Re: Random questions

Could you give a specific example?

static std::istringstream&
single_num (std::istringstream& is, double& num) { //... }

This `num' argument is supposed to be returned by the function.

What do you mean by "free function"?

A function that is declared outside any C++ class/struct/enum type.

Best,
Júlio.
