hey guys/gals im havin a problem in my test.cpp file in line 65 where i have cout << date.print();

the compiler says:
test.cpp: In member function âvoid Test::print() constâ:
test.cpp:67: error: no match for âoperator<<â in âstd::cout << ((const Test*)this)->Test::date.Date::print()â

where am i making a mistake because i have <iostream> and using namespace std; where i need it? any suggestions?

//class member functions
#include "date.h"

Date::Date()//default constructor
{
	month = 1;
	day = 1;
	year = 2010;
};

void Date::setDate()

	cout << "What date was this test performed(mm/dd/yyyy): ";
	cin >> setw(2) >> month;
	cin.ignore(1);
	cin >> setw(2) >> day;
	cin.ignore(1);
	cin >> setw(4) >> year;
	
	month = checkMonth(month);
	day = checkDay(day);
	year = checkYear(year);
}

int Date::checkMonth(int testMonth)
{
	if(testMonth < 0 || testMonth > 12)
	{
		cout << "Invalaid month(" << testMonth << ") set to 1.\n";
		return 1;
	}else
		return testMonth;
}

int Date::checkDay(int testDay)
{
	int daysPerMonth[13] = {0, 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31};

	if(testDay > 0 && testDay <= daysPerMonth[month])
	{
		return testDay;
	}else if(month == 2 && testDay == 29 && (year % 400 == 0 || (year % 4 == 0 && year % 100 != 0)))
	{
		return testDay;
	}else
	{
		cout << "Invalid day(" << testDay << ") set to 1.\n";
		return 1;
	}
}

int Date::checkYear(int testYear)
{
	if(testYear > 2010 || testYear < 1990)
	{

In order to print something using a cout statement your function must return something (a string, int, double, etc). Your print() method is void. Just call your print method on its own without sending it into cout.
