stl usage question

[Guest]

I have an object a

class object
{
private:
string streetname ;
vector listofhomes ;
}

i want to use STL template to build a program like

this class will have a

{ reed street,
list of houses in this street( names).
}

I want this to be collection. Like
{ streetname, list of houses)
(streetname, list of houses)...

How do i do it ?


Thanks in advance.

I have an object a

class object
{
private:
string streetname ;
vector listofhomes ;
}

That's almost a class declaration. (You need a semicolon after
the closing brace.) It is not an object.

Read through your writing before you publish it. People are
more likely to understand your question if it makes sense.

this class will have a

{ reed street,
list of houses in this street( names).
}
What?

I want this to be collection. Like
{ streetname, list of houses)
(streetname, list of houses)...

That's a very odd syntax. What does it mean?

How do i do it ?

Overload `operator >>' for objects of your class type. In your
`main ()' function, declare an object of type std::vector <object>.
Use std::copy, std::istream_iterator and std::back_inserter to read
the objects from a stream (either cin or an istream object you have
created) and insert them into the vector.

Thanks in advance.

vector requires a template argument,

}

vector<object> collection;

Alos I think you should have a more descriptive name
for your class than 'object', perhaps 'Street' or
'Houses', etc.

Which C++ book(s) are you reading?

That's almost a class declaration. (You need a semicolon after
the closing brace.) It is not an object.

Also needs a type parameter after vector, e.g.

class Street
{
private:
string streetname ;
vector<int> listofhomes ;
};
