for (vector<pair<int, int> >::const_iterator pos =

NOooo problem.

// -------
#include <iostream>
#include <ostream>

int main(){
std::cout << "Hello World" << std::endl;
return 0;
} // main()
// -------

Another example:

// -------
#include <iostream>
#include <ostream>

class Hi{ public:
void Say( std:stream &out ){
out << "Hello World" << std::endl;
return;
}
};

int main(){
Hi Ima;
Ima.Say( std::cout );
return 0;
} // main()
// -------

Your turn.

If that's vector<pair< , > > then I must be really blind as I can't see
it.

In the message body (s)he said, "It is best to show me some examples.". So, I
showed some examples! I saw NO question about anything IN the post!

template <class A, class B> class pair{ public:
A a;
B b;
};

For vector you do.... Oh wait, did you actually mean 'std::vector'? You
should state that!
