Passing Object Array into a Function

I simply cannot figure this program out (nor why I am going in debt paying professors to "teach" me). Our assignment begins with reading a data from a file and storing it in an object array and then displaying the contents of that array.

When I compile the program in MS Visual Studio I get the following error:

error C2664: 'printArray' : cannot convert parameter 1 from 'Investment [1000]' to 'Investment'
1> No constructor could take the source type, or constructor overload resolution was ambiguous

I do not understand what is causing this error or how to fix it.

Any help would be appreciated.

Investment.h code

#include <string>

using namespace std;

class Investment
{
	private:
		string lastname;
		float amount;		
		float rate;			
		int month;
		int day;
		int year;

	public:
		Investment();
		Investment(string n, float a, float r, int m, int d, int y);

		void setName(string n); 
		void setAmount(float a);
		void setRate(float r);
		void setMonth(int m);
		void setDay(int d);
		void setYear(int y);

		string getName();
		float getAmount();
		float getRate();
		int getMonth();
		int getDay();
		int getYear();
		
		float getValue(int n);
		void printDate(ostream& outf);

};

Ok you have to make one change,

in Project2.cpp

.
.
.
using namespace std;

#define N 1000

//void printArray(Investment, int); //HERE
//make it this way
void printArray(Investment [], int);


int main()
{
.
.
.
