i have .cpp file which has hello world example in it.
i don't know how to compile it from command line
any help please
thanks.

What operating system? What compiler?

With GNU compilers on Linux or on Windows XP platforms (assuming path has been set as it would be for "normal" installations:

g++ -Wall -W -pedantic test.cpp -o test


For recent Borland compilers on various Windows, assuming path has been set correctly and configurations files created as in the startup instructions:

bcc32 test.cpp

For various Microsoft compilers, assuming path and other variables have been set (Maybe by vcvrs32.bat or some such thing):

cl test.cpp /EHsc

Other compilers: Look at the documentation from the vendor.
