For this lab task, you will work with classes and objects. Create a class named text that works similar to the built-in string class. You will need to define a constructor that can be used to initialize objects of this new class with some literal text. Next, define three methods: to_upper() that will convert all characters to uppercase, reverse() that will reverse the text and length() that will return the length of the text. After you have completed this part, copy the following mainfunction to your code and check if the implementation is correct. int main() { text sample = "This is a sample text"; cout << sample.to_upper(); // This should display "THIS IS A SAMPLE TEXT" cout << endl;cout << sample.reverse(); // This should display "txet elpmas a si sihT"cout << endl; cout << sample.length(); // This should display 21 }
Write a class CountObject which has a method namenumberfoObjects() which returns the number of objects been created ofthat class. Also write a class that will create few objects of CountObjectclass and show the count. (Hint: you have to use static variable inCountObject class).
Create a Python class, Document. Using PYTHON: The instances of this class have the following attributes: word_count, status, grade, asked_grade_before_submission_count and the following methods: add_words, submit, get_grade,_str_. For this exercise, we will add the following attribute/s: (1) key - a class attribute that determines the output when printing the document instance. It has a value of 0 by default. Let us also add these additional method/s for the Document class: (1) copy_content - takes in source_document as a parameter of type Document then updates the word_count of the destination document (or the document where this method was invoked). The word_count is updated accordingly so that the content of the destination document is replaced by the source document. (2) append_content - takes in source_document as a parameter of type Document then updates the word_count of the destination document. The word_count is updated such that the content of the source document is appended…
Why is it important for a class to have a destructor implemented? With your comment, fill in the spaces.
create two data members on each of the four classes we created (MyPoint, Mysegment, MyShape, and xyGroup). You also need a boolean, to declare it picked, and a color to paint it. also create a method called select (or pick). So we add the two new members, color and isselected:
Help, I making a elevator simulator, I need help in writing code in the Elevator class and it's polymorphism class. I am not sure what to do next. Any help is appreciated. There are 4 types of passengers in the system:Standard: This is the most common type of passenger and has a request percentage of 70%. Standard passengers have no special requirements.VIP: This type of passenger has a request percentage of 10%. VIP passengers are given priority and are more likely to be picked up by express elevators.Freight: This type of passenger has a request percentage of 15%. Freight passengers have large items that need to be transported and are more likely to be picked up by freight elevators.Glass: This type of passenger has a request percentage of 5%. Glass passengers have fragile items that need to be transported and are more likely to be picked up by glass elevators. There are 4 types of elevators in the system:StandardElevator: This is the most common type of elevator and has a request…
Lab 6 - Exercise 2. Write a test driver that reads data about two surgeons and print the specialization of the doctor with the highest salary using the method that compares the salary of surgeons. A Doctor class has the following private data members, constructor, and public methods: name (String) salary (int) End of document I A constructor without parameters, A constructor with parameters, A set method for the data variables (one method) A get method for each data members. A method to print Doctor information A Surgeon is a subclass of Doctor with the following private data members, constructor, and public methods: specialization (String) degree (string) A constructor without parameters, A constructor with parameters, · A set method for the data variables (one method) · A get method for each data member. · A method to print all Surgeon information. · A method that compares the salary of two Surgeons and return the specialization of the doctor with the higher salary. 1. Implement the…
Which of the following, can be done, with the help of the this reference?
Consider the code of both classes A.cpp and B.cpp listed below. Read carefully the code of class A and Class B. 1- Replace ? with public. Would the code of class B compile? Explain why or why not the code of B will or will not compile (10 points). Provide me with the output as a comment at the end of the code. Submit both codes as LastName_FirstName_A.cpp and LastNameFirstName_B.cpp. 2- If we replace ? in class A with protected, would the code of class B compile? Explain why or why not the code of B will or will not compile (10 points). Comment out the line in code B that is causing the error. Compile and verify that the code works. Provide me with the output of B.Submit both codes as:LastName_FirstName_A_Proctected.cpp LastNameFirstName_B_Proctected.cpp. 3- If we replace ? in class A with private, would the code of class B compile? Explain why or why not the code of B will or will not compile (10 points). Submit both codes as: LastName_FirstName_A_Private.cpp…
2 part question I am using eclipse! Create a class Circle, which - has a field radius (double) It should have appropriate accessor and mutator. If the Circle instance is created without parameter, the radius should be set to 1.0. Otherwise the radius should be set to the specified value. The Circle class should have a class level (not instance level) field called Pi. Since Pi is a known constant (3.14159), this field should be a constant. This variable can be accessed directly by outside objects. This Circle class should have a getArea() method and getPerimeter() method. You need to decide their return value and access level. Note: Area = Pi * radius * radius Perimeter = 2 * Pi * Radius part 2 Create a subclass of Circle class ColoredCircle by implementing the ColoredShape interface. It should have a field color of type enum ShapeColor. ColoredShape.java ShapeColor.java ColoredCircle should have two constructors. One will takes one parameters radius and set the color to…
Fill in the missing code for the following "intercept" method, located within an "InterceptTokenService” class. This method must add an “Authorization” header to the request with the value: "JWT token”, where token is the current, saved token. NOTE: You may assume that an AuthService (injected into the class as "auth") provides a means of fetching the correct token using a "getToken()" method. intercept(request: HttpRequest , next: HttpHandler): Observable { // … your code here }
Assume that all source files are in the same package. Note that some lines may wrap, but are still considered on one line. Examine the code below. Recall that variables have four kinds of scope: static, instance, local, and block. For each variable listed below, identify its scope (static, instance, local, or block) and describe the scope using complete sentences. An example description is provided, after the code listing, for the ounces variable in the Beverage2 class. Please describe the scope for the following variables: The num variable in the Beverage2 class The price variable in the Beverage2 class The shots variable in the Espresso class The b variable in the TestBeverage2 class The j variable in the TestBeverage2 class public abstract class Beverage2 { private static int num; private int ounces; private double price; protected Beverage2(int ounces, double price) { this.ounces = ounces; this.price = price;…
