best way to return an std::string that local to a function

Question

In C++ what is the best way to return a function local std::string variable from the function?

std::string MyFunc()
{
    std::string mystring(\"test\");
    ret         


        

Answer 1

Well, ret will have a value of mystring after MyFunc(). In case of returning the result by value a temporary object is constructed by copying the local one.
