above explanation is correct?

If the someMethod() in Sub class is

virtual void someMethod(int i = 1){cout<<"in Sub class"<<endl}

when the compiler runs ref.someMethod(); statement,what is the output?
In VS 2005,the output is "in Super class". I feel it is hard to understand,I believe the right result is "in Sub class".

std::string strText;
std::stringstream ssBuf;
ssBuf.imbue(std::locale::classic()); // This line tells the stringstream to use the classic locale
ssBuf<<55555;
ssBuf>>strText;

std::string strText;
std::stringstream ssBuf;
std::locale l;
l = l.combine<std::numpunct<char> >(std::locale::classic());
ssBuf.imbue(l);
ssBuf<<55555;
ssBuf>>strText;
