Problem: passing a vector of struct by reference

Hi!

I would like to use my vector in a function but the function caller shows that there is a problem. I don´t really know how I can fix this. Thanks for any idea.

Declaration of struct and vector:

struct Person
{
	string sign;
	string firstName;
	string lastName;
	double height;
};

vector<Person> persons;

Functionsprototyp:

void getName(Person[]);

Functionsdefinition:

void getName(Person persons[])
{

...

}

Function caller:

getName(persons);
