No operator << matches these operands WITH #include<string> - c++

Question

I've been having this same error for two days now: the best version of my code till now is below, and the compiler keeps complaining that "no operator << matches these operands", though I did #include as was suggested in an other topic.
Also I don't know if I'm supposed to put all there headers and stuff in my post cause it's rather crowded that way..
The whole program isn't really all that relevant, I am trying to create a pure virtual function "vector Toestand (int)" (so it should return a vector and have an int as argument). For some reason this never works and that's why I used an other program of which I was certain it did work and I totally stripped it. Still, no luck so far..
I marked the most important pieces that show at what points c++ disagrees with me

Answer 1

Your question can be reduced to this:
#include <vector>
#include <iostream>
int main() {
std::vector<int> v;
std::cout << v;
}
main.cpp:5:19: error: no match for 'operator<<' (operand types are 'std::ostream {aka std::basic_ostream}' and 'std::vector')
And that error pretty much explains the problem. You can't simply send a container to a stream with operator <<. You can either use functionality that someone has written to do this (Pretty-print C++ STL containers), or simply loop over the contents of the vector and do it yourself.
cout << "Testing Tsunami ";
const vector<double>& Toestand = funPtr1->Toestand(10); //get a reference to the vector
for(int i=0; i<Toestand.size(); ++i) //for each element
cout << Toestand[i] << ','; //print the element and a comma
cout << endl;
