Question

Make a simple game using C++ which implements all about Object Oriented Programming (Please make an explanation which of each part in it)

Answer 1

Description of the game:

1. There is two person, one is strong and other one is weak. user can make a choice to choose either strong person or weak person to guess a hidden lucky number.
2. The twist is each person have a health, which is initially 100, but weak person lose 20 health after a wrong guess where as strong man lose 10 health.
3. Both person can make guess till his/her health is greater than 0.

Implementation:

Code:

#include<iostream>
#include<string.h>
#include<time.h> 
using namespace std;

class Person    //base class
{
    protected:
    int health;     //protected member
    public:
    int getHealth()     //public member
    {
        return health;
    }
};

class StrongPerson : public Person  // inheritance StrongPerson is derived class & Persone is base class
{
    protected:
    public:
    StrongPerson()      //constructor 
    {
        health = 100;   //setting health, which is in base class with 100;
    }
    void decreaseHealth()   
    {
        health = health - 10;   //the health will decrease by 10 when this function will call
    }
};

class WeakPerson : public Person    //// inheritance WeakPerson is derived class & Persone is base class
{
    protected:
    public:
    WeakPerson()
    {
        health = 100;   //setting health, which is in base class with 100;
    }
    void decreaseHealth()
    {
        health = health - 20;   //the health will decrease by 10 when this function will call
    }
};

                srand(time(0));
