Name the different types of constructors that a designer can provide in a class. Provide an example with a class showing many co

Marrrta [24]

By default, if you do not implement a constructor, the compiler will use an empty constructor (no parameters and no code). The following code will create an instance of the MyObject class using the default constructor. The object will have the default vauesfor all the attributes since no parameters were given.

MyObject obj = new MyObject();

Another type of constructor is one with no parameters (no-arg constructor). It is similar to the default, except you actually create this constructor. The contents of the the constructor may include anything. To call a no-arg constructor, use the same line of code as above. The constructor can look like the one below:

public MyObject() {
System.out.println("This is a no-arg constructor");
}

Lastly there is the parameterized constructor. This type of constructor takes in parameters as inputs to assign to values in the newly created object. You call a parameterized constructor as follows:

MyObject obj = new MyObject("Bob", 20);

The constructor will look like this:

public MyObject(String name, int age) {
this.name = name;
this.age = age;
}

In the constructor, the keyword "this" refers to the object, so this.name is a private global variable that is being set equal to the inputted value for name, in this case "Bob".

Hope this helps!

Write a copy assignment operator for CarCounter that assigns objToCopy.carCount to the new objects's carCount, then returns *thi

ollegr [7]

Answer:

Here is the copy assignment operator for CarCounter:

CarCounter& CarCounter::operator=(const CarCounter& objToCopy) {

carCount = objToCopy.carCount;

return *this; }

The syntax for copy assignment operator is:

ClassName& ClassName :: operator= ( ClassName& object_name)

In the above chunk of code class name Is CarCounter and object name is objToCopy.

Assignment operator = is called which assigns objToCopy.carCount to the new objects's carCount.

This operator basically is called when an object which is already initialized is assigned a new value from another current object.

Then return *this returns the reference to the calling object

Explanation:

The complete program is:

#include <iostream> //to use input output functions

using namespace std; //to access objects like cin cout

class CarCounter { //class name

public: // public member functions of class CarCounter

CarCounter(); //constructor of CarCounter

CarCounter& operator=(const CarCounter& objToCopy); //copy assignment operator for CarCounter

void SetCarCount(const int setVal) { //mutator method to set the car count value

carCount = setVal; } //set carCount so setVal

int GetCarCount() const { //accessor method to get carCount

return carCount; }

private: //private data member of class

int carCount; }; // private data field of CarCounter

CarCounter::CarCounter() { //constructor

carCount = 0; //intializes the value of carCount in constructor

return; }

// FIXME write copy assignment operator

CarCounter& CarCounter::operator=(const CarCounter& objToCopy){

/* copy assignment operator for CarCounter that assigns objToCopy.carCount to the new objects's carCount, then returns *this */

carCount = objToCopy.carCount;

return *this;}

int main() { //start of main() function

CarCounter frontParkingLot; // creates CarCounter object

CarCounter backParkingLot; // creates CarCounter object

frontParkingLot.SetCarCount(12); // calls SetCarCount method using object frontParkingLot to set the value of carCount to 12

backParkingLot = frontParkingLot; //assigns value of frontParkingLot to backParkingLot

cout << "Cars counted: " << backParkingLot.GetCarCount(); //calls accessor GetCarCount method to get the value of carCount and display it in output

return 0; }

The output of this program is:

Cars counted = 12
