printing object of my objectList

[tukuniata]

hi everybody,
i m having a problem of printing object of my objectList.

In my objectList.hh file i have this:

 class stuffList{
   public:
      void printProperties();
      void addMembers(stuff &item);
      stuffList();
   private:
      vector<stuff> elementList;
      int size;

};

and the implimentation i have this:

stuffList::stuffList()
{

}

void stuffList::printProperties()
{
   stuffList::iterator put;

   for (put = elemantList.begin(); put!= elementList.end(); ++put)
   {
      cout << *put<< endl;
   }

}
void stuffList::addMembers(stuff &item)
{
   elementList.push_back(item);
}

but when compiling the stuffList.cc i m having multiple error saying :
stuffList.cc: In member function 'void stuffList::printProperties()':
stuffList.cc:15: error: 'iterator' is not a member of 'stuffList'
stuffList.cc:15: error: expected `;' before 'put'
stuffList.cc:17: error: 'put' was not declared in this scope

please help me and thanks for your replies

Replace stuffList on line 8 with vector<stuff>

[tukuniata]

i tried that one already and i m having this error:

stuffList.cc:19: error: no match for 'operator<<' in 'std::cout << put.Host::iterator::operator* [with Host = std::vector<stuff>]()'

the line 19 is line 3 on the code below :

  for (put = elemantList.begin(); put!= elementList.end(); ++put)
   {
      cout << *put<< endl;
   }

i m so stuck please help

[helios]

It's complaining because it doesn't know how to print a 'stuff'.

[tukuniata]

i m a bit lost so i have define a function in class stuff or ...? please point me some where

[Zaita]

Your trying to cout an object of type stuff. But it appears you haven't added a method to your stuff class that allows it to be cout'd.

The simpliest method to achieve what you want is to add a function to stuff called print(). Then iterate through your vector and call print on each object.

thanks for your help

[tukuniata]

hi again,
zaita's explaination is so clear but i m so confused again since i m using this different files i have this:

in stuff.cc

void stuff::printProp ()
{
   cout << stuffId << " and " << stuffName << endl;
}

and in stuffList.cc i have this:

 void stuffList::printProperties()
{
//   stuff mystuff;
   vector<stuff>::iterator put;

   for ( put = elementList.begin(); put!= elementList.end(); ++put)
   {
      mystuff1.printProp();
   }

}
 

in the main i have this :

  stuffList staffList;
   staffList.addMembers(fs);
   staffList.addMembers(f2);
   staffList.addMembers( f3);
   staffList.addMembers(f4);
   staffList.printProperties();
 

and the output after run is this :

16 and
16 and
16 and
16 and

i really want to know what am i doing thanks in advance

[mordekai]

In the for-loop you're always calling mystuff1.printProp(); instead of (*put).printProp();

It seems like stuffID of mystuff1 is 16 and the stuffName is an empty string...

[tukuniata]

hey thanks mordekai actually i use your and it is printing the all different stuffId
if i understand it good this means that i m using an iterator (put ) to loop over my list and i m using the same iterator to access funtion from my class (stuff).
still i m wondering why i mnot print the string name (stuffName).
i m going to debugge it again

again thanks for your help
