How would you go about parsing Markdown? [closed]
...
Flex is really only half the parser; once you have tokenized the input, you need to determine what the tokens mean. This is what a parser generator is for. There are lots of them. ("Parser combinator", "recursive-descent" and "LALR(1)" are key words to google for.)

Inline functions vs Preprocessor macros

Inline functions can be overloaded
The tokens passed to macros can be concatenated using operator ## called Token-Pasting operator .

std::string formatting like sprintf
