A vector of objects

[GamerMax5]

Simulating a shopping list of some sorts is what I'm trying to do.

I have a class called item that looks like this:

class item{
private:
    std::string itemName;
    std::string itemDesc;
public:
    item();
    ~item();
    item(std::string newItemName, std::string newItemDesc);
    std::string getItemName(){return itemName;}
    std::string getItemDesc(){return itemDesc;}
    void setItemName(std::string newItemName){itemName = newItemName;}
    void setItemDesc(std::string newItemDesc){itemDesc = newItemDesc;}
};

And yes I know about the using statement but I don't use it.

When creating an instance of the item class, I'll mostly be using the constructor with the 2 argument signature.

Now in my main function I want to declare a vector that will hold any instance of the item class I pass to it. Then I want to be able to access any object inside the vector so that I can get it's attributes. This is what I got so far:

    item milk("Milk", "A gallon of milk.");
    std::vector<item> shoppingCart;

This is where I'm lost at.

I'm guessing that when I want to add an object to the vector, I use the push_back function passing the instance? And for accessing the elements of the vector, would I use an iterator?

Thanks in advance for any help. It's greatly needed.

Yes and yes. Or you can use indexing.

Okay well how would I go about accessing the public members of the class though the instance located in the vector? Like instance milk is stored in shoppingCart[0]. How would I access the getItemName class member from the instance?

[CornedBee]

shoppingCart[0].getItemName()

Which method would be better? Indexing or iteration?

For getting at all of them, I'd say iterators. For accessing a specific one, indexing.
