Help with classes

[Antone333]

could someone please direct me to a good place for me to work on classes? i am working on a very simple text based game and i put in an inventory system. using if statements. i know its a bad way to do it. but thats how i knew how to so i did it and it works. but i want to work on doing this the "Proper" way. now i know it will probably still be far from good but just an improvement from what i have.

i know some basics on classes but dont know how to apply to what i want to use them for.

thanks for the help!

void PrimaryHand()
{
     if(PrimaryHandItem == 0)
     {
          PrimaryHandName = "No Item";
          PrimaryHandHP = 0;

          PrimaryHandATT = 0;
          PrimaryHandDEF = 0;
     }
     else if(PrimaryHandItem == 1)
     {
          PrimaryHandName = "Sword";
          
          PrimaryHandHP = 10;
          PrimaryHandATT = 2;
          PrimaryHandDEF = 1;
     }
}

This is a
simple idea

Eyenrique-MacBook-Pro:Desktop Eyenrique$ ./Items 
Sword
HP: 10
att: 2
def: 1

Bow
HP: 9
att: 2
def: 0

Ender pearl
HP: 5
att: 0
def: 1

//Items.cpp
//##

#include <iostream>
using std::cout;
using std::endl;

#include <string>
using std::string;



class Item{
	public:
		int id;
		string item_name;
		int hp;
		int att;
		int def;
};//end class Item


int main(){

	const int SIZE=3;
	Item inventory[SIZE]; 

	inventory[0].id=0; 
	inventory[1].id=1;
	inventory[2].id=2;

	for(int i=0;i<SIZE;i++){
		switch(inventory[i].id){
			case 0:
				inventory[i].item_name="Sword";
				inventory[i].hp=10;
				inventory[i].att=2;
				inventory[i].def=1;	
			break;
			case 1:
				inventory[i].item_name="Bow";
                                inventory[i].hp=9;
                                inventory[i].att=2;
                                inventory[i].def=0;

			break;
			case 2:
				inventory[i].item_name="Ender pearl";
                                inventory[i].hp=5;
                                inventory[i].att=0;
                                inventory[i].def=1;

			break;

		}//end switch
	}//end for

	//print your inventory
	for(int i=0;i<SIZE;i++){
		cout<<inventory[i].item_name<<'\n'
			<<"HP: "<<inventory[i].hp<<'\n'
			<<"att: "<<inventory[i].att<<'\n'
			<<"def: "<<inventory[i].def<<'\n'<<endl;
	}//end for

return 0; //indicates success
}//end main

ok. thanks but a lot of that is more advanced then what i am capable of. what it looks like to me is pretty much replace the: "if(PrimaryHandItem == 0)" with the "case 0;"

would that be a true statement or not?

and the other part i am not familiar with is the
for(int i=0;i<SIZE;i++)
i guess its fairly straight forward to me it looks like an if but it only happens if parameters are true. im not sure to be honest though.

[eyenrique]

well first off,
switch and for loop are
basic statements i
think that you should
learn more about
control structures;
(conditional and
repetition)

switch its a multiple-selection
statement that is helpful in
some cases instead of
if or if-else;

for -for loop- is
a repetition statement that
specifies the number of
iterations in a single
line of code.


Best regards.

To be honest, I don't think that's the greatest example of using classes to find a data-driven solution, as opposed to a hardcoded one.
As OP has already noticed, it's not really any different from his original code (

what it looks like to me is pretty much replace the: "if(PrimaryHandItem == 0)" with the "case 0;"

).

If you want, I can write a quick example that would make more sense in my eyes, however, you may not understand it.

i would appreciate it if you could. the more different ways i can see it done the better. right?
