ok, the program works but i need help with the main, any help would surely be appreciated! :)

[ledzepdoors1]

ok i believe i dont need all of that in main but just a simple
Employee employee;
employee.print();
system("pause");

but why still doesnt it work?

What exactly are you trying to do?

[TheNoobie]

1.) Put your code in the [ code ] brackets.
2.) Look up what polymorphism is.

[ledzepdoors1]

i just want to be able to insert some information about an employee and display the birthdate and other information. when i try it the first way as i show, it gives me two errors, one being that the parameter doesnt hold 8 parameters and the second, birthDate isnt part of employee. is it because birthDate is declared as private? ive been having trouble with this and ive looked it up many times already.

[ledzepdoors1]

heres my date class:

class Date
{
public:
Date( int = 1, int = 1, int = 1900 );
void setDate(int, int, int);
static bool leapYear(int);
bool endOfMonth(int) const;
void print() const;
~Date();
int getMonth() const;
private:
int month;
int day;
int year;

static const int days[];
};

const int Date::days[]=
{0,31,28,31,30,31,30,31,31,30,31,30,31};

Date::Date( int m, int d, int y)
{
setDate(m, d, y);
}
void Date::setDate(int m, int d, int y)
{
month = (m >= 1 && m <=12) ? m : 1;
year = (y >=1900 && y <= 2100) ? y: 1900;

if (month == 2 && leapYear(year))
day = (d >=1 && d <= 29) ? d : 1;
else
day = (d >= 1 && d <= days[month]) ? d : 1;
}
bool Date::leapYear( int testYear )
{
if (testYear % 400 ==0 ||
(testYear % 100 != 0 && testYear % 4 == 0))
return true;
else
return false;
}
bool Date::endOfMonth(int testDay) const
{
if (month == 2 && leapYear(year))
return testDay == 29;
else
return testDay == days[month];
}

void Date::print() const
{
cout << month << '/' << day << '/' << year;
}

Date::~Date()
{
cout << "Date object destructor for date ";
print();
cout << endl;
}
int Date::getMonth() const
{
return month;
}

Put your code in tages [code]...[/1code]
remove the 1.

You need a default constructor for employee in your class declaration.

Employee();

[ledzepdoors1]

ok i will try that :) thank you

Tell us the compiler errors http://www.cplusplus.com/forum/articles/40071/#msg216270

If it doesn't make sense to have a default constructor, you should not have it. (¿how will you initialise the members?)

Also you should not include cpp files, just the headers.
