In Kotlin, Use this revised Employee class: data class Employee(val id: Int, val name: String, val wage: Double, val hours: Double) Create a list of Employees Write a function fireEmployee, which takes a list of Employees and an id number and returns a list that consists of all the original employees wihtout any that have that id. a) use filter in the function b) revise the function to take a function or a lambda to determine who gets fired. For example, you should be able to write a lambda and pass it to the function to result in everyone named "Xavier" getting fired. c) revise the function to use a tail-recursive helper function instead of filter

C++ program Hi i need help making the following function, ------>>>>>> friend bool operator<(Date& date1, Date& date2); the function is supposed to compare 2 date objects of the Date class ............................... It is supposed to overload the < operator to compare 2 Date objects. The comparison shall return true only if the Date object on the left represents a date earlier than the Date object on the right. The comparison shall not update either Date object. please help I provided all my code below: The following are the 3 libraries of my program --------------------------------------------------------------------------------------------------------------------------------------------------------- DATE.H file: #ifndef DATE_H#define DATE_H#include <string>using namespace std; class Date { private: string entered_date; int month_, day_, year_; public: Date(); Date(const string& entered_date); friend bool…

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…
Given main(), build a struct called BankAccount that manages checking and savings accounts. The struct has three data members: a customer name (string), the customer's savings account balance (double), and the customer's checking account balance (double). Assume customer name has a maximum length of 20.
c++ A FastCritter moves twice as fast as a regular critter. When asked to move by n steps, it actually moves by 2 * n steps. Implement a FastCritter class derived from Critter whose move function behaves as described. Complete the following file: fastcritter_Tester.cpp #include <iostream>using namespace std; #include "critter.h" /**A FastCritter moves twice as fast as a regular critter.*/class FastCritter:public Critter{public:void move(int steps);}; . . . int main(){FastCritter speedy;speedy.move(10);cout << speedy.get_history() << endl;cout << "Expected: [move to 20]" << endl;speedy.move(-1);cout << speedy.get_history() << endl;cout << "Expected: [move to 20, move to 18]" << endl;return 0;} Use the following file: critter.h #ifndef CRITTER_H #define CRITTER_H #include <string> #include <vector> using namespace std; /** A simulated critter. */ class Critter { public: /** Constructs a critter at position 0 with blank…

In C++ Please: THE PROGRAM CANNOT CONTAIN -> OPERATORS! Create a class AccessPoint with the following: 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. 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 do. 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. Represent this with bars like, IIIII. Each bar can represent 20% Test your class by writing a…
for c++ Write a program that allows two players to play the tick-tac-toe game. Your program must contain the class ticTacToe to implement a ticTacToe object. Include a 3-by-3 two-dimensional array, as a private member variable, to create the board. If needed, include additional member variables. Some of the operations on a ticTacToe object are printing the current board, getting a move, checking if a move is valid, and determining the winner after each move. Add additional operations as needed.
