Ok so, this IS a homework assignment. I'm not asking for the answer. I need help on how to get started. Any help would be greatly appreciated. The assignment is to revise some code from a previous assignment, but I'm having trouble with figuring it out. The instructions are:
You will revise your code from Programming Assignment 4 in the following ways:
1. Place your fairy data into a text file. You will open the file and read it in order to construct your fairies.
2. Make all inherited methods virtual. You will call all methods using a base class pointer.
3. Dynamically create your fairies and store the pointer to each fairy in a vector. The vector type is the base class.
4. You may access each fairy from the vector using either the brackets operator, i.e., array access, or an iterator.
5. When you are finished, delete each fairy object.
The original code below creates a game where the user encounters different fairies. Each fairy acts differently. Some reward points, some take away points. I'm just having trouble revising my code. Can anyone help please?
Here is my code (its rather long)
main
#include <stdio.h>
#include <iostream>
#include "Fairy.h"
#include "GoodFairy.h"
#include "EvilFairy.h"
#include "EquiFairy.h"
using namespace std;
int main()
{
GoodFairy f1("Bob");
EquiFairy f2("Joe");
EvilFairy f3("Billy-Bob");
GoodFairy f4("John");
EquiFairy f5("Joe-Bob");
int totalPoints = 0;
totalPoints += f1.talkToFairy();
totalPoints += f2.talkToFairy();
totalPoints += f3.talkToFairy();
totalPoints += f4.talkToFairy();
totalPoints += f5.talkToFairy();
cout << "Your total score is: " << totalPoints <<endl;
if(totalPoints < 0)
cout << "COMMON BRO! IN THE NEGATIVES??" << endl;
else if(totalPoints == 0)
cout << "I give you credit for trying" << endl;
else if(totalPoints > 0)
cout << "OH YES! THERE WE GO! A TRUE GAMER, SCORIN BIG!" << endl;
else
cout << "error has been encountered yo, try again!" << endl;
cout << endl;
cout << "Thank you for playing!" << endl;
return 0;
