Initialization: const type x((function(A)) ? B : C);

[Charlie Zender]

Hi,

I want to initialize a const with the result of a function and an
if test. Is this legal?

main(){
const std::string nvr_USER((std::getenv("USER")) ? std::getenv("USER") :
"");
}

Thanks,
Charlie

Yes. Your const is not going to be compile-time const, that's all.

main(){

int main(){

const std::string nvr_USER((std::getenv("USER")) ? std::getenv("USER") :
"");
