(Solved Homework): need help with a computer science program , here is the code we have been given. we need to create some constructors and a coup…

#include <iostream>
#include <cmath>
using namespace std;

class dog
{
private:
// all data members must be private
string breed;
int weight;

public:
// public constructor declarations
dog()
{
breed = “mutt”;
}
dog(string breed, int weight)
{
this->breed = breed;
this->weight = weight;
}
dog(int weight)
{
this->weight = weight;
this->breed = “mutt”;
}

// public method declarations go here
void setBreed(string b)
{
breed = b;
}
string getBreed()
{
return breed;
}
void setWeight(int w)
{
if (w < 0)
{
weight = 0;
}
else
{
weight = w;
}
}
int getWeight()
{
return weight;
}

// this function will display its breed and weight
void speak()
{
cout << “I’m a ” << getWeight() << ” lbs ” << getBreed() << endl;
}

// This function will interchange breeds and weights
void switchBodies(dog& type)
{
string tempBody;
int tempwt;

tempBody = type.getBreed();
tempwt = type.getWeight();

type.setBreed(this->getBreed());
type.setWeight(this->getWeight());
this->breed = tempBody;
this->weight = tempwt;
}

dog mateWith(dog wimpy)
{
int weight;
weight = (wimpy.getWeight() + getWeight()) / 2;
dog puppy;
puppy.setWeight(weight);
puppy.setBreed(getBreed() + “-” + wimpy.getBreed());

return puppy;
}

void bite(dog& type)
{

type.setWeight(type.getWeight() – 10);
type.setBreed(this->getBreed());

this->setWeight(this->getWeight() + 10);
}

void operator++(int)
{
this->setWeight(getWeight() + 100);
}
};

int main()
{
// step 1: set up dog class, implement default constructors
dog bonny;
dog wimpy;

// step 2: set two different parameterized constructors
dog fido(“rottweiler”, 200);
dog snuffles(15);

// step 3: create “set” methods
bonny.setBreed(“pit bull”);
bonny.setWeight(500);

wimpy.setWeight(-300);

// step 4: create a speak method
bonny.speak(); // I’m a 500 lbs pit bull
wimpy.speak(); // I’m a 0 lbs mutt
fido.speak(); // I’m a 200 lbs rottweiler
snuffles.speak(); // I’m a 15 lbs mutt

// step 5: switch bodies!
bonny.switchBodies(fido);

bonny.speak(); // I’m a 200 lbs rottweiler
fido.speak(); // I’m a 500 lbs pit bull

// step 6: love is in the air
dog puppy;
puppy = fido.mateWith(wimpy);

puppy.speak(); // I’m a 250 lbs pit bull-mutt

// step 7: uh oh, they’re fighting…
puppy.bite(fido);
puppy.speak(); // I’m a 260 lbs pit bull-mutt
fido.speak(); // I’m a 490 lbs pit bull-mutt

// step 8: let’s feed that puppy
puppy++;
puppy.speak(); // I’m a 360 lbs pit bull-mutt

return 0;
}
