First make sure you have setup your environment variables, then put this in the hello.cpp file, i'm using images because i think this forum has a bug, it wont let me type iostream.h
to compile goto command type cd c:\Location of your source file (c:\mycode)
then type bcc32 hello.cpp
after it compiles you test it py typing Hello.exe,
you should get the "This is my first c++ program" as an output.
It worked fine for me. any questions let me know.
