I wrote a program in C# for my discrete mathematics class and it worked absolutely fine. My teacher asked me to submit the code in c++ so she can run it on her mac and so I created a new project and typed the code in. After changing everything required (basic syntax editing and changing Lists to vectors) I tried compiling my program and got these errors. I am using visual studio 2010.

Error 6 error C4430: missing type specifier - int assumed. Note: C++ does not support default-int c:\program files (x86)\microsoft visual studio 10.0\vc\include\xutility 373 1 hw9_2_cpp

I haven't posted the source code yet, because my program compiles successfully using g++ on a linux machine. I get no warnings and errors using that and the execution of program is fine too.

I have no idea why I am getting this error. Could it possible be that I messed up that xutility file?
Do you suggest replacing that file (I really don't want to get into a version mismatch and get screwed up!) ?

Any help/suggestions are highly appreciated.

Thank you,

P.S.: I came back here after an year and now it reads "Contribute New Article" instead of posting a question or something. I couldn't find anything like that and I think it's just that way. I was just wondering as it's not really an article but a question.

No, it means that it can't find the definition of a class that you're using. Is there a line before the first one shown here that says something like "Undefined reference to..."?
