 |
|
Is this code reliable? Basically, I want to know whether returning
copy of the temporary string object is valid or not.
#include <iostream>
std::string returnString()
{
return std::string( "TempString" ) ;
}
int main()
{
std::cout<< returnString() << std::endl;
}

Yep, that's fine.

Yes completely reliable.

It's reliable in Standard C++. I've seen Microsoft Visual C++ crash while trying
to do that. A fair (and rhetorical question) would be, "Is Visual C++ reliable?"
