How do you use Clang from the command line to compile a C++ program?

Both

clang helloworld.cpp -o helloworld

and

clang++ helloworld.cpp -o helloworld

produce errors and fail to compile. I use clang everyday as my standard C compiler but this is the first time I am experimenting with it for C++.

This was tested and will be used on both a Linux system and Mac OsX (from the command line). I have perused the man pages (and Google) but no answer jumped out at me.

For example on the Mac (Clang/LLVM installed from the apple devloper website):

$> clang helloworld.cpp -o helloworld.cpp 
clang: warning: not using the clang compiler for C++ inputs

clang: error: assembler command failed with exit code 1 (use -v to see invocation)
Retested with clang++ again on the Mac:

$> clang++ helloworld.cpp -o helloworld 
zsh: command not found: clang++
$> clang++ --help
zsh: command not found: clang++
