Declaring vectors in a C++ header file

Question

I am having some trouble with vector declarations in the header file of a C++ class I am making. My entire header file looks like this:

#ifndef PERSON_H
#define          


        

Answer 1

You're missing the namespace:

std::vector

Answer 2

In my case, adding the namespace did not work, however, I was missing the

#include <vector>;

Answer 3

You need to put 'std::' before 'vector' just like you did with string.
