    printf only accepts c-style string, that is const char * typed strings. std::string has a method, c_str that will provide a c-style version of the string.
    Code:
    printf("Hello name\n", name.c_str());

    And what would '...' be?

    Don't mix C and C++ like that. Use cout instead of printf.
