any and all help is appreciated, the problem has to with this:

                // Create the Employee class object.
		employee into(name[100], number, date);

		// Create the Production Worker class object.
		productionWorker in(shift, payRate);


but i'm not sure how to fix it.

You haven't defined either of your constructors.

i'm sorry, i'm not entirely sure what are the constructors...
would it be this area?

In employee.h it's the one with the comment that says: // constructor

In the snippet you just posted above the constructor is declared on line 6.

okay so i was able to fix what was wrong with it before.
But now, it doesn't run correctly. The part where it asks for the employee's name has a problem. Also, there seems to be a problem with where it displays an employee's data....
I really have no idea what i did that was so wrong.

here's the first header/class

wait, i think i kinda fixed the first part, where it asks for the employee's name. I got rid of the array and just kept it as a string, but whenever I put a space when I run it, it goes through the whole program then suddenly exits out.
Fumbles93 (10)
ALRIGHT! SO I got the whole thing to work, it displays the employee's data at the end even!
BUT I can't put spaces in the string... It does what i mentioned earlier. This means I can't put in the employee's first name and last name.... Any ideas?

I'm gonna put in the cin.getline cstring, but i don't think that works too well with strings?

Thanks for any and all help, in advance!

Get the entire line then parse it yourself. Look into the substr and find members of std::string.
