Since I can't return a local variable, what's the best way to return a string from a C or C++ function?

As a follow-up to [this question][1]: From what I've seen, this should work as expected: void greet(){ char c[] = "Hello"; greetWith(c); return; } but this will cause undefined behavior: char *greet(){ char c[] = "Hello"; return c; } If I'm right, what's the best way to fix the second greet function? In an embedded environment? On a desktop? [1]: https://stackoverflow.com/questions/423128/is-this-dynamic-memory-allocation
"I can make a sailboat, a pteradactyl, ..." :-o Sorry, I had an Airplane! moment when I read the question.
