Design a new Account class as follows:■■ Add a new data field name of the String type to store the name of thecustomer.■■ Add a new constructor that constructs an account with the specified name, id,and balance.■■ Add a new data field named transactions whose type is ArrayList thatstores the transaction for the accounts. Each transaction is an instance of theTransaction class, which is defined as shown in Figure ■■ Modify the withdraw and deposit methods to add a transaction to thetransactions array list. Write a test program that creates an Account with annual interest rate 1.5%,balance 1000, id 1122, and name George. Deposit $30, $40, and $50 to theaccount and withdraw $5, $4, and $2 from the account. Print an account summarythat shows the account holder name, interest rate, balance, and all transactions.

Create a class POINT to represent a point in Cartesian coordinate system Chooseappropriate data members. Provide member functions: Default constructor Parameterized constructor Input  Output Distance( returns the distance between two POINT objects, the function takes one objectas an input) isZero(determines if a point is the center) Midlepoint(returns the middle point , takes one object as an input and returns the answerin a POINT object) isEqualTo (compare two POINTs) isGreaterThan (compares two POINT in terms of the distance from the center )o Above two function takes one POINT object as an argument and returns true ifthe condition is satisfied and false otherwise. plz solve it with C++.
Problem 2: Route Planning You are on the development team for a Route Planning application. The team has already developed a class named NavigatorApp for storing and displaying the graph representing the road network. This class has a void displayShortestPath() function which takes the source and destination vertices of the trip and displays the shortest route between them. Using the strategy pattern, draw a class diagram of the system which will allow for the NavigatorApp to display the shortest driving, walking, or cycling route when the displayShortestPath() function is called. You can assume that another developer is in charge of making sure the appropriate strategy is correctly set and for calling the displayShortestPath() function Starter code /* Modify NavigatorApp (if necessary) */ class NavigatorApp { private: Graph map; public: void displayMap(Window * window); void displayShortestPath(Vertex source, Vertex destination, Window * window); /* write pseudo code for this function…
Written in Python It should have an init method that takes two values and uses them to initialize the data members. It should have a get_age method. Docstrings for modules, functions, classes, and methods
The issue is that the tasks asks for the member_id no_of_books_bought amount_spent all to be returned. it also askes them to go by different names as in isMemberID, getBooksPurchase, getTotalAmountSpent, purchaseBook. It also has to has to reset the corresponding member variables to 0

Question 1 Write a Python class named Histogram that keeps track of how many times each unique element in a given sequence occurs. This class will implement the following interface: • Histogram( sequence ) will create a histogram of all elements occurring in the given sequence. This class cannot use the dict or collections.Counter types to create instance or class variables in order to implement the following specifications! If it does, the grade for your solution will automatically be zero! However, in some cases, your code will have to return dictionaries. So note the difference between the two specifications! • get( element-None, default-e ) will return how many times given element occurs in the histogram. If no element is specified, then the get () function will retum a dictionary where keys are elements and values are number of times a given element occurs in the sequence provided to the initializer. For example, given h - Histogram( "aaabbc" ) then h.get( "b" ) should return 2,…
