I programme in c++ most of the time, c++ headers can't be auto-completed after adding c-c++-default-mode-for-headers 'c++-mode) to the c-c++ variable. Solve this by modifying funcs.el(not a fancy way, but solve problem anyway):

      (setq-local company-c-headers-path-system (append '("/usr/include/c++/5/" "/usr/include" "/usr/local/include") dirs))
