C++

Write a class called Zombie. It should have a method called speak() that prints \"Braaaainss!\". It should have a static variable that keeps track of how many Zombie objects have been created. When a Zombie is created, its constructor will need to increment the value in the static variable. In order to keep the count accurate when Zombies are destroyed, you will need a destructor to decrement the value in the static variable.

In your main function you should declare a vector of Zombie-pointers. You should give the user a menu in a loop. The options should be to: 1) create a new Zombie; 2) destroy a Zombie; 3) print the number of existing Zombies; 4) tell all existing Zombies to speak; or 5) quit. When a user chooses to create a new Zombie, you should dynamically allocate the new object and push its pointer onto the vector. When a user chooses to destroy a Zombie, you should pop the last Zombie pointer off the vector and deallocate the memory for that Zombie.

Solution

Zombie.hpp

#include<iostream>

#ifndef Z_HPP

#define Z_HPP

using namespace std;

class Zombie

{

private:

static int total_zombie;

public:

Zombie(); //Constructor, adds to static variable

~Zombie(); //Destructor, subtracts from the static variable

void speak(); //Repeats what zombies say.

void add();

void del();

int total();

};

#endif

int Zombie::total_zombie = 0;

Zombie::Zombie()

{

add();

}

Zombie::~Zombie()

{

del();

}

void Zombie::speak()

{

cout <<\"Braaaainss!\" <<endl;

}

void Zombie::add()

{

total_zombie++;

}

void Zombie::del()

{

total_zombie--;

}

int Zombie::total()

{

return total_zombie;

}

Zombie.cpp

#include<iostream>

#include <vector>

#include \"Zombie.hpp\"

using namespace std;

void main_menu();

int main()

switch(ch)

{

case 1: cout <<\"\ ZOMBIE CREATED!!!!!!\" <<endl;

eater.push_back(new Zombie); //creates new zombie & puts in vector

break;

case 2: if(eater.empty())

cout <<\"\ There is no zombies to kill \" <<endl;

else

{

size =eater.size();

delete eater[size-1];

eater.pop_back();

cout <<\"\ KILLED\" <<endl;

}

break;

case 3: size =eater.size();

case 4: cout <<\"\ CAN YOU HEAR\" <<endl;

size =eater.size();

for (int i = 0; i<size; i++)

eater[i] ->speak();

break;

}

}while (ch !=5);

cout <<\"\ GAME OVER\" <<endl;

return 0;

}

void main_menu()

{

cout <<\"1. Create a Zombie!\" <<endl;

cout <<\"2. Destroy a Zombie!\" <<endl;
