 I ran this in an arch x86_64 terminal and got this:

 {{{
 $ /usr/bin/clang++ -pipe -Os
 -isysroot/Library/Developer/CommandLineTools/SDKs/MacOSX10.13.sdk -arch
 x86_64 temp.cpp
 temp.cpp:4:11: fatal error: 'iostream.h' file not found
 # include <iostream.h>
           ^~~~~~~~~~~~
 1 error generated.
