Question

Say I want to write a function like this:

int get_some_int(string index) {
    ...perform magic...
    return result;
}

However, I also want to be able to call it like this:

int var = obj.get_some_int("blah");

However, I can’t do this as const char[4] is not const string&

I could do:

int get_some_int(char* index) {
    ...perform magic...
    return result;
}

But this spews out a lot of warnings, implying it’s not how it should be done.

What is the correct way to handle string arguments then?

No, but std::string has a non-explicit conversion constructor so a temporary std::string is created, so you’re in the clear. – http://ideone.com/xlg4k
