Calling function from a class - Error C2660

patriic48 (100)
I can´t figure this problem. I have tried with different approaches and have no result. The compler complains and gives the error 2660. What am I doing wrong?

Most of us don't memorize error codes.

What is the actual error message?

What line is the error on?



EDIT:


okay I see it in the comments of the code.

konto.skriv_kontolista(); //This line gives the error error C2660: 'Konto::skriv_kontolista' : function does not take 0 arguments

The error tells you exactly what the problem is. You have a function called 'skriv_kontolista'. That function takes a vector as a parameter. So when you call it, you have to give it a vector to work with.

On this line, you are calling it, but your are not giving it any vector, so it's an error. The function takes 1 parameter and you are giving it 0.

How and which parameter?

I´ve tried everything without any result. For example

konto.skriv_kontolista(vector<Konto>&konton); or konto.skriv_kontolista(konton);

nothing seems to work.

you'll need to create a vector of kontos and then pass it to the function 

1
2
3
4
5
 
std::vector<konto> kon_vec;
///load kontos into your vector or just pass it to your vector as you intend

konto.skriv_kontolista(kon_vec);///for your information you need to call this function
                                      ///on a class instance not the class name "your calss is named konto"

My vector is created in another class, like this

1
2
3
 
class Bank {
public:
	vector<Konto>konton;


I have to use this vector, is it possible?

I have another function and this one runs without a problem

My vector is created in another class, like this yeah it's possible to use it since its a public member but i'd advice you not to use such a routine as they increase interdependence between classes for no reason , a local vector object could suffice for what you intend.
