Hello,

I made a vector of a string and added a member function of an item class getName, witch just returns the name:

[source lang="cpp"]string Item::getName() {

return m_Name;
}[/source]

so i initialized the vector and iterator like so:

[source lang="cpp"]vector<string> inventory;
vector<string>::iterator iter;[/source]

and then:

[source lang="cpp"]inventory.push_back(sword.getName());[/source]
Now my question is how to print the names of the items. the item class:

[source lang="cpp"]class Item{

public:
enum Type{WEAPON, ARMOR, CONSUMABLE, TRASH};
Item(string name, Type type, int rarity, int value);
string getName();

private:
Type m_Type;
string m_Name;
int m_Rarity;
int m_Value;
};

Item::Item(string name, Type type, int rarity, int value): m_Name(name), m_Type(type), m_Rarity(rarity), m_Value(value) {}

string Item::getName() {

return m_Name;
}[/source]

Now what i want to do is make an inventory class that handles adding dropping, equipping, and listing all the items in the inventory. I have no idea how to print the names though. all help is appreciated.

You can access each string in the vector with either:
inventory.at(0); //Get the first string in the vector, or throw an exception if out of range.
inventory[0]; //Get the first string in the vector, or hopefully crash if out of range.
inventory.back(); //Get the last string in the vector, or hopefully crash if the vector is empty.
inventory.front(); //Get the first string in the vector, or hopefully crash if the vector is empty.


(always check inventory.empty() or inventory.size() before accessing an element)

To print out everything:

By index:

for(unsigned int i = 0; i < inventory.size(); i++)
{
std::cout << inventory << std::endl;
}

With iterators:
typedef std::vector<std::string>::iterator StrVectorIterator;
for(StrVectorIterator myIt = inventory.begin(); myIt != inventory.end(); myIt++)
{
std::cout << (*myIt) << std::endl;
}

Iterators are designed to be similar to pointers; you don't need to create an iterator until you actually need it - infact, the iterators will be invalidated if you operate on the vector after getting the iterator.

Servant, i tried both those ways but i get an error on the output operator saying operator "<<" matches these operands. i think i need to overload a the operator, but the book i learned from was kinda confusing when it taught that.

oh my god, someone told me that the sting was already in iostream so i never needed to include it. god that pisses me off, all i needed to do was include string. well that's for the help.
