- hi i need solution for this Each account should have a constant, unique id. Id numbers should start from 1000 and increment by 5. The ACCOUNT_ID attribute should be initialised when the account object is created. The id should be generated internally within the class, it should not be passed in as an argumentTask 2: Create a class that includes a data member that holds a “serial number” for each object created from the class. That is, the first object created will be numbered 1, the second 2, and so on. To do this, you’ll need another data member that records a count of how many objects have been created so far. (This member should apply to the class as a whole; not to individual objects. What keyword specifies this?) Then, as each object is created, its constructor can examine this count member variable to determine the appropriate serial number for the new object. Add a member function that permits an object to report its own serial number. Then write a main() program that creates three objects and queries each one about its serial number. They should respond I am object number 2, and so on. Paste only class definition here Paste function definitions of member functions one by one in different rows Member function 1() here Member function 2() here…True or False: Object privileges allow you to add and drop users
- Which of the following statements are true? options: Every class has a copy constructor with the signature ClassName(const ClassName&). The copy constructor can be used to create an object initialized with another object's data. By default, the copy constructor simply copies each data field in one object to its counterpart in the other object. By default, the copy constructor performs a shallow copy.1. Which design pattern lets you define a new operation without changing the classes of the elements on which it operates? A) Visitor B) Command C) Decorator D) Chain of Responsibility 2. Which design pattern decouples the object that invokes the operation from the one that knows how to perform it? A) Command B) Strategy C) Visitor D) State 3. Which pattern to use when more than one object can handle a request and the handler is unknown? A) Chain of Responsibility B) State C) Visitor D) Command 4. The Tic-Tack-Toe is a classical Artificial Intelligence problem for which many algorithms have been proposed to solve it over the years. You were asked to provide a software component where the user can choose one algorithm at a time and try it. Which design pattern you will use? A) Strategy B) Visitor C) Chain of Responsibility D) CommandWhich of the following statements is correct about an accessor member function? Group of answer choices It cannot be declared with the keyword const. It returns the value of a data member of an object but does not modify any data member values. It modifies one or more data members of an object. It is only called by other member functions of an object.
- Implement and test each feature. The application should have the following basic features: Note: The program should validate user input accordingly. All attributes should be private for data encapsulation 1. A non-member can register to become a member (information is recorded). 2. A non-member can view all house details (but not their reviews and availability). 3. A member can login with the registered username and password, and can view all of his/her information.
