public: 7 8 9 10 11 12 13 14 15 }; 16 Book(); void SetTitle(string bookTitle); void Set Year (int bookYear); void Print (); private: string title; int year; 17 Your code goes here */ 18 19 void Book::SetTitle(string hook Title) { CS Scarint (19 bi Title mscanner 22 23 void Book Set Year(int bookYear) [ 2
In C++ Please: THE PROGRAM CANNOT CONTAIN -> OPERATORS! Create a class AccessPoint with the following: x - a double representing the x coordinate y - a double representing the y coordinate range - an integer representing the coverage radius status - On or Off Add constructors. The default constructor should create an access point object at position (0.0, 0.0), coverage radius 0, and Off. Add accessor and mutator functions: getX, getY, getRange, getStatus, setX, setY, setRange and setStatus. Add a set function that sets the location coordinates and the range. Add the following member functions: move and coverageArea. Add a function overLap that checks if two access points overlap their coverage and returns true if they do. Add a function signalStrength that returns the wireless signal strength as a percentage. The signal strength decreases as one moves away from the access point location. Represent this with bars like, IIIII. Each bar can represent 20% Test your class by writing a…
