Error showing up and no clue what it is referencing: symbol(s) not found for architecture x86_64

I'm new to c++ and am using Eclipse on my Mac osX. This error (below) has come up and I have no idea why. Can anyone help? Is there something wrong with my code? Please help, I am a newbie.

error:

[long double main]

You declared createtable() as
void createtable( );

But then, in your function definition, you wrote
void createtable( EmployeeRec employees[ ] )

The declaration on line 15 should match with the function definition...(and then in main(), you're calling it wrong).

[Azagaros]

You have a prototype not matching the function.

// the prototype 
void createtable( );

// the function
void createtable( EmployeeRec employees[ ] )

if you want a c++ compiler to see them as the same thing they need to be exactly alike. In C++ you can have more than one function with the same name with different definitions and this is the case you created, thus the function isn't seen by the linker.

Wow. I feel like an idiot. Thanks for your quick responses guys!
