Hi All. In my C++ code I'm using the libc++ library and my question is about which construct is faster: for(auto line : lines) { ... } or for(auto it = lines.begin(); it != lines.end(); it++) { … } Thanks in advance for any answer. Luca.

Hi Luca, Don't use 'auto' in LLVM code for now. We still support building via some host compilers that don't support it. -Jim On Feb 3, 2012, at 7:31 AM, Luca Ciciriello <luca_ciciriello at hotmail.com> wrote: > Hi All. > > In my C++ code I'm using the libc++ library and my question is about which construct is faster: > > for(auto line : lines) > { > ... > } > > or > > for(auto it = lines.begin(); it != lines.end...
