70. A constructor operation does which of the following? a. Creates a new instance of a class b. Updates an existing instance of a class c. Deletes and existing instance of a class d. All of the above.

Classes and Objects) Hand-write a complete Java class that can be used to create a Car object as described below. a. A Vehicle has-a: i. Registration number ii. Owner name iii. Price iv. Year manufactured b. Add all instance variables C. The class must have getters and setters for all instance variables d. The class must have two constructors, a no-args and a constructor that receives input parameters for each instance variable.

5 (The Time class) Design a class named Time. The class contains: ■ Data fields hour, minute, and second that represent a time. ■ A no-arg constructor that creates a Time object for the current time. ■ A constructor that constructs a Time object with a specified elapse time since the middle of night, Jan 1, 1970, in seconds. ■ A constructor that constructs a Time object with the specified hour, minute, and second. ■ Three get functions for the data fields hour, minute, and second. ■ A function named setTime(int elapseTime) that sets a new time for the object using the elapsed time. Draw the UML diagram for the class. Implement the class. Write a test program that creates two Time objects, one using a no-arg constructor and the other using Time (555550), and display their hour, minute, and second. (Hint: The first two constructors will extract hour, minute, and second from the elapse time. For example, if the elapse time is 555550 seconds, the hour is 10, the minute is 19, and the…

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.

Summary In this lab, you create a derived class from a base class, and then use the derived class in a Python program. The program should create two Motorcycle objects, and then set the Motorcycle’s speed, accelerate the Motorcycle object, and check its sidecar status. Instructions Open the file named Motorcycle.py. Create the Motorcycle class by deriving it from the Vehicle class. Call the parent class __init()__ method inside the Motorcycle class's __init()__ method. In theMotorcycle class, create an attribute named sidecar. Write a public set method to set the value for sidecar. Write a public get method to retrieve the value of sidecar. Write a public accelerate method. This method overrides the accelerate method inherited from the Vehicle class. Change the message in the accelerate method so the following is displayed when the Motorcycle tries to accelerate beyond its maximum speed: "This motorcycle cannot go that fast". Open the file named MyMotorcycleClassProgram.py. In the…

Using classes, design an online address book to keep track of the names, addresses, phone numbers, and dates of birth of family members, close friends, and certain business associates. Your program should be able to handle a maximum of 500 entries. Define a class addressType that can store a street address, city, state, and ZIP code. Use the appropriate functions to print and store the address. Also, use constructors to automatically initialize the member variables. Define a class extPersonType using the class personType (as defined in Example 10-10, Chapter 10), the class dateType (as designed in this chapters Programming Exercise 2), and the class addressType. Add a member variable to this class to classify the person as a family member, friend, or business associate. Also, add a member variable to store the phone number. Add (or override) the functions to print and store the appropriate information. Use constructors to automatically initialize the member variables. Define the class addressBookType using the previously defined classes. An object of the type addressBookType should be able to process a maximum of 500 entries. The program should perform the following operations: Load the data into the address book from a disk. Sort the address book by last name. Search for a person by last name. Print the address, phone number, and date of birth (if it exists) of a given person. Print the names of the people whose birthdays are in a given month. Print the names of all the people between two last names. Depending on the users request, print the names of all family members, friends, or business associates.

Q3: Class called ( myclass) and an objects of this class called (obj1) and (obj2). This class contains two data members of type integer (a and b) with private access, and three member functions with public access: constructor to give valne to variables, and default constructor and show0 to display variables. Write a program to set and display the objects fields.

The operator that is required to access members of classes and structs is called: a. Colon operator b. Scope resolution operator c. Operator overloading d. Member access operator e. None of the answers Answer: What is the name of the program that uses and interacts with the class? Answer: By assuming that all libraries are included, replace MYFUNCTION with the proper function name to make the code correct: 001010 111101101 01010101111110 1010101010101 111010101010 0101100 vector> MyVector; int rows= 10, cols = 4; MyVector.MYFUNCTION(rows, vector(cols, 100)); cout << MyVector [0] [1] << endl; for (int i } = 0; i < MyVector.size(); i++) { for (int j 0; j < MyVector[i].size(); j++) cout << MyVector[i][j] << " "; cout << endl;

Please read the main function and define a class CStudent. (object array, static member, string) Please do not change the main function and complete the program given. 【Description】 Please read the main function and define  a class CStudent.  In the main funciton, two arrays of the ojbect of CStudent are define.  Please analyze the call of constructor and destructor in the process of creating and releasing objects. 1. CStudent has two private member variables：stirng name, int age.  2. CStudent has a static member count. It will be incremented by 1 when the object is created and decremented by 1 when the object is destroyed. 3. The constructor function should output "*** is contructing". The destructor function should output “*** is destructing”. "***" indicates the name of the current CStudent object.     【Input】 No input   【Output sample】 There are 0 students. noname is contructing noname is contructing noname is contructing noname is contructing noname is contructing name:noname…
