Makes no difference in this context for C and Java. In C++, an 
overloaded postfix ++ for a user data structure typically has to create 
and return a temporary, so modern C++ guides often recommend getting 
into the ++i habit, and using i++ only when you really need it. But no 
recommendation to rename the language to ++C yet.
