Then write your code in notepad and save it with the .cpp extension.
For example let's say you have your file saved in
c:\test\file.cpp
Then go to command prompt and do one of these ways:

HARD WAY:
type
g++ c:\test\file.cpp -o c:\test\file.exe

THE EASY WAY:
First navigate to the file path using the CD comnand:
cd c:\test

REMEMBER do not put the extension .cpp in the file's name in this method.
