Please, what is the difference between this

void func(std::string *_str) {
    *_str = "hello";
}

void main() {
    std::string s;
    func(&s);
    std::cout << s << "n";
}

where I pass a pointer to the string into which I copy the data…

and that:

std::string func2() {
    return "hello2";
}

void main() {
    std::string s = func2();
    std::cout << s << "n";
}

where the function returns data.

In both cases, do I end up copying the data right?
