在向量的向量中访问类的成员

Question

class item
{
private:
    std::string name;
    double price;
    int quantity;

public:
    void item();
    void setName(string itemName);
    std::string getName();
    void setPrice(double itemPrice);
    double getPrice();
    void setQuantity(int itemQuantity);
    int getQuantity();
};

class list
{
private:
    std::vector<std::vector<item>> notepad;

public:
    bool isEmpty();
    void addList();
    void printLists(bool printTotalPrice);
    void addItem();
    void removeItem();
    void editItem();
    void importList(ifstream& iFile);
    void exportList(ofstream& oFile);
};

Here is where I am having trouble. For my function list::addItem() I want the user to enter a string in order to search the notepad vector's first row elements ONLY in order to find a match.

Something like this...

          for (int i = 0; i < notepad.size(); ++i)
             if (user's entered string) == first element of 'i'th vector.getName() 

... match found

Any ideas on how I could do this?

Answer 1

if ( user_entered_string == notepad[i][0].getName() )

[i] gets the 'i'th vector from notepad .

[0] gets the first item from that result.

.getName() is called on that result.
