C++ equivalent of StringBuffer/StringBuilder?

Question

Is there a C++ Standard Template Library class that provides efficient string concatenation functionality, similar to C#\'s StringBuilder or Java\'s StringBuffer?

Answer 1

You can use .append() for simply concatenating strings.

std::string s = "string1";
s.append("string2");

I think you might even be able to do:

std::string s = "string1";
s += "string2";

As for the formatting operations of C#'s StringBuilder, I believe snprintf (or sprintf if you want to risk writing buggy code ;-) ) into a character array and convert back to a string is about the only option.
