ベクトルとそのイテレータを使用しています。Inventory.cppと一緒にInventory.hファイルにあります。知りたいのは、直接呼び出すことができるので、push、popなどのベクトルライブラリ関数にアクセスできることです。現時点ではできないためです。誰かがこれで私を助けることができますか?
これが私のコードです:
Inventory.h
//-------------------------------------------------------------------------------
// Inventory.h
//-------------------------------------------------------------------------------
#ifndef INVENTORY_H
#define INVENTORY_H
#include <string>
#include <vector>
using namespace std;
class Inventory
{
public:
//Constructor
Inventory();
//Methods.
string add(string item);
void displayInventory();
void showInventory();
private:
//Data members
vector<string> inventory;
vector<string>::iterator myIterator;
vector<string>::const_iterator iter;
};
#endif //INVENTORY_H
Inventory.cpp
#include "Inventory.h"
#include <iostream>
#include <vector> // To enable the use of the vector class.
#include <string>
using namespace std;
Inventory::Inventory()
{
}
string Inventory :: add(string item)
{
inventory.push_back(item);
return item;
}
void Inventory:: showInventory()
{
char input[80];
cin >> input;
char inventoryRequest[] = "i";
int invent = strcmp (input,inventoryRequest);
//compare the player input to inventoryRequest (i) to see if they want to look at inventory.
if(invent == 0)
{
displayInventory();
}
}
void Inventory:: displayInventory()
{
//vector<string> inventory;
cout<< "You have " << inventory.size() << " items.\n";
cout << "\n******Inventory******";
cout<< "\nYour items:\n";
for (int i= 0; i< inventory.size(); ++i)
cout<< inventory[i] << endl;
}
私がしたいこと:
int main()
{
Inventory inventory;
inventory.push_back();
}
