I'll second cling, when having to teach C/C++ to beginner programmers I usually start them out with cling to familiarize them with C statements/expression/printing before delving into functions. (When teaching I view high token count for hello world as a pitfall, starting with a REPL I can dive directly into computation before they start getting stuck on syntax)
