C++ OOP can't find item by ID
Hi every1!
Thats my code that used to work before I've added some attributes to my items.
void manager::EditStockItem()
{
ListStock();
{
string z;
bool found;
cout<< endl<<"<===================================================>"<<endl<<endl;
cout << "Enter ID of the Stock Item you want to edit" << endl<<endl;
cin>>z;
found = false;
vector <Item*>::iterator iter = theStock.begin();
for(iter = theStock.begin();iter != theStock.end();++iter)
{
if (z == ((*iter)->getStockID()))
{
found = true;
break;
}
}
if(found)
{
system("cls");
char choice;
bool valid = false;
for(;;)
{
system("cls");
do
{
cout << " Edit details of "<<z<<endl;
cout << " 1. To edit ID\n";
cout << " 2. To edit Title\n";
cout << " 3. To edit Publisher\n";
cout << " 4. To edit Price\n";
cout << " 5. To Cancel\n";
cin >> choice;
if(choice == '5')
{
ShowAdminMenu();
}
else if(choice < '1' || choice > '4')
{
cout << "\nNot a valid char!\n\n";
char aChar;
cout << endl << "Enter any character to continue .. " << endl;
cin >> aChar;
system("cls");
}
else
{
valid = true;
}
}
while(!valid);
cout << "\n";
switch(choice)
{
char aChar;
case '1':
{
cout << "Enter new ID" << endl;
string newStockID;
cin.sync();
getline(cin,newStockID);
(*iter)->setStockID(newStockID);
ListStock();
}
cout << endl << "Enter any character to continue .. " << endl;
cin >> aChar;
break;
case '2':
{
cout << "Enter new Title: " << endl;
string newTitle;
cin.sync();
getline(cin,newTitle);
(*iter)-> setTitle(newTitle);
ListStock();
}
cout << endl << "Enter any character to continue .. " << endl;

Heres the Stock vector
void manager::BuildStockVector()
{
theStock.push_back(new Book("SBK010","978-0-307-47427-8","A Tale of Two Cities","Penguin Classics","General","345","12"));
theStock.push_back(new Book("SBK020","325-0-412-45527-4","The Da Vinci Code","Random House","General","237","14.25"));
theStock.push_back(new Book("SBK011","978-0-307-47427-3","Copy of the book 'A Tale of Two Cities'","Penguin Classics","General","340","12"));

}It's askin to enter ID of the item to edit but when I do so it returns NOT FOUND...I'm newbie to C++ so not sure if I have to upload any other files for a full picture...
Oh another thing .. The classes are (controller/Stock/Item/Publication/Books) ( controller/Stock/Item/Publication/Journals) ( controller/Stock/Item/av/Video) and ( controller/Stock/Item/av/MusicCD)
I assume outputting z went okay, but you got junk for the (*iter)->getStockID() stuff. If so there other possible problems besides something wrong with getStockID():
--the syntax you're using to call getStockID() isn't working
--the process to enter information into the vector isn't working so the contents of the vector aren't what you think they are
Who knows what it is at this point. But we do know it's probably not what/where you thought it was in the first place. It was the obvious first place to look, but it didn't pan out. So, I'd go back earlier in the program, try to add a single item to the vector and then try to output the information, including at least a call to getStockID(). That should help you take the next step to figuring out where the problem is.
You're right Z is fine but (*iter)->getStockID() displays nothing...absolutely nothing..I'm thinking about earlier stage and ....Be4 classes were controller/stock/item/book and it was working fine.. But later I've added another class so now I have like controller/stock/item/publication/book, but I still can't imagine where the problem might be...
How do you display the contents of the vector of stock when you display it successfully, and where are you checking the display?
Post the header file for the manager class, please.
I use getAllDetails() to display The Stock and if I add new item befor this function I can see that in a list..here's the code
#pragma once
#include <vector>
using std::vector;
class manager
{
private:
string CurrentUserID;
vector <customer*> theCus;
vector <Item*> theStock;
void BuildCustomerVector();
void BuildStockVector();
void BuildAdminVector();
void Login();
void aLogin();
void uLogin();
void AddUser();
void AddAdmin();
void AddCustomer();
void ListUsers();
void EditUser();
void ListStock();
void ChangePass();
void AddStock();
void AddBook();
void AddJournal();
void AddVideo();
void AddMusicCD();
void EditStockItem();
void HireInfo();
public:
manager(void);
~manager(void);
void ShowUserMenu();
void ShowAdminMenu();
};Ok. I don't see getAllDetails() in code posted so far. theStock is listed as a private member variable of the manager class. How does getAllDetails() get access to theStock?
Please post header file for the Item class, too, so getStockID() declaration can be viewed.
Just like you included the vector header file for the manager class to use, you will need to include the header files for STL string class, the Item class and the customer class for the mangager class to use in the header file. I don't seen those headers included in the mangager class. That may be the easiest thing to check out.
This simple function returns all details apart from ID ....
void manager::ListStock()
{
system("cls");
cout << endl << "Stock Items" << endl << "<=====================>" << endl;
vector <Item*>::iterator iter = theStock.begin();
for(iter = theStock.begin();iter != theStock.end();++iter)
{
cout<<(*iter)->getStockID() << endl;
(*iter)->getAllDetails();
cout << endl << "==================" << endl;
}
cout << endl << "End of List" << endl;
}So if you call ListStock() and it correctly prints out all the attributes except the ID of the Item pointers in theStock, then please post the Item class header file and the implementation of getStockID().
Just to remind it goes :manager/Stock(abstract)/Item/publication/book .
There's nothin in Stock.cpp and I'm not sure if I need this at all..But it's there and it works.
This is header file for book.cpp
#pragma once

To be honest I'd send everything after a whole day of useless trying..
Welcome to the world of runtime debugging. It can be long and tedious.
Does the non default Book constructor assign SID to StockID? Posting the entire definition of that constructor wouldn't hurt.
Please post the call you used to getAllDetails() and the version of getAllDetails() used (it's declared as virtual defined as void in class Item, so I assume it has a different definition in class Publication and class Book).
Right..Here's what I'll do (because my brain is stalled and I've already made some modifications trying to solve it )... I'll upload most of it so it is easier to trace the process..Here goes...

Assumption: You are doing a copy/paste when you post your code.
C++ is case sensitive. So the variable StockID in class Item is different than the variable called stockid declared in class publication. Therefore publication class publication and class Book have both StockID and stockid. In Book the non default constructor assigns the first input string (inadviseable also called StringID) to stockid inherited from publication, not the class variable StockID inherited from Item.
The getStockID() function in class book returns StockID(), not stockid, but even that wouldn't matter because in manager::EditItem, you are using an Item pointer to call a non virtual function, meaning it will call the version of getStockID() in Item, not the version of getStockID() in class Book. Unfortunately since the Item default constructor doesn't give StockID a value and the non default constructor of Book also doesn't assign a value to StockID so StockID has no value when the Item version of getStockID() is called.
I recommend you remove all variable declarations from publication and Book that are inherited from Item and only declare any new variable attributes you want those classes to have. That means the Book non default constructor will assign the first string passed in(PLEASE call it somehting other than StockID) to the variable called StockID inherited from Item. And beware when calling methods from base class pointers, as the virtual functions will be of the class stored as a base pointer not the base class methods, but the non virtual functions will be the version in the base class not the derived class version(, and any method in the derived class not declared in the base class won't be available to be called through the base class pointer at all).
I've removed all repetitive attributes from publication and Book.. Now I'm getting errors error C2661: 'Book::Book' : no overloaded function takes 8 arguments. I've tried to make "few" more changes but.. no idea where to look for solution..
