Converting a C-style string to a C++ std::string

Question

What is the best way to convert a C-style string to a C++ std::string? In the past I\'ve done it using stringstreams. Is there a better way?

Answer 1

C++11: Overload a string literal operator

std::string operator ""_s(const char * str, std::size_t len) {
    return std::string(str, len);
}

auto s1 = "abc\0\0def";     // C style string
auto s2 = "abc\0\0def"_s;   // C++ style std::string

C++14: Use the operator from std::string_literals namespace

using namespace std::string_literals;

auto s3 = "abc\0\0def"s;    // is a std::string
