Declaring a vector in a header file.

[bdwg]

I have two problems.

1. I would like to make a vector with initial length, say 10, within a class. The vector's elements are from another class.

Class Player
{
public:
vector<Item> Inventory(10);
};


The error message is "Expected a ')'" as if it should only be

vector<Item> Inventory();



The code I've written for such is below.


This is the file "Header.h"


#ifndef Item_Test_Header_h
#define Item_Test_Header_h

#include <vector>
#include "Item.h"
#include <string>


using namespace std;

class Player
{
public:

vector<Item> Inventory(10);
};

#endif




This is the file "Item.h"


#ifndef Item_Test_Item_h
#define Item_Test_Item_h

#include <string>

using namespace std;

class Item
{
public:
string name;

Item()
{
name= "N/A";
}
};

#endif






2. My second problem is that I would like to access the elements of this vector within my main function. At first, I didn't declare any initial size of my Inventory vector. It was simply

vector<Item> Inventory;

and I tried accessing the elements in my main file by

Player MC;
Item Ptn;
Ptn.name= "Potion";

MC.Inventory[1]= Ptn;

cout<< Mc.Inventory[1].name;



Using cout just to check if it works, but the console displays "(lldb)"

The code for such follows.



#include <iostream>
#include "Header.h"
#include "Item.h"
#include <string>

using namespace std;

int main()
{
Item Ptn;
Ptn.name= "Potion";
Player MC;
MC.Inventory[0]= Ptn;
cout<< MC.Inventory[0].name;


int end;
cin>> end;
return 0;
}

Declare it as vector<Item> Inventory;, then use an initializer list in the Player constructor to call the Inventory constructor.

Thanks! For anyone who this might help: To fix it, in the constructor I wrote

Player() : Inventory(10)
{
}
