im new with C++ . i was in java but now im learning C++ and i am not very good at it . i am making a program about spam and ham emails . i have all the files in the same directory . i created Ergasia1.cpp , Ergasia1.h , Feature.cpp , Feature.h
but when i compile Ergasia1.cpp i got errors like :
1. " In file included from Ergasia1.cpp "
2. " Ergasia1.h [Warning] extra tokens at end of #endif directive "
3. "Feature.h [Warning] extra tokens at end of #endif directive " (after this error there are several errors like this " [Linker error] undefined reference to `Feature::getDescription()' "
4. " Feature.h ld returned 1 exit status "
and when i compile Feature.cpp i got errors like :
1. " In file included from Feature.cpp "
2. " [Linker error] undefined reference to `WinMain@16' "
3. " Feature.h ld returned 1 exit status "
