This is in c++ The base class Pet has private data members petName, and petAge. The derived class Dog extends the Pet class and includes a private data member for dogBreed. Complete main() to: create a generic pet and print information using PrintInfo(). create a Dog pet, use PrintInfo() to print information, and add a statement to print the dog's breed using the GetBreed() function. main.cpp #include <iostream> #include<string> #include "Dog.h" using namespace std; int main() { string petName, dogName, dogBreed; int petAge, dogAge; Pet myPet; Dog myDog; getline(cin, petName); cin >> petAge; cin.ignore(); getline(cin, dogName); cin >> dogAge; cin.ignore(); getline(cin, dogBreed); // TODO: Create generic pet (using petName, petAge) and then call PrintInfo // TODO: Create dog pet (using dogName, dogAge, dogBreed) and then call PrintInfo // TODO: Use GetBreed(), to output the breed of the dog } Dog.cpp #include "Dog.h" #include…
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…

A binary operator is an operation that is performed on two operands. For example, addition is a binary operator that adds two operands (e.g., 2 + 4). In the provided UML diagram, all binary operators have two operands and an execute method that performs the appropriate operation on the operands. The AddOperation class should add the two operands. The SubtractOperation class should subtract the two operands. Here is an example of how a binary operator could be used: IBinaryOperator operator = new AddOperator(8, 12);System.out.println(operator.execute()); // should print 20operator.setLeftOperand(18);System.out.println(operation.execute()); // should print 30 crate a Main.java to test your code
Following programs contain syntax/logical errors. Underline the error and explain precisely the cause of the error to get any credit. Just underlining will not be given credit.
