As a Linux (server side) developer, I don't know where and why should I use C++.
When I'm going to performance, the first and last choice is C.
When "performance" isn't the main issue, programming languages like Perl and Python would be good choices.
Almost all of open source applications I know in this area has been written in C, Perl and Python, Bash script, AWK and even PHP, but no one goes to use C++.
I'm not discussing about some other areas like GUI or web application, I'm just talking about Linux and about CLI and daemons.
Is there any satisfiable reason to use C++?
