HashTable error: multiple definition of 'HashTableSavitch::HashTable::HashTable()'

[eiger3970]

Hi cplusplus.com forum people,
I've typed up this code direct from the text book, Absolute C++ Fourth Edition Savitch ISBN-13: 978-0-13-136584-1.
Learning how to make a HashTable.
hashtable.cpp on page 803 gives the error on line 12:
Line 12: multiple definition of 'HashTableSavitch::HashTable::HashTable()'
Line 12: first defined here
Line 12: In function 'HashTable':

Could someone help as I'm learning and this is pushing me over my learning curve :-(

Hi there,

Could you please post your code so we can see what it is that's breaking it?

Not all of us have the book you mention (well I don't anyway), so being able to view the code would help us help you :)

All the best,

NwN

Sorry, only my 2nd post. Here 'tis.
I bolded Line 12 where the error occurs.
