Compiling error.

Kniggits (10)
I have a program that I have fully working if I only use 1 .cpp file and .h file together.

Problem is I have to link 2 .cpp files and the header file.


when I try to compile it gives me there errors 

1>wizard.obj : error LNK2005: "class Wizard wiz2" (?wiz2@@3VWizard@@A) already defined in p2.obj
1>wizard.obj : error LNK2005: "class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > cursestring" (?cursestring@@3V?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@A) already defined in p2.obj
1>wizard.obj : error LNK2005: "class Wizard wiz1" (?wiz1@@3VWizard@@A) already defined in p2.obj


Any ideas why this is happening?

Oh, and I'd include the files but it's too much to post. I'll try in a reply or something.

That's all of it. Hopefully I'm not going against the rules doing this

You appear to be missing a header guard on wizard.h and it's being included twice.

Also, a using statement in a header file is a not a good idea as in wizard.h line 2:

using namespace std;

Doing this pulls in the entire std namespace so that every time you include wizard.h everything in the std namespace comes along for the ride. Sooner or later this will lead to identifier name conflicts. In a header file it is best to leave out the using statement and fully qualify the identifiers you need such as std::string instead of string.
