    Not <string.h> for the string class, just <string>. No standard C++ headers end in .h.

    c:\program files\microsoft visual studio\myprojects\hangman\hangman.h(4) : error C2146: syntax error : missing ';' before identifier 'word'

    You have a missing ; and then something about "missing storage-class" (sorry, don't know about this one).

    The rest of the errors just occur because of the first ones. Fix the first error, and the other 100 will also disappear (magic ).

    Why is the struct extern? You are not linking the header file, you include it in your main program.

    These too are tied together for a reason. The compiler is not recognizing string as a valid type therefore it thinks that is a variable name with no type definition(storage class). The missing ; is because of how you declare variables, aka int a;char b; //ect.

    Thx everyone. I don't know if any of that will fix the problem yet, but I'm gonna try it out.

    As for the 'extern', I was having linking errors b4 and someone told me to use that. If I should take it out what would i do to fix the linking errors?

    God....

    It turns out to be a big problem ....
    Please tell us about the resulte....

    LQQK, Please I want you to check if you realy have string.h in your lib files.... : COULD YOU PLEASE TRY TO WRITE ANOTHER SMALL PROGRAM .. AND INCLUDE STRINGS.H AND TRY TO COMPILE IT ... FOR EXAMPLE:

    Code:
    # include<iostream>;
    #include<strings.h>;
    
    int main()
    {
    string str1= " this is a string";
    cout<< str1<<endl;
    cout<< "let me know what happend.?"
    
    return 0;
    }
    If you got the same problem, that means that you have problem with your ver. of C++...

    it gives me pretty much the same errors as b4.

    it has no idea what a string is for some reason.
