Vectors

[grinning_dog18]

Hi, I am quite new to c++ and finding it hard to get used to the added functions - I used to use Java..
Anyway I have to create a class house which has a number of member variables that represent a vehicle which I assume is like this
class house
{
string type;
string colour;
string number;
}

And then make a suitable constructor and method toString to return output

string house::toString()
{
string("House is ( " + type + ", " +
colour + ", " +
number +")");
}

but when I do this it says string house::toString() 'expected primary-expression'... I'm so confused!
After I've done this I need to make house into a vector so I can have additional houses - apparently I need to make a class like this
class HouseGroup
{
private:
vector<string> House;
public:
Void addHouse(House v);
string toString();
}

string toString is meant to create a string representation of the entire collection.. ?

If anyone could explain to me how a vector works and how I would go about it I'd be very grateful! Thanks

1) You have declared a vector, but you do not do anyting with it.

2) is toString() supposed top be a member of house or HouseGroup ?
(you declared it in Housegroup, but implement it in house).

3) toString() should return a string.

house::toString() says that the toString function is a member of house and which in your case its not I changed a couple of things.what in your case does vector mean, the only vector i know is a line with an origin,direction and length?.You might want to check out CString classes. I would strongly advise a book on C++ in 24 hours, the fastest way to learn just the basics.

class house
{
string type;
string colour;
string number;
string toString ();<------------added as a member of house
};<------------added

string toString()<-------------changed
{
string("House is ( " + type + ", " +
colour + ", " +
number +")");
};<------------added

class HouseGroup
{
private:
vector<string> House;
public:
Void addHouse(House v);
string toString();
}

string toString()<-------------changed
{
string("House is ( " + type + ", " +
colour + ", " +
number +")");
};<------------added

It used to be better before, except that you had to return something from the function.

string house::toString()
{
  return string("House is ( " + type + ", " + colour + ", " + number +")");
}

Actually, that will probably cause a compile error. To avoid it, move the "string(" close paren to just after "House is ( " rather than the end of the line.
