[Dev-C++] How would you write a method returning a string ?

[Hiroyuki Y. <yam...@gm...>]

Hi,

I'm wondering how you would write a method returning a string.

In C, we usually return char * which malloced in the function or
returning char * which is static in the function.
(We should free the char * in the first case.)

In C++,
we have std::string, so i'm not sure what to do with it to return string.

What I'm trying to do as following.

1. use char * as a return value just like C
2. use std::string as a return value (copying the string object)
3. use std::string reference as one of the arguments (return value is
bool or something.)
4. use std::string reference as a return value

There should be more ways, but I'm not familier with those (teach me
those please)
and I don't know what's the best.
I'm going to use method 2 because
it's simple and copying string object is not a much cost I think.
(It's said that string object is 7 times as big as the pointer
size(4bytes) at the biggest in Effective STL)

Please let me know how you would write to return string.


Thanks,
