Question

Lab 10 Consider the following class definition public Cow(const char" n, double w) Cow(const Cow& c) oid ShowCow) const; double weight display all cow data ation for this class in a epp Sle) and wrte a short program the uses allthe memberfunctions. The prints the name of the function, for example first line of each function should be a cout statement that Because name is a pointer to a character string, you will need to do a DEEP COPY in any function that copies the name of the Cow. This means using new and delete in the appropriate places. A pointer that has been set to nullptr can be passed to delete and delete wil not 1. Project/solution named correctly 2.

Explanation / Answer

Cow.h

#pragma once

#ifndef COW_H

#define COW_h

#include<iostream>

#include<cstring>

using namespace std;

class Cow

{

public:

Cow();

Cow(const char *n, double w);

Cow(const Cow &c);

~Cow();

Cow &operator=(const Cow &c);

void ShowCow() const;

private:

char *name;

double weight;

};

#endif

Cow.cpp

#include "Cow.h"

Cow::Cow(){

weight = 0.0;

}

Cow::Cow(const char *n, double w){

name = new char[100];

strcpy(name, n);

weight = w;

}

Cow::Cow(const Cow &c){

name = new char[100];

strcpy(name, c.name);

weight = c.weight;

}

Cow::~Cow(){

delete this;

}

Cow &Cow::operator=(const Cow &c){

Cow *new_c = new Cow(c);

return *new_c;

}

void Cow::ShowCow() const{

cout<<"Name: "<<name<<", Weight: "<<weight<<endl;

}

main.cpp

#include<iostream>

#include "Cow.cpp"

using namespace std;

int main(){

Cow *c = new Cow();

Cow *c1 = new Cow("Jersey", 100);

cout<<" Through constructor: ";

c1->ShowCow();

c = c1;

cout<<"Assigning: ";

c->ShowCow();

cout<<endl;

return 0;

}
