how to construct a unique pointer that points to a certain string

Question

Given a string s e.g. auto s = std::string("hello"), how would you write code to make a unique pointer that points to a created copy of this string (not necessarily s) - I've tried many variations of auto ptr = std::make_unique<std::string>(s) but nothings seems to be working.

Answer 1

This works just fine for me:

    std::string s = "ABCDE";
    auto ptr = std::make_unique<std::string>(s);
    std::cout << s << std::endl;
    std::cout << *ptr << std::endl;
    s = "UVWXYZ";
    std::cout << s << std::endl;
    std::cout << *ptr << std::endl;

gives me output:

ABCDE
ABCDE
UVWXYZ
ABCDE

is that what you're trying to accomplish?
