In C++ Please: The class and functions need to be on an .h file while the main needs to be small and on a seperate .cpp file. Create a class AccessPoint with the following attributes: 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. Also, 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 overlap. 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. Test…
This part of the quiz will contain 4 parts. A function called grade, a function called pgrade, a prototype file called grade.h and a main function. In this part you will create the main function which will do the following: main This main function will use the functions grade and pgrade to produce the grades for the following students and display the appropriate grade with the appropriate message. The semester grade will be based on the fact that the quiz average is 25% of the grade, the final is 20% of the grade, assignments is 20% of the grade and programs are 35% of the grade. The student grades are as follows: Student Name Assignments Programs Quiz Ave Final Tom 63 Francis Maria Jan 75 90 95 85 sample of output Harry Grade B Good 85 75 95 90 93 92 71 69 87 91 73 A
def sw_vehicle_search(cargo_capacity: int, max_speed: int, cost: int) -> list: This function will use the https://swapi.dev/ API to collect its information. This function is meant to be used to search for vehicles in Star Wars that meet the specified criteria. The function should return a list of names of the vehicles that have cargo capacities and a max speed greater than or equal to the value specified but also cost less than or equal to the cost given. Vehicles with "unknown" or "none" for any of the mentioned categories should not be regarded.  Keep in mind that not all of the vehicles in star wars are returned in one request to https://swapi.dev/api/vehicles/. The JSON object returned by this request has a next attribute that represents the next page of information. You must make multiple requests for each page to collect all vehicle information. You might find it helpful to use the following API handle(s): https://swapi.dev/api/vehicles/ - to retrieve all vehicles in Star Wars…
(1) Create three files: ItemToPurchase.h - Class declaration ItemToPurchase.cpp - Class definition main.cpp - main() function Build the ItemToPurchase class with the following specifications: Default constructor Public class functions (mutators & accessors) SetName() & GetName() SetPrice() & GetPrice() SetQuantity() & GetQuantity() Private data members string itemName - Initialized in default constructor to "none" int itemPrice - Initialized in default constructor to 0 int itemQuantity - Initialized in default constructor to 0 (2) In main(), prompt the user for two items and create two objects of the ItemToPurchase class. Before prompting for the second item, call cin.ignore() to allow the user to input a new string.Ex: Item 1 Enter the item name: Chocolate Chips Enter the item price: 3 Enter the item quantity: 1 Item 2 Enter the item name: Bottled Water Enter the item price: 1 Enter the item quantity: 10 (3) Add the costs of the two items together and output the…
