possible duplicate: inline functions vs preprocessor macros inline functions introduced in c++ replace c style macros (#define macroname...), still, see lots of c++ code using old c style macros rather inlined functions, inlined function inferior old c style macros? i macros inferior inlined functions. inlined functions type safe , macros not. that's big advantage of them. compiler helping make better code. with said, there few things macros can functions cannot. there not many of these things though... i believe c programmers used macros , continue habits c++.
